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.
