Hi!
I've followed the guide at:
http://maven.apache.org/guides/plugin/guide-ant-plugin-development.html
Unfortunately this guide does not show how to get hold of the
compile-classpath defined by the maven project model.
After some surfing i stumbled upon maven-ant-tasks which is supposed to
be capable of this.
Adding this dependency ends up in:

My questions are:
1) Is maven-plugin-plugin + maven-plugin-tools-ant still the preferred
way to develop ant-based maven plugins?
2) How can I reference the compile classpath as defined by maven in my
ant-tasks?
3) If 2 is by using maven-ant-tasks - how? (As it fails as described above).
