Junit 4 tests stopped working - dependency problem?

[tomasc]

I am running a JUnit 4 testrunner in Ecllipse which previously worked and the test code is unchanged. I have substituted in and out 2 tests and get the same problem.

Unfortunately I am not sure what has changed in the dependencies since it worked (which I know points to a flaw in my process, which I am just setting up).

Perhaps someone might spot something! Thanks.

I now get an error:

Well the picture tells it all, you are mixing spring versions... You have spring 1.2.8 and 2.5.6 in one project, never do that...

[tomasc]

Thanks! I was wondering why Spring 1.2.8 was in there alright. It turns out my pom included one of my own jars whose pom had this old version of spring in there which I had not spotted.
