| Re: [tycho-user] How do I import a bundle-packaged project into Eclipse for debug? |
Please provide complete standalone example and exact steps to reproduce
the problem and I'll have a look.

<projectxmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0I 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.)
Here's the pom.xml for BundleGuava:

Have a look at tycho wiki [1], pomfirst-thirdparty is an example of what
I called "wrapper" bundle. In your case, you have bundle that "wraps"
guava. You just import such projects as existing Maven Projects in
eclipse, and everything should just work.

Igor -
How do I create the "wrapper" bundle? Just including the
dependency on
the BundleGuava "bundling" project does not get the Eclipse
workspace right.
Do I need to create a separate Eclipse project? Exactly how
should it
be set up? Is there an example in the m2e code base?
Thanks

Sadly, PDE does not provide API to implement this, but
there are two
workarounds
* If you have m2e/tycho integration installed, you can
import your
"wrapper" bundles in Eclipse workspace and these bundle
projects should
become available for other projects. This is what I usually do.
* Alternatively, you can copy these wrapper bundle to
<eclipse-install>/dropins folder. They should become
available for other
workspace projects after eclipse restart.

I'm trying to use Maven and m2e to develop an RCP
client that
includes
several third-partly libraries. In the past, I've been
able to
use the
custom plugin builds and a local repository of
third-party jars,
but I
was hoping to do better with Maven.
As a minimal example, I've tried to package a recent
Google Guava
release as a third-party OSGi component. I create the
component
with
"bundle" packages, and the target/../BundleGuava..jar
has all the
expected components. The rest of the details are in the
attached zip,
but the bundle instructions are:
<plugin>
<artifactId>maven-bundle-____plugin</artifactId>
<version>2.5.3</version>
<extensions>true</extensions>
<configuration>
<instructions>
<Embed-Dependency>*</Embed-____Dependency>
<Export-Package>
com.google.common.*
</Export-Package>
<_nouses>true</_nouses>
<_removeheaders>
Embed-Dependency,
Embedded-Artifacts,
Import-Package,
Private-Package
</_removeheaders>
</instructions>
</configuration>
</plugin>
However, I cannot get the client plugin, GuavaUser, to
properly
accept
the new module. I thought that the following
dependency would
make the
artifact from above available in Eclipse.
<dependencies>
<dependency>
<groupId>org.demo.bundle</____groupId>
<artifactId>BundleGuava</____artifactId>
<version>1.0.0-SNAPSHOT</____version>
</dependency>
</dependencies>
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.
