Roman Stumm created MCOMPILER-199:
-------------------------------------
Summary: Plugin 3.0 does not compile src/main/groovy if neither
src/main/java nor src/main/resources folders exist
Key: MCOMPILER-199
URL: https://jira.codehaus.org/browse/MCOMPILER-199
Project: Maven 2.x Compiler Plugin
Issue Type: Bug
Affects Versions: 3.0
Environment: mac os, jdk 1.6 and jdk 1.7, Apache Maven 3.0.3
(r1075438; 2011-02-28 18:31:09+0100)
Reporter: Roman Stumm
The previous version 2.5.1 compiled the project that only had groovy-sources,
but after switching to version 3.0, the created jar was empty and no sources
had been compiled.
project-layout
pom.xml
src
main
groovy
MyClass.groovy
After adding a dummy-file into src/main/resources, it works.
