Re: [platform-releng-dev] Junit bundles problems on Gentoo Linux

Hi Jean-Noël

Please use the jdt-ui-dev list or open
a bug against JDT/UI to continue discussions on this topic.

Our plan is to support JUnit 4.4 in
Eclipse 3.4, see https://bugs.eclipse.org/bugs/show_bug.cgi?id=197170 .

Getting JUnit 4.4 support in Eclipse
3.3 with a separate hamcrest.jar is not trivial. You would have to
update our custom classpath setup code
(in org.eclipse.jdt.junit/org.eclipse.jdt.internal.junit.buildpath),
and probably also the JUnitLaunchConfigurationDelegate.
We only support the JUnit bundles that are shipped with Eclipse.

HTH,

Markus Keller,
Eclipse JDT/UI Committer

Subject	[platform-releng-dev] Junit bundles problems on Gentoo Linux

Hi, 

I am the current maintainer of Eclipse (Europa) on Gentoo Linux. I do need
to establish a working relationship with upstream, as some of the bugs
I am faced are quite complex and I feel I won't be able to solve them without
some help or documentation about Eclipse inner workings.

So I am writing to this list in the hope of establishing contact. If this
is not the appropriate place, please redirect me to the correct one. I
already posted to the linux-distro Eclipse ML but did not get much help
yet (as people there are not upstream).

Here is a copy of a post I made to the forums, but did not receive any
answer:

I am faced with a Junit bug. The Junit 4 version bundled with Eclipse is
normally 4.3, but on Gentoo we use 4.4. 4.4 has a dependency on some of
hamcrest classes.

Thus currently when trying to load a Junit 4 test on Gentoo Eclipse, a
CNF exception occurs regarding the hamcrest classes.

So I tried to fiddle with the manifest in the Junit 4 bundle to include
a dependency to our local system hamcrest jar. However so far I have not
been successful.

My questions are:

1) Am I on the right path at all? Eg, if the user adds a Junit library
via the normal Eclipse mechanism (Configure Build Path -> Add Library
-> JUnit), will the OSGi framework resolves the dependencies or not?
If the only effect of adding junit this way is to add an entry to the project
classpath, I guess not.

2) Normally the junit bundles are exploded, eg in a folder. I tried to
jar the folder, removed the Bundle-ClassPath OSGi header attribute. But
then something strange happens: everytime I load Eclipse, it creates in

/home/elvanor/.eclipse/org.eclipse.platform_3.3.0_1169174242/configuration/org.eclipse.osgi/bundles/34/1/.cp

the contents of this jar. When I add the Junit library via the mechanism
I described, it shows a junit.jar file which is not present (as I removed
it, but also removed it from the Bundle-ClassPath). Then nothing works
at all, eg I cannot even start a Junit test.

So what's happening exactly, what is Eclipse doing?

Thanks for helping,

Jean-Noel_______________________________________________
