Hello,

All of a sudden we are getting these errors on Maven 2 builds on Linux slave:
FATAL: hudson.scm.SCM.getModuleRoot(Lhudson/FilePath;Lhudson/model/AbstractBuild;)Lhudson/FilePath;
java.lang.NoSuchMethodError: hudson.scm.SCM.getModuleRoot(Lhudson/FilePath;Lhudson/model/AbstractBuild;)Lhudson/FilePath;

Maybe something has been corrupted? Where should I look?
