Re: [tycho-user] Default Target Platform is empty while launching Eclips

[Mickael Istria <mickael.istria@xxxxxxxxxxxxxx>]

I can understand your confusion,

The issue occurs when maven-osgi-test-plugin runs tests that create plugin projects in the workspace. These plugin projects are built using the PDE target Platform as defined in Windows>Preferences>PDE>Target Platform, which is set to an empty ${eclipse_home} in the test instance. Hence plugins generated by tests in the workspace cannot compile, causing tests to fail.

In order to understand this issue, I went into the target/work folder of an eclipse-test-plugin and run the following command-line, which is almost the same as the one started by maven-osgi-test-plugin:
/usr/lib/jvm/java-1.5.0-sun-1.5.0.19/jre/bin/java -Dosgi.noShutdown=false -Dosgi.os=linux -Dosgi.ws=gtk -Dosgi.arch=x86 -Xmx512m -XX:MaxPermSize=128m -jar /home/mistria/.m2/repository/p2/osgi/bundle/org.eclipse.equinox.launcher/1.1.1.R36x_v20101122_1400/org.eclipse.equinox.launcher-1.1.1.R36x_v20101122_1400.jar -data /home/mistria/workspaceGMF/org.eclipse.gmf.tooling-root/tests/org.eclipse.gmf.tests/target/work/data -dev file:/home/mistria/workspaceGMF/org.eclipse.gmf.tooling-root/tests/org.eclipse.gmf.tests/target/dev.properties -configuration /home/mistria/workspaceGMF/org.eclipse.gmf.tooling-root/tests/org.eclipse.gmf.tests/target/work/configuration -application org.eclipse.ui.ide.workbench

Then I could manipulate the test instance, and discover that my bundles created during tests could not be built because the target platform does not contain any bundle.

I'll try to create a sample test project today in order to show you concretely the issue.

Now I am confused. Do you have problems running your tests from your IDE or from command line?

All tycho bug reports and enhancement requests should go to Eclipse
bugzilla [1].

Ok, done@ http://bugs.eclipse.org/343152

As I explained in the other thread, I think it does make sense to

make

layout of test eclipse installation configurable via
maven-osgi-test-plugin parameter.

I don't think having it configurable could help. Instead, Tycho should
create a target platform (in the same meaning as target platform in
Windows>Preferences>PDE>Target Platform) that is made of all the
bundles of the running test instance, instead of the empty
${eclipse_home} folder with using maven-osgi-test-plugin.

There are no immediate plans to work
on this feature, but patches are welcome.

This is a blocking point for moving GMF and Bonita Studio and a lot of
other projects to Tycho.

If you decide to work on a patch, you may want to way few more days
until we finish "massaging" the code for initial contribution to

eclipse

and release org.eclipse.tycho 0.12.0.

Thanks for the note. Then I'll wait for the announce telling the code
is moved to Eclipse.org. I'll first try to write a test-case.
