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


Maven Installation

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

Proxy Settings

If you need to set proxy for Maven, a snippet like this can be added to the Maven settings file:


More information on Maven settings:

Preparation Steps

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
  • modify the target platform definition used for the rest of the build

Execute the preparation step

  • Go in the <mat_src>/prepare_build/ directory
  • Execute
mvn clean install
  • This maven build is using the maven-antrun plugin to download the zip containing DTFJ. If you need to set proxy you can do it using the standard Java settings, i.e. the command line will look like this:
mvn -Dhttp.proxyHost=myProxyHost -Dhttp.proxyPort=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
  • <mat_src>/org.eclipse.mat.targetdef/ will be modified to point to this repository

Building MAT

Once the #Preparation Steps are done (normally only once) one can run the maven build for MAT.

Execute the build

  • Go to the root of the sources (there is the parent pom.xml), i.e. <mat_src>/pom.xml
  • To simply build MAT execute
mvn clean install
  • To build MAT and perform findbugs checks execut
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>/product/target/products/ - it contains all standalone RCP applications

Further Information

  • The platforms for which RCPs are built are specified in the <mat_src>/pom.xml file
  • There are two script files (build.bat and which should combine the preparation steps and the real build. However, both still need some improvements

Known Problems

Can't build RCPs for Mac

The problem is reported here: Putting a patched o.e.equinox.p2.publisher.jar under <maven_repository>/org/sonatype/tycho/tycho-p2-runtime/0.11.0/eclipse/plugins/ helps for local build.

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 Lunix or other non-Windows OS helps.

Hudson Job at Eclipse

The job at the Eclise Hudson server that performs this build is

There are still a number of TODOs:
