I've been looking into TUSCANY-1265 which happens on my machine but not on others machines. The symptom is that the tuscany-all... jar is empty in the binary distribution. The cause is that the shader plugin cannot copy its output (tuscany-bundle-1.0-incubating-SNAPSHOT-shaded.jar) over the to up the Bundle modules artifact (tuscany-bundle-1.0-incubating-SNAPSHOT.jar). It tries to do this by first doing a File.delete on the artifact file followed by a File.rename on the shaded file. The delete doesn't work and hence the rename fails.
I've tried repeating the shader delete/rename code in a standalone java program and it works fine so it seems to be some timing problem between Java and the filesystem or possibly to do with some garbage collection effect. I managed to get a similar effect by introducing some maven exec plugin targets. I tried to delete the artifact using maven exec and this failed as by the time the exec ran the file didn't exist. Introduce a little delay with a sleep before the exec and it does find the file. So I'll Google up any references I can find to do with Maven and timing but in the mean time does anyone have any ideas? B.t.w I'm on Windows XP SP2 with an IBM JVM. Thanks Simon
