How to pass (cli) arguments by file in Ant

Question

Hi, I'm using Ant to build my project, generate docs and check coding strandard violations. I use some external tool through exec task. Exec prefixes the output lines with [exec]
This string messes my output up. If I specify the -e switch in the command line, it remains quiet.

Is there a way to

• specify the -e switch on every run in the build.xml file?
• or something else equivalent.

Maybe the Java System Properties will help ... see http://ant.apache.org/manual/running.html#sysprops

In particular, I think that setting the property build.compiler.emacs to true may help. Anyway, I doubt that setting (or, re-setting it via ant-extensions) it in the build file helps, as properties are designed to be immutable.
