Re: [m2e-users] Update Project resets my .classpath if local libraries are included 
What happens if you run maven->update_project twice? There is a bug or
race condition of some sort in PDE that programmatic project classpath
update unreliable, but nobody come forward to investigate and fix it yet.

I have made a sample project that illustrates the problem. You can find
it here: https://github.com/tonnymadsen/tests in m2e.tests.classpath

Just right-click the project -> Maven -> Update Project... and the
.classpath will be reduced to..nothing.

    I will see if I can re-cut down to a small example as well.

        What m2e and m2e/tycho version do you use? Are you able to

            seems to reset the .classpath of the project. Though this
            only seems to
            happen when the project includes a number of local jar files.

            My original .classpath looks as follows:

            <?xml version="1.0" encoding="UTF-8"?>
            <classpath>
            <classpathentry exported="true" kind="lib"
            path="lib/commons-lang-2.2.__jar"/>
            <classpathentry exported="true" kind="lib"
            path="lib/commons-__configuration.jar"/>
            <classpathentry kind="con"
            path="org.eclipse.jdt.__launching.JRE_CONTAINER/org.__eclipse.jdt.internal.debug.ui.__launcher.StandardVMType/__JavaSE-1.6"/>
            <classpathentry kind="con"
            path="org.eclipse.pde.core.__requiredPlugins"/>
            <classpathentry kind="src" path="src/"/>
            <classpathentry kind="output" path="target/classes"/>
            </classpath>

            And the reset version is reduced to:

            <?xml version="1.0" encoding="UTF-8"?>
            <classpath>
            <classpathentry kind="output" path="target/classes"/>
            </classpath>

            Which is a bit too limited :-) At the same time I get a
            dialog with the
            following error "lib/commons-configuration.jar [in ...] is
            not on the
            project's build path" (though I have no idea as which is the
            root cause)...

            No other project exhibit the same problem. Removing the two
            libraries,
            "solves" the problem. The MANIFEST.MF and build.properties
            files are
            both correct and not changed in the process.
