SCons also makes building with Java extremely easy. Unlike the Program and Object builder methods, however, the Java builder method requires that you specify the name of a destination directory in which you want the class files placed, followed by the source directory in which the .java files live:
If the src directory contains a single hello.java file, then the output from running the scons command would look something like this (on a POSIX system):
% scons scons: Reading SConscript files ... scons: done reading SConscript files. scons: Building targets ... javac -d classes -sourcepath src src/hello.java scons: done building targets.
We'll cover Java builds in more detail, including building Java archive (.jar) and other types of file, in the chapter called Java Builds.
