Test Jar should not include src/main/* contents

My project creates a jar and a test-jar. The first one is obviously the main program, but the second one contains test harnesses for consumption with other projects. What is annoying is how the test-jar gets all the src/main/resources contents. I don't understand (or see why or how) it should receive anything from src/main/. I actually think current behavior is incorrect; it should only get the contents from src/test/.

This is especially true since src/main/resources contains my Hibernate mappings. To prevent duplicate mappings at load time (when both jars are used), I have to exclude every resource in the test-jar.
