Description Vladimir Nicolici

Build Identifier: 20100917-0705

I have a JAR maven project. After I convert the project to a faceted project and add the "Utility Module" facet, the following warning is added to the Problems list:

Classpath Dependency Validator Message: Classpath entry org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER will not be exported or published. Runtime ClassNotFoundExceptions may result.  

I can use the Ctrl+1 quick fix method and exclude the classpath entry from potential export dependencies, but as soon as I run "Update project configuration" the fix is overwritten and I have to apply it again.

I use M2E 0.12.1.20110112-1712.

https://issues.sonatype.org/browse/MNGECLIPSE-855 - Unnecessary warning "MAVEN2_CLASSPATH_CONTAINER will not be exported or published" in WTP project


Reproducible: Always

Steps to Reproduce:
1. Install Eclipse Helios SR1
2. Install M2E 0.12
3. Create a new JAR maven project
4. Convert the project to a faceted project
5. Add the "Utility Module" facet.
6. Fix the problem with Ctrl+1 and selecting "Exclude".
7. Run "Update project configuration", the problem resurfaces.

How is this different from bug 318809?

Bug 318809 was reported for a Dynamic Web Project, this bug is for a Faceted Project with a "Utility Module" facet.

Furthermore, I can reproduce the bug even when WTP integration is not installed.

Do you think I should report this bug to https://issues.sonatype.org/browse/MECLIPSEWTP, as you recommend for bug 318809?

m2e does not directly integrate with wtp and we will not make any wtp-specific changes in m2e.
