Re: [tycho-user] How do I import a bundle-packaged project into Eclipse for debug? 
m2e/tycho needs Embedded-Artifacts bundle manifest header to work
properly for wrapper bundles. You should be able to enable it in
m2e-specific profile, if you don't want this header included in bundle
jars produced during command line build. But I just keep the header in
my bundles. It does not hurt anything.

Hi Igor -

Attached is a small zip file will all the parts.  There is a
bundle-parent project that provides several Maven definitions, a
BundleGuava project that should be the simple "wrapper" project, and a
BundleUser project that should be launchable as an Eclipse application.
Maven build all three (in order above), import the projects into
Eclipse, and try to launch the BundleUser project (from an Eclipse sample).

When I click on the provided action (the Eclipse icon), I get the
"java.lang.ClassNotFoundException: com.google.common.base.Joiner cannot
be found by BundleUser_1.0.0.qualifier".

This should be nearly identical to the zip file attached in the original
email.  Some small tweaks to BundleGuava project.  This was created by
cp -r of  my sample projects, deleting the .git and */target
directories, and zip -r over the remaining tree.

I'm actually working on a much larger project (DepAn), with 8+
third-party libraries (asm, guava, jogl, joda, jung, xstream, etc.).
Having a systematic scheme for creating third party libraries in Maven
versus using hacked-up custom Eclipse builds will be a boon for
generating releases.

Thanks for taking the time to look into the details.

        I must be missing something here.  My attempts to import a wrapper
        bundle still lead to a run-time ClassNotFoundException when I try to
        debug the sample application that is attached.

        I've reduced the BundleGuava project down to just a pom.xml
        file.  This
        eliminated the .project, .classpath, and META-INF/MANIFEST files
        that
        had been present in the project.  I think this packaging is
        identical to
        the packaging for the
        itp02/build01/pomfirst-__thirdparyt/pom.xml.  I do
        not have any project that resembles the
        itp02/build01/pomfirst-bundle/__pom.xml.

        When I import the BundleGuava project as an existing Maven
        project, the
        .project and .classpath files where created from scratch.  The
        Tycho and
        Eclipse compilers seem happy with this arrangement.

        However, when I try to launch the BundleUser as an Eclipse
        application,
        I get this exception:

        java.lang.__NoClassDefFoundError: com/google/common/base/Joiner
        Caused by: java.lang.__ClassNotFoundException:
        com.google.common.base.Joiner cannot be found by
        BundleUser_1.0.0.qualifier

        Although I've imported BundleGuava as an Existing Maven Project,
        the IDE
        does not seem to recognize it as a project that can be added to the
        build.  I note that is is not listed in the Debug Configuration
        page for
        Plugins.  Although I can add it a a project for the build
        dependencies,
        it does not seem to be recognized as a Workspace plugin.

        I sure I'm omitting one essential Maven attribute on some
        configuration
        page.  And I'd sure appreciate some help figuring out which
        attribute thats.

        (I'm using Guava as an example.  In my RPC application, I have a
        large
        number of more exotic libraries.  Regardless, I look forward to
        using an
        externally packaged Guava in the future.)

        bundle
                 projects should

                      * Alternatively, you can copy these wrapper bundle to

                          was hoping to do better with Maven.

                          but the bundle instructions are:

                          However, I cannot get the client plugin,

                 properly
                          accept

                          The Maven build appears to work fine, but
        Eclipse reports
                          problems.  The
                          sample call for Joiner.on(", ").join("Hello",
        "world")
                 turns into an
                          ClassNotFoundException.

                          I'd like to do most of my debugging in the
        Eclipse IDE
                          environment, but
                          that would require successful launches from
        the Eclipse
                          debugger.  What
                          is the best way to make the bundled
        third-party library
                          available to the
                          Eclipse IDE.
