Eelco Dolstra 5d6259a973 Add a setup hook that automatically sets up $CLASSPATH
All JARs in $pkg/share/java (for each $pkg in the build inputs) are
added to $CLASSPATH.  Thus, you can say

  buildInputs = [ setJavaClassPath someJavaDependency ];

and the JARs in someJavaDependency will be found automatically by
tools like javac or ant.

Note that the manual used to say that JARs should be installed in
lib/java; this is now share/java, following the Debian policy:

  http://www.debian.org/doc/packaging-manuals/java-policy/x110.html

The directory share/java makes more sense because JARs are
architecture-independent.  (Also, a quick grep shows that we were not
exactly consistent about this in Nixpkgs.)

ECJ is an incremental Java compiler. Implemented as an Eclipse
builder, it is based on technology evolved from VisualAge for Java
compiler. In particular, it allows users to run and debug code which
still contains unresolved errors.
