Question

I have a Grails project that I created using Groovy/Grails Tool Suite version 3.0.0M3 running on Windows 7 with JDK 1.7. The Grails version is 2.0.4.

There is a unit test class that was running fine until I refactored the class under test by changing method names and by adding new methods. The class under test resides in a package under src/java. The unit test class was updated to reflect the refactoring changes, but now when grails test-app is executed, the unit test reports compilation errors stating that it “cannot find symbol” All of these errors pertain to either the renamed methods or the new methods that I added. Note that the Tool Suite does not display any error markers within the project explorer pane.

I have run grails clean both from the command line and from within the Tool Suite, as well as the Tool Suite project->clean command. My BuildConfig.groovy has the correct directory set for grails.project.class.dir, and I verified that the class file within that location is being updated after a compile. Here is one of the error messages that is reported

XMLUtilTest.java:73: error: cannot find symbol

 Package pkg = u.unmarshalPackage(packageRefXml);
                ^

symbol: method unmarshalPackage(String)
location: variable u of type XMLUtil

Try the following:

1. Run refresh dependencies on your project. (Alt+G R while selecting the project) Run your tests again. Working?
2. try running test-app on the command line. Does it work?
3. You can also try right-clicking on the tests Run As -> JUnit test

My guess is that grails inside of STS is using some of the old classes. The Eclipse project will use target-eclipse/classes for its output folder, but Grails by default will use target/classes for its output folder.

I’d do a grep on the command line inside of your project for files called XMLUtil*.class and you might find where the duplicates lie.
