Jar Clean Up Story

I’m pretty happy with moving some common Java libraries out of the project source folders.

I have about 4 branches of the same project checked out. Each of them were about 57mb a piece. I noticed this while I was trying to sync my projects to a remote server. (I hate slow running scripts)

I managed to move the jar files out to a common folder which was about 27mb. I wrote another recursive ant clean script (which I will share below) that helped me clean up before the sync.

Moving the libraries was relatively simple with a few changes in the ant build scripts.

Anyway I managed to bring down each project to about 10mb. Here is the recursive ant clean script.



for project in $(ls $projects/);
if [ -f $projects/$project/build.xml ]; then
echo ""
echo "Cleaning $project"
cd $projects/$project
ant clean

I tried a similar script in Windows batch, didn’t work as easily. Don’t need bat files, Cygwin is better. And the same bash shell scripts on Linux most of the time with little or no modification.

For a programmer tweaking never stops. I try not to work on Sunday. But its a good day to take a step back and do backups, cleanups etc.

I knew about this jar duplication but really saw it while trying to run a backup and then looking at the projects folder with jDiskReport. Need more tools like this.
