Re: [tycho-user] AspectJ weaving with org.eclipse.equinox.weaving.hook a

[iulian dragos <jaguarul@xxxxxxxxx>]

I finally managed to get this working after talking to Andew Eisenberg from the AJDT project. I post his solution here for future reference (it took me several weeks and a lot of frustration). I wonder if there is somewhere a reference of all Tycho options...

          <frameworkExtensions>

            <frameworkExtension>

              <groupId>p2.osgi.bundle</groupId>

              <artifactId>org.eclipse.equinox.weaving.hook</artifactId>

              <version>1.0.0.v20100503</version>

            </frameworkExtension>

          </frameworkExtensions>

          <bundleStartLevel>

            <bundle>

              <id>org.eclipse.equinox.weaving.aspectj</id>

              <level>2</level>

              <autoStart>true</autoStart>

            </bundle>

          </bundleStartLevel>

In short, you need both the framework extension, and make sure that the aspectj plugin is started automatically (you also need to have a dependency towards it in one of your MANIFEST.MF files).

cheers,

iulian

Hi iulian,

I ended up having tycho resolve the weaving hook with p2 into the local
Maven repository to install it in a pre-integration-test step manually.
Afterwards it can be referenced like a regular maven dependency.
Only downside is, that you depend on a specific version that might
change over time.

Hi Markus,

Thank you for your message. Unfortunately, it doesn't seem to work for me. I do get the info message:

[org.eclipse.equinox.weaving.hook] info adding AspectJ hooks ...

but nothing else. In a normal run (using the Eclipse launcher), I get a lot more, along these lines:

[org.eclipse.equinox.weaving.hook] info adding AspectJ hooks ...
[org.eclipse.equinox.weaving.aspectj] info Starting AspectJ weaving service ...
