SpringJUnit4ClassRunner tests -- work from ant, not from IDE

Question

I have some tests that load up some Spring context files. When I run the tests from my ant target they work as expected. When I run them from IntelliJ I get a NotWritablePropertyException. I initially figured different classpaths, but the only differences are for IntelliJ's test runner.

Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'sessionAcknowledgeMode' of bean class [org.springframework.jms.listener.DefaultMessageListenerContainer]: Bean property 'sessionAcknowledgeMode' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

Answer 1

It is possible you have some classpath issues. Idea may load resource files in a different way from command line ant call.

Answer 2

The classpaths were not the same. Sorry folks.
