Revision as of 16:22, 31 January 2007

History

After 3.3M4, Modeling builds no longer ran their JUnit tests, due to changes in the way Eclipse packages its startup jars. The fix is trivial, but requires a change to org.eclipse.test/library.xml in addition to your local releng code.

[echo] Running org.eclipse.someproject.tests.AllTests
[java] Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/core/launcher/Main

- or -

[echo] Running org.eclipse.emf.test.build.AllSuites
[java] Unable to access jarfile {dd}/2.3.0/N200701240200/testing/N200701240200/testing/target/eclipse/startup.jar

Migration Guide

These changes should apply to anyone using PDE for builds & included JUnit tests.

Filename	Explanation	Before	After
runtests	switch from startup.jar to org.eclipse.equinox.launcher_*.jar	`cp="eclipse/startup.jar"`	cp=`find eclipse/ -name "org.eclipse.equinox.launcher_*.jar" \| sort \| head -1`
runtests	switch Main classes	`org.eclipse.core.launcher.Main`	`org.eclipse.equinox.launcher.Main`

These changes may be specific to only Modeling project builds, including EMFT builds.

Filename	Explanation	Before	After
relengbuildgtk.sh	don't pass -cp into runtests script to override value set there	`runtests -os linux -ws gtk -arch x86` `-cp eclipse/startup.jar`	`runtests -os linux -ws gtk -arch x86`
runtests	remove -noupdate flag (not supported anymore)	`org.eclipse.*.launcher.Main` `-noupdate`	`org.eclipse.*.launcher.Main`

These changes apply to you if you use org.eclipse.test (eg., in your map file, or if you run org.eclipse.test/library.xml).

plugin@org.eclipse.test=v20060926,:pserver:anonymous@dev.eclipse.org:/cvsroot/eclipse,

This is fixed by moving up to the latest version of org.eclipse.test/library.xml, according to the fix posted in bug 171756. If you can't move up, there's a hack documented in that bug as well, including a fix to avoid NullPointerException at o.e.equinox.launcher.Main.takeDownSplash (Main.java:1734), using the -nosplash flag.

Running Tests

To run tests, you'll need something like this:

$JAVA_HOME/bin/java $Xflags -enableassertions -cp $cp \
  org.eclipse.equinox.launcher.Main -ws $ws -os $os -arch $arch \
  -application org.eclipse.ant.core.antRunner -data $workspaceDir \
  -file test.xml $antTestTarget \
  $Dflags -Dws=$ws -Dos=$os -Darch=$arch -D$installmode=true $J2SE15flags \
  $properties -logger org.apache.tools.ant.DefaultLogger

The variables noted in the above example can be seen in detail in the runtests shell script.
