As of WTP 3.0, JSDT is part of the Web Tools Platform.

Contributing to JSDT

The JSDT is driven by a very small development group with limited resources. ANY serious developers or contributors will be enthusiastically welcomed. For more information on how to become a Committer, check the standard Eclipse process (see New Committer Election). For more information about contributing to JSDT in general, or for questions about its internals, contact wtp-dev.

JSDT Functional Testing

Testing Scenarios

Reporting Bugs

Report bugs through Eclipse Bugzilla under WebTools catagory, JSDT component.

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

You can receive notifications of incoming bugs by monitoring account jsdt.javascript-inbox@eclipse.org in https://bugs.eclipse.org/bugs/userprefs.cgi?tab=email

JSDT Sources

Git Repository: webtools.jsdt.git

Detailed repository contents you can find at this page: http://wiki.eclipse.org/WTP_Git_Migration_Checklist

These plug-ins have no dependencies other than the Eclipse base (nor do they depend on anything else in WTP). Using these plug-ins, a standalone JavaScript Project can be created and used:

  • bundles/org.eclipse.wst.jsdt.core
  • org.eclipse.wst.jsdt.manipulation
  • org.eclipse.wst.jsdt.ui

The Feature project for these is:

  • features/org.eclipse.wst.jsdt.feature

Building and testing JSDT locally

Simply run mvn clean verify -Pbuild-individual-bundles -DskipTests=false. 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 site/target/repository

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:

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. 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!

Architecture

HTML an JSP editors

JSDT provides JavaScript support for the WTP HTML and JSP editors in the WTP Source Editing project Git repositories. GitHub

The following plug-in projects provide JSDT integration with WTP's HTML and JSP editors:

  • webtools.sourceediting.git/bundles/org.eclipse.wst.jsdt.web.core
  • webtools.sourceediting.git/bundles/plugins/org.eclipse.wst.jsdt.web.ui
  • webtools.sourceediting.git/bundles/plugins/org.eclipse.wst.jsdt.web.support.jsp - contains JSP-specific functionality
  • webtools.sourceediting.git/bundles/plugins/org.eclipse.wst.jsdt.support.firefox - contains bindings for Mozilla FireFox, current as of FF 2.0.x (deprecated)
  • webtools.sourceediting.git/bundles/plugins/org.eclipse.wst.jsdt.support.ie - contains bindings for Microsoft Internet explorer (deprecated)

JSDT tests

The following are the JUnits test plug-ins for JSDT:

  • tests/org.eclipse.wst.jsdt.core.tests.compiler - (test suite is org.eclipse.wst.jsdt.core.tests.compiler.JSDTTestAll)
  • 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:

  • webtools.sourceediting.tests.git/tests/org.eclipse.wst.jsdt.web.core.tests - (test suite is org.eclipse.wst.jsdt.web.core.tests.translation.AllWebCoreTests)
  • webtools.sourceediting.tests.git/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:

  • webtools.jsdt.tests.git/tests/org.eclipse.wst.jsdt.ui.tests - (test suite is org.eclipse.wst.jsdt.ui.tests.JSDTUITests)

Generating the parser

Follow the instructions at http://www.eclipse.org/jdt/core/howto/generate%20parser/generateParser.html for generating the parser. The parser grammer file is located in cvs at sourceediting/plugins/org.eclipse.wst.jsdt.core/grammer/js.g
