http://issues.apache.org/bugzilla/show_bug.cgi?id=29248 Ant does not automatically parallelize independent targets. Summary: Ant does not automatically parallelize independent targets. Product: Ant Version: unspecified Platform: All OS/Version: All Status: NEW Severity: Enhancement Priority: Other Component: Core tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] CC: [EMAIL PROTECTED] We have a large source code base (hundreds of components) that are assembled in 20 or so deployments (J2EE). The whole application builds in several hours on the current machine, but we just got a 4-way machine for the build (we use it to build lots of C code as well). Ant does not take advantage of the multiple CPUs like make does. I have a big ant file that looks like this: <target name="build.foo" depends="build.bar,build.baz"> <ant dir="foo" target="build"/> </target> I know ant can execute tasks in parallel, by explicitely marking sections of the script as executable in parallel. But I don't want to go and manually compute the dependencies between 200 components... every time somebody changes dependencies. Ant already computes the dependencies, and I would like it to execute multiple independent targets in parallel. I am willing to help with coding and testing, I just need to know if somebody else has attempted this, or if there is a deep problem in the code that would require significant refactoring before this is possible. Any pointers would be appreciated.
