Implicit compilation of the library classes into the test class 
directory is deplorable and should not be encourages.

Generally, library classes should be independent of any test classes and 
test class directory. As such, @build is the recommended way to build 
libraries.

That would be an anti-pattern to be discouraged. Libraries are supposed 
to be shared between tests and as such, should not be beholden to any 
individual test class directory.
