Re: [m2e-users] MAVEN2_CLASSPATH_CONTAINER warning in m2e 1.0.100

Thu, 25 Aug 2011 08:07:43 -0700

Is it really required? Do I have to lose all eclipse configurations for the project in order to import it?

Fabricio, before you import projects created using previous m2e versions, did you delete all eclipse related files? (.classpath, .project, .settings, etc) 


I believe it to be a required step to "upgrade" m2e version on 
existing Eclipse projects

    We started having problems deploying the app, maybe because of
    classpath issues. A college of mine created a new project, did a
    copy and paste of the contents and now things are working. It
    seems the problems is only in the import of "old" projects,
    created before m2e 1.0. As soon as I manage to create an example
    project I will file the issue in Jira.

        Does updating the maven configuration on your projects work
        after import?


        Strangely, it works only in the second time. The first time
        I run it, it shows: "Unable to update maven configuration
        for the following projects: solare-intranet" and still shows
        the error "Project configuration is not up-to-date with
        pom.xml".
        The second time, the message "Unable to update..." still
        shows, but the "Project configuration is not up-to-date..."
        is gone and the MAVEN2_CLASSPATH_CONTAINER warning appears.

        When I click to update project configuration, nothing
        appears in the console.

            I installed m2e 1.0.100 and imported an existing war
            project. I received the error: "An internal error
            occurred during: "Importing Maven projects"
            java.lang.IllegalArgumentException"

            And after I´m stuck with MECLIPSEWTP-125
            <https://issues.sonatype.org/browse/MECLIPSEWTP-125>
            but the workaround does not apply because I have an war
            project.

            Is there a fix or any other workaround?

            thanks,
