ProvisioningAction not Found [message #1706732]

I'm struggling with P2's ProvisioningActions.

I have a bundle that defines metaRequirements as given below:

metaRequirements.0.namespace=org.eclipse.equinox.p2.iu
metaRequirements.0.name=com.codetrails.events.install.rcp
metaRequirements.1.namespace=org.eclipse.equinox.p2.iu
metaRequirements.1.name=com.codetrails.events.uninstall.rcp
instructions.configure=com.codetrails.events.install.rcp.action();
instructions.unconfigure=com.codetrails.events.uninstall.rcp.action();

On install, however, I get the following error which terminates the installation process:

session context was:(profile=epp.package.standard, phase=org.eclipse.equinox.internal.p2.engine.phases.Configure, operand=null --> [R]com.codetrails.licensing.ctrlflow.starter 1.5.1.v20150829-1005-b52, action=org.eclipse.equinox.internal.p2.engine.MissingAction).

java.lang.IllegalArgumentException: No action found for: com.codetrails.events.install.rcp.action.

	at org.eclipse.equinox.p2.operations.ProvisioningJob.run(ProvisioningJob.java:177)
	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

After that error, I checked that the bundle com.codetrails.events.install.rcp is actually installed via "ss events". It is.

The bundle's plugin.xml speficies the extension:

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.4"?>
<plugin>
   <extension
         point="org.eclipse.equinox.p2.engine.actions">
      <action
            class="com.codetrails.events.install.rcp.InstallAction"
            name="action"
            touchpointType="org.eclipse.equinox.p2.osgi"
            version="1.0.0">
      </action>
   </extension>
</plugin>

Finally, when running the install process a second time, it works as expected. It looks like something goes wrong on first enabled of the install bundle.
Do you have any idea how to get more information?

I figured out that OSGI failed to resolve a package import to com.google.commons.base and thus apparently did not enable the one of the dependencies of the install bundle.

After changing the package imports to require-bundles it works as expected. However, I fear I'll run into class cast exceptions, linkage errors or even get exceptions during the installation when users install these bundles in different environments. Do you have any suggestions what might make osgi fail to resolve the com.google.common.base package ?

I'm still surprised that installing the features a second time immediately after the first attempt fails works as well.
FWIW, it seems like the uninstall/unconfigure hook does not have that problem.

Thanks for your insights,
Marcel

Hello. How did you managed to find out that OSGI failed to resolve a package import to com.google.commons.base ? I have a similar problem and I dont't know how to solve it. Thank you!
