Ant 1.10.8 adds a convenience property to change the temporary directory. It was already possible to change it in prior versions with:
ANT_OPTS=-Djava.io.tmpdir=~/temp ant jar Now it's possible to use: ant jar -Dant.tmpdir=~/temp Or by setting the ant.tmpdir property inside the Ant build.xml file. Since it requires an action from the user and the issue is already avoidable I'm tempted to think a backport to stable isn't important. Emmanuel Bourg
