Re: [m2e-users] example of tests for m2e plugin based on BuildContext

[Matthew Piggott <mpiggott@xxxxxxxxxxxx>]

The tests expect to be run inside an Eclipse instance.  For examples you could look at the tests in m2e source, or one of the connectors in m2e-extras ( https://github.com/sonatype/m2eclipse-extras/ ).

Thanks. I just tried using the snapshots in http://repository.sonatype.org/content/groups/sonatype-public-grid and that gets everything to compile.

But I guess it's not as easy as just copying over the m2e-connector tests, since they fail:

java.lang.IllegalStateException: Workspace is closed.
        at org.eclipse.core.resources.ResourcesPlugin.getWorkspace(ResourcesPlugin.java:367)
        at org.eclipse.m2e.tests.common.AbstractMavenProjectTestCase.setUp(AbstractMavenProjectTestCase.java:100)
        at junit.framework.TestCase.runBare(TestCase.java:132)
        at junit.framework.TestResult$1.protect(TestResult.java:110)
        at junit.framework.TestResult.runProtected(TestResult.java:128)
        at junit.framework.TestResult.run(TestResult.java:113)
        at junit.framework.TestCase.run(TestCase.java:124)
        at junit.framework.TestSuite.runTest(TestSuite.java:243)
        at junit.framework.TestSuite.run(TestSuite.java:238)

Presumably this is because AbstractMavenProjectTestCase is intended to be launched by Tycho, no by `mvn test`.

Well, I'm not married to the AbstractMavenProjectTestCase infrastructure. I just want some way to test things like:

* I modified a grammar file in Eclipse. Did the code generation run? (It should have.)
* I modified an unrelated Java file in Eclipse. Did the code generation run? (It shouldn't have.)

Any ideas of how to do this?
