This page describes how Memory Analyzer can be built using Maven/Tycho. The build will
- build all bundles and features
- execute all tests
- (optional) run FindBugs static checks
- produce a p2 repository with MAT features
- produce RCPs for different platforms
- sign and upload the produced artifacts (when executed on the Eclipse Hudson server)
SVN Team Provider Installation
To import MAT sources into the IDE one can use the SVN Team Provider. Have a look at the first several steps here: MemoryAnalyzer/Contributor_Reference#Setup
The Memory Analyzer build requires a Maven 3.0.* installation. It is already present on the Hudson server at Eclipse. For local build one can download it from here.
To build the org.eclipse.mat.ui.rcp.tests project, you will need the SWTBot#Update_Sites SWTBot plugins installed. Normally, just add an update site http://download.eclipse.org/technology/swtbot/releases/latest/ and install all the plugins. See the previous link for more installation instructions.
If you need to set a proxy for Maven, a snippet like this can be added to the Maven settings file:
<proxies> <proxy> <active>true</active> <protocol>http</protocol> <port>8080</port> <host>myproxy_host</host> <nonProxyHosts>non_proxy_hosts</nonProxyHosts> </proxy> </proxies>

Checkout MAT Sources from SVN
If you want to use/edit MAT sources in the Eclipse IDE and build the same sources with Maven, then you need to take care that the directory structure is preserverd while importing the MAT projects using the SVN team provider. The following steps describe a way to do this:
- Open the 'SVN Repository Exploring' perspective
- Add the MAT Subversion repository at: https://dev.eclipse.org/svnroot/tools/org.eclipse.mat
- Select 'trunk' and open the context menu
- Select 'Find/Check Out As' from the context menu
- Select 'Find projects in the children of the selected resource'
- Select 'recursively'
- Press 'Finish'
- After some time, you'll get a window with the message: 'Following list contains projects that were automatically found on the repository. You can select project set you wish to be checked out into the workspace.'
- Keep all projects selected
- Select 'Check out as a projects into workspace'
- Select 'Respect projects hierarchy'
- Press 'Finish'
Which preparation steps are performed?
Parts of MAT depend on the IBM's DTFJ libraries, therefore one needs the libraries during the build. This preparation step will do the following:
- download DTFJ (zipped "old" update site)
- publish a p2 repository with DTFJ under <src_root>/prepare_build/target/repository
Execute the preparation step
- Go in the <mat_src>/prepare_build/ directory
mvn clean install
- This maven build is using the maven-antrun plugin to download the zip containing DTFJ. If you need to set a proxy you can do it using the standard Java settings, i.e. the command line will look like this:
mvn -DproxyHost=myProxyHost -DproxyPort=myProxyPort clean install
On the Hudson boxes at Eclipse the settings are defined as $ANT_OPTS
If the build was successful, then:
- <mat_src>/prepare_build/target/repository/ will contain the p2 repository with DTFJ
Once the #Preparation Steps are done (normally only once) one can run the maven build for MAT.
Execute the build
- Open a console and go into the <mat_src>/parent folder (there is the parent pom.xml)
- To build MAT execute
mvn clean install
- To build MAT and perform FindBugs checks execute
mvn clean install findbugs:findbugs
Where to find the results?
You can find the results of the build in the corresponding .../target/ directories for each plugin, feature, etc... Of particular interest are:
- <mat_src>/org.eclipse.mat.updatesite/target/site/ - it contains a p2 repository with MAT features
- <mat_src>/org.eclipse.mat.product/target/products/ - it contains all standalone RCP applications
- The platforms for which RCPs are built are specified in the <mat_src>/parent/pom.xml file
- There are two script files (build.bat and build.sh) which should combine the preparation steps and the real build. However, both still need some improvements
Wrong file permissions
When building MAT on a Windows box, the RCPs for any other OS will not have the proper permissions (e.g. the executables won't have the x flag). Building under Linux or other non-Windows OS helps.
Hudson Job at Eclipse
The job at the Eclise Hudson server that performs this build is https://hudson.eclipse.org/hudson/job/tycho-mat-nightly/.
The job is configured to sign the plugins and features in the update site, and to upload all artifacts to the download server. One can download such nightly/snapshot builds here: http://www.eclipse.org/mat/snapshotBuilds.php
Info: Signing is activated by the build-server profile (i.e. with parameter '-P build-server' added to the maven command)
