[m2e-dev] Required bundles to run m2e in a JUnit plug-in Test

[Robert Munteanu <robert.munteanu@xxxxxxxxx>]

Hi,

I am writing some tests for my plug-in and trying to enable m2e so
that I can convert the projects created in tests to m2e projects.

>From an API point of view, that was pretty easy as I used
org.eclipse.m2e.core.ui.internal.actions.EnableNatureAction . However,
when launching the test from Eclipse m2e is not properly configured
and the test fails. The first logged error is

INFO: An exception was caught and reported. Message:
java.lang.NullPointerException

    at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

I have pulled in all m2e bundles from my target platform into my test
fragment using

Require-Bundle: org.junit,
  org.eclipse.m2e.core,
  org.eclipse.m2e.launching,
  org.eclipse.m2e.jdt,
  org.eclipse.m2e.core.ui,
  org.eclipse.m2e.discovery,
  org.eclipse.m2e.editor,
  org.eclipse.m2e.editor.xml,
  org.eclipse.m2e.maven.indexer,
  org.eclipse.m2e.archetype.common,
  org.eclipse.m2e.profiles.ui,
  org.eclipse.m2e.scm,
  org.eclipse.m2e.maven.runtime,
  org.eclipse.m2e.lifecyclemapping.defaults,
  org.eclipse.m2e.model.edit,
  org.eclipse.m2e.maven.runtime.slf4j.simple,
  org.eclipse.m2e.refactoring,
  org.eclipse.m2e.profiles.core

How can I make sure m2e is properly set up in my plug-in test?

Thanks,

Robert
