[tycho-user] Thirdparty POM dependencies with m2e

[Szárnyas Gábor <szarnyasg@xxxxxxxxx>]

Hello!

I'm quite new with Tycho. My goal is to use allow my Eclipse plug-ins to use third party libraries defined in a POM file. My environment is Eclipse Kepler on a Linux machine.

I started working based on this tutorial: http://wiki.eclipse.org/Tycho/How_Tos/Dependency_on_pom-first_artifacts. I understand that I need a two-phase build, first for POM-first and then manifest-first projects. Setting up the pomfirst-bundle and the tycho.demo.itp02.bundle projects was pretty straightforward and I managed to get them work.

The pomfirst-thirdparty project displayed the following error in Eclipse:

Lifecycle mapping "org.sonatype.tycho.m2e.wrapperBundle" is not available. To enable full functionality, install the lifecycle mapping and run Maven->Update Project Configuration.

However, I could not find this in the m2e Marketplace or on the web. Deleting the <plugin> element for org.eclipse.m2e:lifecycle-mapping makes the error go away and makes it possible to use Maven install on the project.

I tried to import the org.codehaus.plexus.util package from tycho.demo.itp02.bundle by adding the following lines to the bundle's manifest file:

Require-Bundle: tycho.demo.itp02.pomfirst-thirdparty;bundle-version="1.0.0"

Import-Package: org.codehaus.plexus.util;version="2.0.7"

This way, instead of using the PomFirst wrapper class, I could use the StringUtils class directly. However, I cannot import the appropriate package from the Java code ("the import ... cannot be resolved").

Can you provide me some pointers on how to do this?

Thanks,

Gabor
