isn;t this just zipFile.getName()?

what if you are writing a zip file in /foo/bar/wibble/zip.zip and you are archiving /bob/jane/freddy which contains a file called zip.zip - but not the same zip.zip as you are writing to?

zipFile.getName() wouldn't return the correct value. If you zip to test/archive.zip, then zipFile.getName() is archive and is not excluded correctly from the FileSet.

Hence I think we need to find a way to exclude a specific absolute path, so that it can work in all occations.

I'm trying to make a unit test with @jtnord scenario, but either my changeset doesn't introduce this regression, or I didn't reproduce the scenario correctly.

not needed use zipFile.getRemote()

I think that if you add the full path to the exclude list you should be safe.

for the same reason I've told to @jtnord, the FileSet contains relative paths to file which should be added to the zip. Using zipFile.getName() or zipFile.getRemote() wouldn't return a value which would properly exclude the file from itself

you can try to change this.zipFileName = zipFileName by this.zipFileName = zipFile.getRemote() or zipFile.getName() and you can see that it is not excluded correctly.

Archiver archiver = ArchiverFactory.ZIP.create(zipFile.write());
FileSet fs = Util.createFileSet(dir, glob);
fs.setExcludes(zipFileName);

at this point you must know where the zipFile is so must know its full canonical location and hence its absolute path.
on line 128 you know (or can obtain) the absolute path to the file you are about to add.

You just need to check that the canonical files location are not the same before calling archiver.visit.

DirectoryScanner scanner = fs.getDirectoryScanner(new org.apache.tools.ant.Project());
try {
for (String path : scanner.getIncludedFiles()) {
