Hi Stefan, Dominique, and all,
the classpath is fine, but it isn't set for the two target devices anyhow - so
in both rounds it is empty. The bootclasspath, however, is appended (the
first device is a MIDP/1.0 device, the second one a MIDP/2.0 one), so in the
second round I have something like this:
BootClasspath=/home/enough/workspace/enough-polish-build/import/midp1.jar:/home/enough/workspace/enough-polish-build/import/midp2.jar
whereas in the first round this is set:
BootClasspath=/home/enough/workspace/enough-polish-build/import/midp1.jar
This is not causing the current trouble (since all the "duplicate
class"-errors are in neither of both JAR files), though it will propably
become a problem later onwards.
So re-using the Javac task seems not to be possible.
So what could I do? I now would create a "wrapper"-task that accepts all
attributes as well as nested elements just like the Javac task, so that I
could instantiate a fresh Javac for each round. Apart from the necessary work
this approach means that I have to update the wrapper-task each time the
Javac task is changed. So is there a better approach? For such cases I'd love
to see a generic Task.newTaskInstance()... method ;-)
Thanks again,
Robert
