I’m getting this warning in Eclipse:

Classpath entry org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER will not be exported or published. Runtime ClassNotFoundExceptions may result

After searching I found that I need fix export. I did it.

Eclipse Java Build Path properties

But this warning persists!
What else can be done to fix it?
Thanks.

    I had tried both of the options but only the latter is what you need:

    • Mark the associated raw classpath entry as a publish/export
      dependency
    • Exclude the associated raw classpath entry from the set of potential
      publish/export dependencies

    If you export the dependency, refreshing the project configuration via Maven -> Update Project Configuration context menu will cause the warning to return. In this case you need to edit the .classpath file by hand:

    <classpathentry kind="con" exported="true" path="org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER">
    <attributes>
        <attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>
    </attributes>
</classpathentry>

    Simply delete have the attribute exported="true" and confirm by refreshing the project configuration.
