@ContextConfiguration fails in Ant script when fork=false

[diehl10]

I'm using the Test Context Framework to do integration testing, along with Mockito/Powermock for mocking. I have an Ant script that runs all my tests using the junit ant task. The script works, as long as I specify fork="true" for the junit task. I can also run all of my tests directly from Eclipse.

As I keep adding integration tests, to save time when executing the tests, I want to take advantage of the context caching that the test context framework supplies, and as such, I need to remove forking. However, when I do so, I get errors for each test, complaining of FileNotFound exceptions when looking for my application context files. The error message is: java.io.FileNotFoundException: class path resource [com/docfinity/test/context/common-test-context.xml] cannot be opened because it does not exist. Again, the only change is turning fork="false".

I should note that I'm using inheritance to define multiple -context.xml files.

Here is the Ant script excerpt:

This error repeats for every test suite that I run. Why does forking the JVM cause the files to go missing from the classpath?

Trying to tackle this from another direction - is there a better way to execute all these tests than using an Ant script? Any suggestions would be helpful.
