Hello Everyone,
I'm learning to use Ant 1.7.0 as part of Xcode 3.1.2 on Mac OS X 10.6.
We have a separate directory called Common/ where we keep common java
source files. These files need to get included, not all at the same time
though, when compiling our Java applications. What would be the best
way to do this?
If I add Common/ to srcdir, it compiles everything inside when I only
need a one or two. The FAQ mentions that "If you have Java source files
that aren't declared to be part of any package, you can still use the
<javac> task to compile these files correctly - just set the srcdir and
destdir attributes to the actual directory the source files live in and
the directory the class files should go into, respectively." But how to
do this exactly? Do I need two separate javac tasks like the following?
<javac srcdir="../../../Common/src" destdir="../../../Common/bin"
classpathref="lib.path" debug="on"/>
<javac srcdir="src" destdir="bin" classpathref="lib.path" debug="on"/>
that's not going to help, ant will still compile everything in common/
Two options
* <copy> only the files you need to somewhere (like build/src and
include that in the compile
* use the nested <fileset file> elements in <src> inside javac
<property name="common.dir" location="../../../Common" />
<javac destdir="${build.classes.dir}">
<src>
<fileset file="${common.dir}/Utils.java" />
<fileset file="${common.dir}/Arrays.java" />
</src>
Know that Javac will pull in extra java source files if imported, it may
compile more than you expect.
