| [m2e-users] Missing class when running plugin via M2E |
Hello,
I’m having a strange error log with a Maven project. Here is the error message:
Execution some-generation of goal com.mycompany.maven.plugins:some-maven-plugin:1.1.1:generate failed: A required class was missing while executing com.mycompany.maven.plugins:some-maven-plugin:1.1.1:generate: org/sonatype/aether/resolution/ArtifactResolutionException
It seems fairly straightforward, but I’m afraid it not. The build runs perfectly with the command line. It’s only when the project is analyzed by M2E that this error pops up.
The Maven plugin, which is developed in-house, has a dependency on Aether (the org.eclipse one, version 0.9.0.M3 along with the Maven runtime 3.0.3). Are these dependencies the cause of the problem? I expect the M2E dependencies and those that are needed by a Maven plugin to be independent, so using an older version of Aether in a plugin should not impact M2E, is that correct?
Thanks for your help,
Sébastien
