Description

When we do clean -> compile -> compile, all Java sources are re-compiled for second compilation steps:

[framework]$ mvn clean
...
[framework]$ mvn compile
...
[INFO] --- maven-compiler-plugin:3.1:compile (precompile-sources-for-cdk) @ richfaces-framework ---
[INFO] Changes detected - recompiling the module!
[INFO] Compiling 915 source files to /mnt/workspace/workspaces/richfaces/richfaces5/framework/target/classes
...
[framework]$ mvn compile
...
