Compile Sources Specific to Its Subproject But Not Sources They Depend On
Hi,
I have a directory structure that looks something like
this
-Projects/
-ProjectA/
+build/
+src/
+package1
-ProjectB/
+build/
+src/
+package2
I'm using Eclipse 3.x and have set each subproject
source to be built with in each subproject build
directory i.e. classes from ProjectA/src will be
compiled into ProjectA/build and ProjectB/src will be
compiled into ProjectB/build.
Some of the sources in ProjectA/src depends on sources
in ProjectB/src and vice versa
The classes generated by Eclipse are specific to its
subproject i.e. in ProjectA/build I will only see
package1 and the classes benefit it and package2 is
NOT generated in this subproject. The same goes for
ProjectB.
Is there anyway I could do the same for Ant? This is
because Ant generates both packages in ProjectA/build
directory. Is there a 3rd party library that allows me
to do so?
I'm using Ant 1.6.5.
Thanks
/lim/

I totally agreed with you for not having circular
dependencies between projects. Sometimes, you can't
say much when you inherit codes from the contractors
which you have no control over. Unless I bite the
bullet and break all circular dependencies in the code
there is nothing much I can do. Other option is to
have Eclipse like compiler.
I am under the impression that Eclipse uses SUN
compiler because it uses the libraries i.e. tools.jar
from the JDK directory. Am I wrong?

Hmmm, I don't know of any way to have the SUN compiler generate the
classes the way you describe if you really have circular dependencies
between the 2 projects. Eclipse must be using its own compiler to do
that.
Again, assuming you really have circular dependencies, you can't
compile projectA and projectB independently without having either's
src/ dir in the sourcepath, or the compiled classes of one in the
classpath, but to have the latter you end up with a chicken-and-egg
pb, while the former implies (with SUN's compiler) that some of the
other project classes will be output in the first projects build/ dir.
I hope I am making sense to you ;-) Good luck,

RE: Compile Sources Specific to Its Subproject But Not Sources They Depend On
Posted by TH Lim <ss...@yahoo.com>.
I have individual build.xml in each sub project. The
problem is I need to add sourcepath in each build.xml
to refer to the sources in the other project. As a
result, the sources from the other sub project are
compiled into this sub project and vice versa. This is
something I don't want.
What can I say, I inherited the code :( My only
concern now is to have the codes compiled and running
ASAP. For the time being, I'm using Eclipse IDE to
compile the codes and use Ant to jar the classes in
each sub project as an individual jar file.

This does not sound right. Ant's invocation of the javac task will place
classes into the destination directory that you specify. From what your
saying here it sounds like your build file is declaring that
"ProjectA/build" is the destination directory for both projects.
Concerning the circular dependencies - you need factor out what is common
between the two projects and push this into a new separate project that is
consumed by A and B.
Cheers, Steve.
