 I don't know if something special has been done about ccache for Jenkins 
builds, but normally ccache for each compilations remembers a hash of 
everything the compilation depends on, and verifies it before reusing a 
cached result. Compiling the clang plugin again will change the file (unless 
somebody knows how to prevent that), and so the hash will change.
