[mylyn-dev] Mylyn tasks build fails - Working tree is dirty.

[Robert Munteanu]

Hi,

I am trying to work on the Mylyn tasks project to help with some bugs
I'm hitting. I've cloned the repo from gerrit and imported it as Maven
projects in Eclipse.

First problem that I have is that m2e complains about unmapped executions

Plugin execution not covered by lifecycle configuration:
org.eclipse.tycho:tycho-source-plugin:1.0.0:plugin-source (execution:
attach-source, phase: process-classes)

I'm ignoring it for now, but it's still unpleasant.

Second problem and a major one is that the Maven build fails. I'm running

$ mvn clean package

and the failure is

[ERROR] Failed to execute goal
org.eclipse.tycho:tycho-packaging-plugin:1.0.0:build-qualifier
(default-build-qualifier) on project org.eclipse.mylyn.tasks.core:
Working tree is dirty.
[ERROR] git status org.eclipse.mylyn.tasks.core:

[ERROR] You are trying to use tycho-buildtimestamp-jgit on a directory

[ERROR] Either commit all changes/add files to .gitignore, or enable
fallback to default timestamp provider by configuring
[ERROR] jgit.dirtyWorkingTree=warning for tycho-packaging-plugin
[ERROR] -> [Help 1]

I've tried appending '-Djgit.dirtyWorkingTree=warning' to the command
line, but it does not help.

The changes are generated by Eclipse when importing so I'm not sure
what to do about this.

How should I solve these issues with the Mylyn Tasks setup?

Thanks,

Robert

Hi Robert,

I think those changes are happening because you are importing the projects
as Maven projects. We don't use m2e for building Mylyn. If you import them
as Eclipse plugin projects instead, reset your repository to revert the
changes made by m2e, and let Eclipse build them you shouldn't have any
problems.

Cheers,
Sam

Indeed, that works. Thanks!
