How to write an ant task that removes files from a previously compiled JAR?
Let's say the files in my JAR are:
aaa/bbb/ccc/Class1 aaa/bbb/ccc/Class2 aaa/bbb/def/Class3 aaa/bbb/def/Class4 ... and I want a version of this JAR file without the aaa.bbb.def package, and I need to strip it out using ant, such that I end up with a JAR that contains:
aaa/bbb/ccc/Class1 aaa/bbb/ccc/Class2 Thanks!

Here's the process: Scan forward in the file until you find the first file you want to delete. Scan forward in the file until you find the first file you don't want to delete or you hit the central directory. Scan forward in the file until you find the first file you want to delete or you hit the central directory.
This task is used to delete a single file, directory or subdirectories. We can also delete set of files by specifying set of files. It does not remove empty directory by default, we need to use includeEmptyDirs attribute to remove that directory.
Ant tasks are the units of your Ant build script that actually execute the build operations for your project. Ant tasks are usually embedded inside Ant targets. Thus, when you tell Ant to run a specific target it runs all Ant tasks nested inside that target.
Have you tried using the zipfileset task?
<jar destfile="stripped.jar"> <zipfileset src="full.jar" excludes="files/to/exclude/**/*.file"/> </jar> For example:
<property name="library.dir" value="dist"/> <property name="library.file" value="YourJavaArchive.jar"/> <property name="library.path" value="${library.dir}/${library.file}" /> <property name="library.path.new" value="${library.dir}/new-${library.file}"/> <target name="purge-superfluous"> <echo>Removing superfluous files from Java archive.</echo> <jar destfile="${library.path.new}"> <zipfileset src="${library.path}" excludes="**/ComicSans.ttf"/> </jar> <delete file="${library.path}" /> <move file="${library.path.new}" tofile="${library.path}" /> </target> If you love us?
