I have 2 builds of the same project on the same Hudson/Jenkins server (they are running different build profiles). The both build when polling SCM, but I sometimes get the following error:
The plugin 'org.apache.maven.plugins:maven-checkstyle-plugin' does not exist or no valid version could be found
This only started once I added the second build, so I’m assuming there is some sort of conflict. Does anyone know what’s going on here?
thanks,
Jeff
Are your builds running at the same time, with the same Maven instance and the same local Maven repository? If so, then maybe you run into a filelock on that plugin jar. I have the same problem here, if two jobs are accessing the same Maven artifact at the same time, they fail, because Maven can’t handle that.
I solved that with two Maven instances, with a separate local repository.
It could also help, if you set the VCS polling of the second job a minute after the first job.
