{{JSDT}}
As of WTP 3.0, the source for JSDT is in the Web Tools Platform project (repository path /cvsroot/webtools).
+
  
WebTools source editing repositories: http://www.eclipse.org/projects/project.php?id=webtools.sourceediting
+
''JSDT'' is a subproject of ''WTP'' providing JavaScript editing features based on ''JDT''; other editors based on ''SSE''; Nodejs and JS debugging support based on ''ChromeDevTools'' and much more. Check the project pages below and see ''Developer Resources'' to get the list of Source repositories:

As Contributor, you can fix JSDT bugs and send code contributions via Gerrit:
* sourceediting/plugins/org.eclipse.wst.jsdt.web.core
+
* To start you need to sign the [https://eclipse.org/legal/CLA.php CLA] and to [setup the development environment]
* sourceediting/plugins/org.eclipse.wst.jsdt.web.ui
+
* Then pick an [https://bugs.eclipse.org/bugs/buglist.cgi?bug_status=UNCONFIRMED&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&list_id=13964165&product=JSDT open JSDT Bug], if not assigned to any team member, assign it to yourself.  
* sourceediting/plugins/org.eclipse.wst.jsdt.web.support.jsp - contains JSP-specific functionality
+
* Solve the bug and test the solution, so you can commit and push your change with Gerrit.
* sourceediting/plugins/org.eclipse.wst.jsdt.support.firefox - contains bindings for Mozilla FireFox, current as of FF 2.0.x
+
* Now wait for a committer who has to review and approve (+1) before your changes are committed.
* sourceediting/plugins/org.eclipse.wst.jsdt.support.ie - contains bindings for Microsoft Internet explorer

=== JSDT tests ===
+
== Setup the Development Environment ==
  
The following are the JUnits test plug-ins for JSDT:
+
To setup the development environment you can either use a Full Stack ''Eclipse IDE loaded with the Target Platform Plug-ins'', or use an ''Eclipse IDE'' for coding and keep a separate installation as a ''Target Platform''.  
* org.eclipse.jsdt/tests/org.eclipse.wst.jsdt.core.tests.compiler  - (test suite is org.eclipse.wst.jsdt.core.tests.compiler.JSDTTestAll)
+
* org.eclipse.jsdt/tests/org.eclipse.wst.jsdt.core.tests.model - (test suite is org.eclipse.wst.jsdt.core.tests.model.AllJavaModelTests)
+
  
These test plug-ins are new to WTP 3.1 and above:
+
Separating your development IDE from Target Platform makes your IDE lighter, more stable when adding development plug-ins and more flexible for development against different versions.
* sourceediting/tests/org.eclipse.wst.jsdt.web.core.tests  - (test suite is org.eclipse.wst.jsdt.web.core.tests.translation.AllWebCoreTests)
+
* sourceediting/tests/org.eclipse.wst.jsdt.web.ui.tests - (test suite is org.eclipse.wst.jsdt.web.ui.tests.AllWebUITests)
+
  
These test plug-ins are new to WTP 3.2 and above:
+
If you're new to this setup, watch once this video to see a full setup for JSDT development environment: https://www.youtube.com/watch?v=SFxfuudlau8 (for Mars.1).
* org.eclipse.jsdt/tests/org.eclipse.wst.jsdt.ui.tests  - (test suite is org.eclipse.wst.jsdt.ui.tests.JSDTUITests)
+
  
== JSDT packages ==
+
=== Eclipse IDE + Target Platform aside ===
  
=== JSDT Core ===
+
Download recent builds of Eclipse IDE and Target Platform from the eclipse download page: https://www.eclipse.org/downloads/
The JSDT core plugin (org.eclipse.wst.jsdt.core) provides the core JavaScript modeling.
+
  
 +
As an example, for Mars.2, you need to download:
 +
* Eclipse IDE (dev tools) : [https://www.eclipse.org/downloads/packages/eclipse-rcp-and-rap-developers/mars2 for RCP and RAP developers]
 +
* Eclipse TP (target) : [https://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/mars2 for Java EE developers]
  
{| border="1"
+
After the downloads, unzip both installations. Launch the IDE, and remember you should never launch or update the Target Platform.

=== Get the Source Code ===
 +
 
 +
''Note'': If you already have local Git repositories with JSDT projects, you can switch to Git perspective, and import them in the Git Repository View, via the "Add an existing local repository" Link. So doing, the download of projects from the project set will re-use those imported repositories, instead of doing a full download.
 +
 
 +
==== JSDT Source Repositories ====
 +
 
 +
To edit JSDT code, you will need to fetch code from four project repositories. Below you can see the Gerrit URLs.
 +
<pre>
 +
https://git.eclipse.org/r/p/jsdt/webtools.jsdt
 +
https://git.eclipse.org/r/p/sourceediting/webtools.sourceediting
 +
http://git.eclipse.org/gitroot/www.eclipse.org/webtools.git
 +
https://git.eclipse.org/r/platform/eclipse.platform.runtime
 +
</pre>
 +
 
 +
If you already provided Eclipse your [https://git.eclipse.org/r/#/settings/http-password Gerrit https password], you can clone and setup quickly by prepending your username to the URL as  <code>https://<YOUR-USERNAME>@git.eclipse.org/...</code>.
 +
 
 +
==== JSDT ProjectSet  ====
 +
 
 +
The JSDT ProjectSet defines all the project needed to develop on JSDT, along with the needed repositories.
 +
 
 +
[http://www.asegno.com/wp-content/uploads/2016/02/wst.jsdt_.allProjects_20160209.psf wst.jsdt_.allProjects_20160209.psf]
 +
 
 +
Then import all projects via:
 +
 
 +
* '''Import > Team > Team Project Set''' and choose the project set file
 +
 
 +
[[File:Import-jsdt-project-set.png|500px]]
 +
 
 +
'''Please Note''': Sometimes the ProjectSet could be not in sync with latest developments. If so, you can fix by adding missing projects, and looking in the \bundles\ folder of JSDT repositories.
 +
 
 +
==== JSDT Git Sources ====
 +
 
 +
* Git Repositories: http://git.eclipse.org/c/jsdt/webtools.jsdt.git/ webtools.jsdt.git
 +
* Developer resources https://projects.eclipse.org/projects/webtools.jsdt/developer
 +
* Detailed repository contents: http://wiki.eclipse.org/WTP_Git_Migration_Checklist

 +
== Testing ==
 +
 
 +
Here you can find information on JSDT testing by launching an inner eclipse, by building and testing locally and about functional testing scenarios.
 +
 
 +
=== Launch the Target Platform from IDE ===
 +
 
 +
Launching an inner eclipse with target platform plugins onboard, added by the plugins of which you are editing the source code:
 +
* Create a new launch configuration, based on plugins contained in the target platform
 +
* Then Run the launch configuration. You will see a new Inner Eclipse popping up.
 +
* If needed you can debug this Eclipse instance you’re going to develop against.
 +
 
 +
You can check the [https://youtu.be/SFxfuudlau8?t=9m44s video starting 9'44"] to see how to choose plug-ins and run the application.
 +
 
 +
=== Building and testing JSDT locally ===
 +
 
 +
Simply run <tt>mvn clean verify -Pbuild-individual-bundles -DskipTests=false</tt>. This command will run the Unit-tests. After the build, you can install your JSDT snapshot in an Eclipse IDE or other RCP application using the p2 repository in location <tt>site/target/repository</tt>

 +
=== JSDT Functional Testing ===
 +
[[JSDTestScenarios | Testing Scenarios ]]
 +
 
 +
== Gerrit Reviews ==
 +
 
 +
==== Pushing a new patch for review ====
 +
 
 +
You can use [[Gerrit]] (mandatory reading, important to set up hooks, SSH keys, CLA & other) to push Git commits on JSDT repositories. The repo URL for JSDT@Gerrit is <tt>ssh://user@git.eclipse.org:29418/jsdt/webtools.jsdt</tt>. Once logged into Gerrit, you can see more details about the URL at https://git.eclipse.org/r/#/admin/projects/jsdt/webtools.jsdt .
 +
 
 +
Assuming you named this repo ''gerrit'', you can push a commit to one of this repository with
 +
<source lang="bash">
 +
$ git push gerrit HEAD:refs/for/master
 +
</source>
 +
This will give you the URL of the Gerrit review where you can interact with project committers to get your commit merged.
 +
 
 +
In case you need to push another version of the patch, don't forget to copy the <tt>Change-Id</tt> from the Gerrit review if you didn't set up the git hook. Providing another version of the patch doesn't require a new commit, simply amend the one you already pushed, and push it again:
 +
<source lang="bash">
 +
$ git log -1 #Shows the commit. Message should contain Sign-Off-By and Change-Id
 +
$ git add file/to/change
 +
$ git commit --amend # add --signoff if Sign-Off-By is missing, and copy Change-Id from Gerrit review if missing
 +
$ git push gerrit HEAD:refs/for/master # will create another version of the patch, on the same review.
 +
</source>
 +
 
 +
==== Reviewing a patch ====
 +
 
 +
Incoming patch automatically triggers a build and will receive an automated vote according to whether patch breaks the build/tests or not. The CI job providing this vote is https://hudson.eclipse.org/webtools/job/jsdt-gerrit.
 +
* Anytime Hudson votes with '''<span style="color: red">-1</span>''', it generally means that something is wrong with the patch: it breaks build or make a test failing, so the patch shouldn't be merged. The build log should be inspected by submitter and reviewers to understand the cause of the bug and submit (or assist in submitting) a better patch.
 +
* Hudson voting '''<span style="color: green">+1</span>''' means that the test didn't introduce any regression visible by build or automated tests.
 +
 
 +
Anyone is free to add comments and vote on a review. Committers have the final power to decide whether or not a patch can be merged.
 +
 
 +
==== List reviews and be notified ====
 +
 
 +
You can see the list of open Gerrit reviews at https://git.eclipse.org/r/#/q/status:open+project:jsdt/webtools.jsdt,n,z .
 +
 
 +
Regular contributors and committers should really subscribe to notifications of proposed patches. You can set up notifications for proposed incoming changes at https://git.eclipse.org/r/#/settings/projects
 +
 
 +
=== Static analysis with SonarQube ===
 +
 
 +
JSDT uses SonarQube to get reports about static analysis. Those can show potential bugs, performance traps, or just bad practices. Here is the status of JSDT on these topics: https://dev.eclipse.org/sonar/dashboard/index/org.eclipse.webtools.jsdt:jsdt-parent . Any help to clean up warnings is welcome!

JSDT is a subproject of WTP providing JavaScript editing features based on JDT; other editors based on SSE; Nodejs and JS debugging support based on ChromeDevTools and much more. Check the project pages below and see Developer Resources to get the list of Source repositories:

  • JSDT: JavaScript Development Tools
  • WTP: WebTools Platform, parent project since WTP3.0
  • SSE: Structured Source Editing, for editors like XML, CSS, JSON
  • JDT: Java Development Tools, extended by the JavaScript Editor

Contributing to JSDT

The JSDT is driven by a small and dedicated development team with limited resources. ANY serious developers or contributors will be enthusiastically welcomed. For more information on how to become a Committer, read how we nominate and elect new committers according the standard Eclipse process.

To contribute to JSDT you can report bugs, resolve bugs and write documents or create media contents to spread your knowledge.

Getting in touch with the Community

For more information about contributing to JSDT or for questions about its internals you have few options:

Bugzilla for JSDT Bugs

You can Report a JSDT bug through Eclipse Bugzilla choosing WebTools category, JSDT component.

Here is a list of open JSDT bugs. We're working through them as fast as we can!

Don't forget to subscribe to Bugzilla notifications for JSDT. Here is an "how-to" reminder:

Contribute Code

As Contributor, you can fix JSDT bugs and send code contributions via Gerrit:

  • To start you need to sign the CLA and to [setup the development environment]
  • Then pick an open JSDT Bug, if not assigned to any team member, assign it to yourself.
  • Solve the bug and test the solution, so you can commit and push your change with Gerrit.
  • Now wait for a committer who has to review and approve (+1) before your changes are committed.

Below you can read how to setup the development environment, get the source code, edit the source, run the application, perform tests, and commit the changes via Gerrit.

Setup the Development Environment

To setup the development environment you can either use a Full Stack Eclipse IDE loaded with the Target Platform Plug-ins, or use an Eclipse IDE for coding and keep a separate installation as a Target Platform.

Separating your development IDE from Target Platform makes your IDE lighter, more stable when adding development plug-ins and more flexible for development against different versions.

If you're new to this setup, watch once this video to see a full setup for JSDT development environment: https://www.youtube.com/watch?v=SFxfuudlau8 (for Mars.1).

Eclipse IDE + Target Platform aside

Download recent builds of Eclipse IDE and Target Platform from the eclipse download page: https://www.eclipse.org/downloads/

As an example, for Mars.2, you need to download:

After the downloads, unzip both installations. Launch the IDE, and remember you should never launch or update the Target Platform.

Target Platform, API Baseline and Other Preferences

For the development you'll need to edit Preferences, and set the Target Platform, API Baselines and other recommended values.

Set-downloaded-instalaltion-as-target-platform.png

To set the Target Platform and the API Baseline open Windows > Preferences from menu and then select:

  • Plug-in Development > API Baseline Click "Add Baseline" and point to the Target Platform installation
  • Plug-in Development > Target Platform Click "Add.." and point to the Target Platform installation.

To set the other recommended preferences in line with the Platform_UI/How_to_Contribute guidelines open Windows > Preferences from menu and then select:

  • Preferences > General > Workspace, set text file delimiters to Unix line delimiters
  • Preferences > Java > Editor > Save Actions, enable the “Perform the selected actions ..” and set:
    • Format Source Code > Format Edited Lines: to avoid formatting the whole file, but limit the changes to edited lines.
    • Additional Actions > Remove Trailing Whitespaces: to avoid adding trailing whitespaces
  • Preferences > Java > Installed JREs add the needed JREs. Usually I add Java8, 7 and 6.

Get the Source Code

Note: If you already have local Git repositories with JSDT projects, you can switch to Git perspective, and import them in the Git Repository View, via the "Add an existing local repository" Link. So doing, the download of projects from the project set will re-use those imported repositories, instead of doing a full download.

Gerrit Reviews

Pushing a new patch for review

You can use Gerrit (mandatory reading, important to set up hooks, SSH keys, CLA & other) to push Git commits on JSDT repositories. The repo URL for JSDT@Gerrit is ssh://user@git.eclipse.org:29418/jsdt/webtools.jsdt. Once logged into Gerrit, you can see more details about the URL at https://git.eclipse.org/r/#/admin/projects/jsdt/webtools.jsdt .

Assuming you named this repo gerrit, you can push a commit to one of this repository with

$ git push gerrit HEAD:refs/for/master

This will give you the URL of the Gerrit review where you can interact with project committers to get your commit merged.

In case you need to push another version of the patch, don't forget to copy the Change-Id from the Gerrit review if you didn't set up the git hook. Providing another version of the patch doesn't require a new commit, simply amend the one you already pushed, and push it again:

$ git log -1 #Shows the commit. Message should contain Sign-Off-By and Change-Id
$ git add file/to/change
$ git commit --amend # add --signoff if Sign-Off-By is missing, and copy Change-Id from Gerrit review if missing
$ git push gerrit HEAD:refs/for/master # will create another version of the patch, on the same review.

Reviewing a patch

Incoming patch automatically triggers a build and will receive an automated vote according to whether patch breaks the build/tests or not. The CI job providing this vote is https://hudson.eclipse.org/webtools/job/jsdt-gerrit.

  • Anytime Hudson votes with -1, it generally means that something is wrong with the patch: it breaks build or make a test failing, so the patch shouldn't be merged. The build log should be inspected by submitter and reviewers to understand the cause of the bug and submit (or assist in submitting) a better patch.
  • Hudson voting +1 means that the test didn't introduce any regression visible by build or automated tests.

Anyone is free to add comments and vote on a review. Committers have the final power to decide whether or not a patch can be merged.

List reviews and be notified

You can see the list of open Gerrit reviews at https://git.eclipse.org/r/#/q/status:open+project:jsdt/webtools.jsdt,n,z .

Regular contributors and committers should really subscribe to notifications of proposed patches. You can set up notifications for proposed incoming changes at https://git.eclipse.org/r/#/settings/projects

Static analysis with SonarQube

JSDT uses SonarQube to get reports about static analysis. Those can show potential bugs, performance traps, or just bad practices.
