http://www.intellij.net/tracker/idea/viewSCR?publicId=26253 I have a build.xml such as: <taskdef name="ejbdoclet" classname="xdoclet.modules.ejb.EjbDocletTask" classpathref="xdoclet.libs" /> <target name="foo"> <ejbdoclet destdir="${gen.dir}" verbose="${verbose.value}" ejbspec="2.0"> <fileset dir="${src.dir}" includes="${ejb.files}"/> <deploymentdescriptor destdir="${gen.dd.dir}/${gen.ejb.key}" mergeDir="${merge.dd.dir}/${gen.ejb.key}"/> <remoteinterface pattern="{0}${suffix.remote}"/> ge.dd.dir}/${gen.ejb.key}"/> </ejbdoclet> </target> ejbdoclet is fine (I have added all the XDoclet libs to the Ant Build properties), however, all the subtasks except fileset are red.
