I've tried to download the official eclipse package from eclipse's website and
unpack it in my home. It works fine. This problem happens only with the eclipse
installation from portage.

We have junit-4.4 which normally bundles the hamcrest-core classes but ours
doesn't. And the eclipse-sdk build doesn't handle indirect deps well. Also
looked at junit.jar bundled in eclipse sources and there are also no hamcrest
classes, which means they use older version (hamcrest was added only in 4.4).

So in short, it needs to handle this indirect dep. But only Elvanor can know
how :)

Someone is working on the problem? There are some tests I can do to give a
hand?

------- Comment #3 From Jean-Noël Rivasseau 2008-03-02 20:10:12 0000 ------- 
Yes, I handle this bug, and actually I will probably work on this this week

If you want to help, just create a junit4 test and attach it (as I never wrote
junit tests yet). It should save me some time

Remember to add junit4 library to the classpath with right-click on the project
-> Build Path -> Add Libraries -> JUnit4

Thank you

OK, I got to work on this today. Unfortunately I cannot reproduce, with your
test files the test works OK (note that I dont have much experience with JUnit
tests, I just right clicked on the file and chose Run as JUnit test).

This is strange because actually it should fail yes. We use the 4.4 junit
version whereas Eclipse expects 4.3, and for 4.4 we do need the hamcrest
dependency. I know how to fix this bug - only needs a test case to reproduce.
So please try to provide me with some test that actually fail right now (maybe
yours was too simplist so did not require hamcrest) and I'll fix it ASAP.

Can anyone reproduce this bug on x86?? ali_bush maybe?

------- Comment #9 From Alistair Bush 2008-03-11 09:36:27 0000 ------- 
Works for me

Steps to Reproduce

1) Ok firstly.  Had to reemerge eclipse and its dependencies as eclipse blowing
up.
2) Created project.  Added new class and new unit test.  Copied example into
each respectively.
3) Right click on test, select Run > Run Test.
4) It runs :D

I've manually added /usr/share/hamcrest-core/lib/hamcrest-core.jar to the build
path and now it works..

------- Comment #12 From Jean-Noël Rivasseau 2008-04-09 16:23:01 0000 ------- 
What do you mean, you added hamcrest-core.jar to the build path? You mean the
project build path?

That should still not be needed IMHO. So this is clearly a bug, but
unfortunately I cannot reproduce it.

Yes, I mean the project build path.

------- Comment #14 From Jean-Noël Rivasseau 2008-04-09 18:58:56 0000 ------- 
At LAST I can reproduce the bug. I had an old version of junit-4 laying around,
that actually contained the hamcrest classes embedded.

So now that I can reproduce, I can fix it :)

------- Comment #15 From Markus Kasper 2008-05-16 19:49:39 0000 ------- 
Hi,
same bug here on x86.
The bug occured on my laptop, but 2 other computers were not infected.
First I build on my laptop and another computer the junit package.
laptop -> /usr/share/junit-4/lib/junit.jar contains no hamcrest
other computer -> /usr/share/junit-4/lib/junit.jar contains hamcrest
( same junit-4 version, junit-4.4-r1 )

So, i checked, that both portage trees were up to date -> exact same ebuild for
junit.

and then, i upgraded sun-jdk of the other computer from 1.6.0.03 to 1.6.0.05
and in junit.jar the hamcrest disappears, and the bug was on this computer,
too.

So the problem is, with sun-jdk 1.6.0.03 hamcrest was integrated in junit.jar,
with sun-jdk 1.6.0.05 there was no integration of hamcrest in junit.jar.

Perhaps this can help you.

------- Comment #16 From Pun 2008-06-11 14:57:58 0000 ------- 
Same problem on x86. It started with the upgrade to sun-jdk/1.6.0.05 and can be
worked around  by manual adding /usr/share/hamcrest-core/lib/hamcrest-core.jar
to the project build path.

------- Comment #17 From Dror Levin 2008-12-07 20:24:34 0000 ------- 
Has there been any progress? It's been more than 6 months since you said you'll
fix it now that you can reproduce it, has something changed?
I'm still having this bug on eclipse 3.4.1 with junit 4.5.

I think you will find the reason for there being a lack of progress, is the
difficulty of finding the solution.

This is the Workaround that ppl can use.

**********************************************
*************WORKAROUND***********************
**********************************************

Add the jar /usr/share/hamcrest-core/lib/hamcrest-core.jar to your build
classpath for any projects using junit4 tests.

it could also be possible that you need /usr/share/hamcrest/lib/*.jar or other
jars.  In which case adding them as well will work.

------- Comment #19 From Jean-Noël Rivasseau 2008-12-10 09:38:01 0000 ------- 
Yes, people should use the workaround for now. Due to the way Gentoo currently
packages hamcrest and JUnit, this bug is very hard to fix. At first I thought
we could fix it just by manipulating OSGi manifests, but I mailed the Eclipse
people and it looks like a patch to the Eclipse code is needed - which does not
look easy to write.
