Re: [tycho-user] tycho-demo pom first: the bundle except test bundle not started

Like I said, you need to specify both Bundle-Activator and Bundle-ActivationPolicy.

I'll need a small standalone example project to answer this question.

Igor,

Add <bundleStartlevel> to pom.xml of tycho.demo.itp02.bundle.tests as
the following solve the issue, that is, Activators are launched and the
services are registered successfully. Now the test passed.

But I wonder why I have to add them explicitly. I have other similar
projects including a test project that are all developed as Eclipse
Plugin projects, but I don't need to add <bundleStartLevel> to the test
project's pom and the test run successfully.

         <bundleStartLevel>
              <bundle>
                 <id>tycho.demo.itp02.pomfirst-thirdparty</id>
                 <level>4</level>
                 <autoStart>true</autoStart>
              </bundle>
              <bundle>
                 <id>tycho.demo.itp02.pomfirst-bundle</id>
                 <level>4</level>
                 <autoStart>true</autoStart>
              </bundle>
              <bundle>
                 <id>tycho.demo.itp02.bundle</id>
                 <level>4</level>
                 <autoStart>true</autoStart>
              </bundle>
           </bundleStartLevel>		

Thanks for your help.

Did you add Bundle-Activator and Bundle-ActivationPolicy to relevant
bundle manifests? For pom-first projects this should be done through
pom.xml configuration, check maven-bundle-plugin documentation for more
details.

If you really need to force start bundles during test execution, you
can do this with <bundleStartLevel> tycho-surefire-plugin configuration
parameter, something like

   ...
   <bundleStartLevel>
     <plugin>
       <id>...</id>
       <level>4</level>
       <autoStart>true</autoStart>
     </plugin>
   </bundleStartLevel>
   ...

Hi,

I clone the tycho demo application and tried itp02 for pom first
dependency.

The demo works well following the instruction on

http://wiki.eclipse.org/Tycho/How_Tos/Dependency_on_pom-first_artifacts.

Now I make some modification to the demo. I let PomFirst and ITP02 to

be a registered service by its Activator. The IT02Test changed as the
following:

public class ITP02Test {

      @Test

      public void basic() {

          ITP02 testee = getITP02();

          Assert.assertEquals("maven-bundle-plugin",
testee.getMessage());

      }

              private ITP02 getITP02() {

                              ServiceReference<ITP02> ref =
Activator.getContext().getServiceReference(ITP02.class ) ;

                              return
Activator.getContext().getService(ref );

              }

}

When run the test by Maven, I got the following error:

Tests in error:

    basic(tycho.demo.itp02.bundle.tests.ITP02Test): A null service
reference is not allowed.

I think this is because pomfirst-bundle and tycho.demo.itp02.bundle
are not started (not console output from their activators), so the
required services are not registered.

I cannot figure out why the two bundles are not started, by analyzing

config.ini, the two bundles are listed in osgi.bundles, but without
@4:start.

How to solve this issue?

Thanks for your help.

Guofeng
