Getting Started

Similar to Mylyn/Contributor Reference this page is meant to help you contribute to the Memory Analyzer project.



Install Eclipse and configure it to develop Java 5 applications.

Setup your development environment:

  • Via the Update Manager Help -> Software Updates... install:
    • Eclipse BIRT Chart Runtime Feature
    • SVN Team Provider
    • Subversive SVN Connectors (See Subversion Team Provider Download Page for the Update Site URL)
  • Configure the Code Formatter Template:
    • Preferences -> Java -> Code Style -> Formatter -> Import... and import this template.


As the project is still in incubation, you'll find only the trunk code line. Check out the projects by saving mat.psf file locally, and then using File -> Import -> Team Project Set. Use user name "anonymous" and an empty password.

More infos: SVN_Howto, Web Access

Launch Configuration

Launch the Memory Analyzer as stand-alone RCP:

  • Create a new Eclipse Application configuration
  • Run a product: org.eclipse.mat.ui.rcp.MemoryAnalyzer
  • Launch with: plug-ins selected below only
    • Deselect org.eclipse.mat.tests
    • Deselect Target Platform and click Add Required Plug-ins
    • Select org.eclipse.pde.runtime (3.3) or org.eclipse.ui.views.log (3.4) to include the Error Log

or as feature plugged into the IDE:

  • Create a new Eclipse Application configuration
  • Run a product: org.eclipse.sdk.ide
  • Launch with: plug-ins selected below only
    • Deselect org.eclipse.mat.tests and org.eclipse.mat.ui.rcp

Export Stand-Alone RCP

To export the RCP, you need an Eclipse 3.4 IDE setup as described above.

Then open org.eclipse.mat.ui.rcp/mat.product and use the Eclipse Product Export Wizard to build the RCP.

JUnit Tests

The unit tests a placed in the org.eclipse.mat.tests project. Execute the tests by right-clicking on the project and choose Run As... -> JUnit Plug-in Test.

Build Help with DITA

  • Download DITA-OT1.4.2.1 and unzip it into C:\DITA-OT1.4.2.1
  • In plugin select DitaBuild.xml and configure the runtime configuration:
    • right click Run As > Ant Build...
    • add all the libraries from C:\DITA-OT1.4.2.1\lib into the classpath

Ideas for Contributions

This is an initial list of ideas. If you are missing a feature and have some time to contribute, please do not hesitate to contact us.

  • Application Knowledge: Name/Request Resolvers for major open source projects: Glassfish, JBoss, Jetty, Tomcat ...
  • Open Java Source file via context menu of a class
  • Check WeakHashMaps: find those where the value references the key and hence prevents garbage collection
  • Documentation and Unit Tests (pretty lame, but much appreciated!)
