I have a weird problem - Some class file couldn\'t be read during maven build.
A and project B.
I had the same issue (even though the project was compiling/working fine in Eclipse), it was not when using the command line build. The reason was that I wasn't using the correct folder structure for mvn: "src/main/java/com" etc. It is looking at these folders by default (I was using "/scr/main/com" etc. which caused issues).
