BUILD FAILURE The type Superman is already

[meltzow]

Hi,

I did a clean checkout and run a maven install in parent (my.mavenized.herolanguage.releng). If I run a mvn install in example-project, I get the following error.

[INFO] Validate and generate.
[INFO] Starting validation for input: 'Super.hero'
[ERROR] ERROR:The type Superman is already defined in Super.hero. (file:/private/tmp/maven-xtext-example/example-project/src/main/java/Super.hero line : 1)

Any Ideas?

ok, looks like an "eclipse-thing". I imported the project to eclipse. If I close the projects everythings working fine, but if the projects are open, the build fails.
