[ERROR] ERROR:The type Superman is already defined in Super.hero

[anatoly-spb]

I observe the same problem like the following
#12 with the master of maven-xtext-example project.

When I compile (mvn install) this example project I got:

[ERROR] ERROR:The type Superman is already defined in Super.hero. (file:/F:/javaee/eclipse_mars_workspace/maven-xtext-example/example-project/src/main/java/Super.model line : 1)

The workaround is mvn clean install, but when we have deals with big projects, this is not suitable workaround.

Use:

mvn clean install

Dont know why the sources are in the project, but when that problem ocurs to me, i cleaned with maven and re-install
