Hi,
I'd like to use the antrun plugin to execute optional ant tasks.
Extending the example from http://maven.apache.org/guides/mini/guide-
using-ant.html , I added a dependency to ant:ant-optional:
1.5.3-1:jar, which results in an error:
An invalid artifact was detected, ArtifactID: <<< MISSING >>>.
I noticed that the used version of ant itself is 1.6.5, but I found
no matching ant-optional.jar in the repository.
Any help apreciated, see below for full details.
Thanks,
-Ralph.
