Subject Antwort: Re: Calling Ant using different JDKs
Date Wed, 15 Nov 2006 10:25:05 GMT
Thanks everybody for your hints!

Finally I used the good old "exec"... The project's build-file (build.xml -
doing the main job) is called by a masterbuild-file which is called by a
buildfile doing the scheduling - what needs to be build when. And this very
first call is an exec. I passed the nested env-element to it and the
problem was solved! The build result does not matter at that point in time
since the file does just the scheduling of the various project-builds.

But Prashant's idea sounds interessting to me... Thanks anyway!

Could't you try something like this :

You could define a macrodef wrapper over javac in a common-build.xml.
This can be imported by the other build files and they would use the
macrodef wrapper instead of javac directly.

Since you can control the javac version from the common-build.xml, you
can pick whatever JAVA_HOME version you want.
