--- Comment #7 from Stefan Bodewig <bode...@apache.org> --- We have changed Ant to use a temporary directory of its own whenever it needs to create a temporary file. Likely those temporary files get removed quickly, so you never see them showing up. More details can be found here https://ant.apache.org/manual/running.html#tmpdir If you were using a single Project instance, Ant would only use a single temporary directory as it caches the name. In your case I recommend you explicitly set the property ant.tmpdir and make it point to a temporary directory under your control. This could be a Java system property or a "plain" property you set on the Project instances you create. -- You are receiving this mail because: You are the assignee for the bug.
