How can I get Eclipse to re-compile my JUnit test when I make a change to it?

I'm using Eclipse Juno on Mac 10.7.5, Java 6, Junit 4.8.1, and Maven 3.0.3. I have imported a Maven project into Eclipse but am having trouble getting JUnit test compilations to refresh. When I edit a JUnit test in the editor, save it, right click on the test and select "Run As" -> "JUnit Test," Eclipse doesn't appear to be recompiling the test, rather using the original class file in my target/test-classes directory. When I compile on the command line using "mvn clean test-compile," the updated class appears correctly in the target/test-classes directory.

So my question is, how can I get Eclipse to properly compile my test and place it in the target/test-classes directory? I have verified in my project settings that under "Source," I have myproject/src/test/java with the output folder as myproject/target/test-classes with Included (All) and excluded (None).

This is strange. JUnit tests are treated just like any other Java file and they should be recompiled on save. First, make sure that Project -> Build automatically is enabled.

If yes, then go to the file system, delete the class file for your test and then make a whitespace change to the file from inside the IDE. Is the file regenerated? My guess is that it is.

If not, then take a look at your error log and paste any relevant errors here.
