Answer 1

Does the created jar contain the source code ? Why should maven try to compile this ? Are you using it as a dependency ? Or are you trying to create a jar which should contain both the compiled code and the source as well ?

Answer 2

This is a normal behavior of javac that searches the whole classpath for source files to compile unless the -sourcepath option is given (and this would be the solution here).

Unfortunately, there is a Jira issue about -sourcepath not being passed to javac by the Maven Compiler Plugin (see MCOMPILER-98). But there is a workaround:

<plugin>
  <artifactId>maven-compiler-plugin</artifactId>
  <configuration>
    <compilerArguments>
      <sourcepath>${project.basedir}/src/main/java</sourcepath>
    </compilerArguments>
  </configuration>
</plugin>
