Developer's guide to upgrading the AJDT build to a newer version of Eclipse

Steps required to change the version of Eclipse used to build and AJDT and run the tests. As an example we will consider an upgrade from Eclipse 3.3M3 to 3.3M4:

Download new Eclipse-SDK (such eclipse-SDK-3.3M4-linux-gtk.tar.gz) and also eclipse-test-framework-3.3M4.zip (listed under JUnit Plugin Tests and Automated Testing Framework)

From the CruiseControl build directory on the build machine, rename old dir "eclipse33" to "eclipse33-old-M3". Create new dir "eclipse33" and unpack new SDK into it - so that you have a path of eclipse33/eclipse/startup.jar.

Go to "test" sub-dir and rename old dir "eclipse33" to "eclipse33-old-M3". Unpack new SDK again - so that this time you have a path of eclipse33/startup.jar. Also unpack the test framework zip file at the same level. Go into eclipse33/plugins and rename org.eclipse.test_?.?.? to just "org.eclipse.test".

The script which runs the tests expects a startup.jar file in the "eclipse33" directory. Newer eclipse builds don't have this, so it needs to be copied from the plugins dir with "cp plugins/org.eclipse.equinox.launcher_.*.jar startup.jar"

That should be it, but there are often some workarounds required for specific issues. Here is the current list:

Delete test/eclipse33/plugins/org.eclipse.jdt.compiler.tool.*.jar as this new plugin requires Java 6, so will cause a warning which will result in a test failure (the tests are run under Java 5)

Edit test/eclipse33/plugins/org.eclipse.test/library.xml and add "-XX:MaxPermSize=128m" to the value of the "extraVMargs" property (see bug 130545)
