maven compilation error: duplicate classes

Question

In my maven2 project I have a directory ${basedir}/autogen that contains some autogenerated source code files produced by wsdl2java.

When running mvn compile I get an compilation error, because of duplicate classes, that lives in ${basedir}/autogen. This is true. But what is the compilation phase doing in ${basedir}/autogen? I have not told maven to add this directory as a source directory. And there seems to be no way of telling maven to ignore the directory.

Answer 1

Its hard to change default maven behaviour, i think its better to go with it - you could generate those files with maven wsdl2java-maven-plugin

Answer 2

I've seen this a few times. In almost all cases, it is due to the generated classes being added to the main src tree then checked into version control.
