can't find hamcrest classes when running unit tests

Hello shea,

IntelliJ IDEA does ship with a JUnit 4 JAR, and it has a quickfix to add
it as a dependency automatically if some of your JUnit tests require it.
You can try adding the JUnit jar that ships with IntelliJ IDEA (lib\junit-4.8.jar)
as a dependency instead of the one that you took from Eclipse.

Using IntelliJ 10 CE, trying to import a couple netbeans projects.
None of my JUnit4 tests would compile, so I added the junit.jar file
that ships with eclipse as a dependancy. This let me compile my
projects with test cases.  But when I try to run them, I get the
following exception:

Exception in thread "main" java.lang.NoClassDefFoundError:

Why is it looking for the hamcrest stuff? None of my unit tests
require it. I extract the junit.jar I am using and it only contains
standard unit test stuff.  See the screen shot to see what was in it.

Doesn't IntelliJ ship with any JUnit jar files? I do have the JUnit
plugin instaled and enabled?  Is there somethign more I have to do use
JUnit? Should I have even had to manually specify a junit.jar?

Thanks,
~S

Thanks!  I couldn't figure out how to get it to auto add it.  Might be becase I was creating a project from existing sources, but manually adding thejar did the trick.

I added the J-Unit lib as a global library.  But now when I generate an ant build, the ant build fails because it can't find the jUnit libs.

My master ant file contains this:

If I check the 'include idea.home' property when I generate my ant files, everything works now.  Thanks.
