Chris,

I tried to reproduce this issue with Jenkins 1.536, Maven Integration Plugin 2.0 and Java 1.7.0_25 without success.

Can you try with these versions or give some more details like the versions you use and a project example?

I've attached to the issue the project that I use for the tests.

Regards.

Marcelo Rebasti

After installing 2.0 of the integration plugin, I'm now getting this error:

[ERROR] Failed to execute goal org.apache.openjpa:openjpa-maven-plugin:2.2.2:enhance (enhancer) on project audit-model: Execution enhancer of goal org.apache.openjpa:openjpa-maven-plugin:2.2.2:enhance failed: java.lang.ClassNotFoundException: com.gaig.annuity.entsvc.audit.model.entity.AuditActivity -> [Help 1]

I've verified this entity class exists in the proper place.

After more debugging locally, when I set the tmpClassLoader to "true" in the open-jpa-maven plugin, I get this same error locally. Is there something about the integration plugin that's enabling the temporary class loader?

Here's my jpa model pom:

Chris,

First of all, sorry by the delay in answer you.

I wasn't able to reproduce the problem inside Jenkins alone, but I was able to reproduce it by setting tmpClassLoader=true as you said, both in Jenkins as in the command line.

Jenkins don't set tmpClassLoader to any value at all.

I recommends you doing 2 tests in order to know if the problem is in your jenkins configuration or in your project:

1) Try to compile the project openjpa-project-example attached to this issue in your Jenkins. For do this, you'll need use the settings.xml that I also attached. If this build works fine, the problem is something related to your project configuration and not to any openjpa project.
2) Try to build your project in a fresh installation of Jenkins. For do this, you can download any version of Jenkins (LTS or OSS, and perhaps the same that you are using in production) and run it in your computer by executing "java -jar jenkins.war". If this build works fine, the problem have to be related to your jenkins global configuration.

If you can reproduce the problem in a fresh Jenkins installation with a simplified project, and you attach it to this issue, I'll be able to do some debug.

Regards.

Chris,

After 8 months without response I assume that the issue is resolved.

If you still have the problem, feel free to reopen the issue.
Regards.
