Hi!
We are experiencing the same problem. After adding the codehaus snapshot
repository to our Artifactory server the plexus-compiler could be
downloaded but we still get build errors.
Caused by: java.lang.NullPointerException
at
org.codehaus.plexus.compiler.javac.JavacCompiler.compile(JavacCompiler.java:120)
at
org.apache.maven.plugin.AbstractCompilerMojo.execute(AbstractCompilerMojo.java:500)
Is there any way to prevent Maven from using snapshot versions of
plugins? Just disabling the repos does not seem to suffice.
Regards,
Hendrik Busch
