This shouldn't happen. Can you provide the exact error message, stack trace, etc.?

Here is the error message from my console:

/Users/petrovic/Projects/acme/qa/lib/atf-core/geb-browser-parent/geb-dpsbrowser/src/main/groovy/com/acme/qa/dpsbrowser/DPSBrowserImpl.groovy: 162: unable to resolve class ServiceType
@ line 162, column 73.
imit(String partnerShortName, ServiceTyp
^

I will try to reproduce in a test project. If I cannot, this is all I can offer at the moment.

Ok, I am able to reproduce this in a test project.

Here is my console output:

mb:gradle-rename-enum> rm -rf .gradle/

Here is my build script:

apply plugin: 'groovy'

repositories {
mavenCentral()
}

dependencies {
groovy group: 'org.codehaus.groovy', name: 'groovy-all', version: '2.0.5'
}

And here are the source files:

An enum that I move from src/main/groovy to src/main/java:

package somepackage;

public enum SomeEnum {
A, B
}

The client code:

package somepackage

class AScript {

def foo() {
SomeEnum someEnum = SomeEnum.A
}
}

My Gradle version:

gradle -v

------------------------------------------------------------
Gradle 1.2
------------------------------------------------------------

Gradle build time: Wednesday, September 12, 2012 10:46:02 AM UTC
Groovy: 1.8.6
Ant: Apache Ant(TM) version 1.8.4 compiled on May 22 2012
Ivy: 2.2.0
JVM: 1.6.0_37 (Apple Inc. 20.12-b01-434)
OS: Mac OS X 10.6.8 x86_64

I re-ran the scenario with Gradle 1.3. It behaves the same as 1.2.

Workaround is to run with --rerun-tasks
