My idea how to fix the macro was to use the similar approach like the javadocs-packages-file downloader. This was invoked by "antcall", so if/unless properties were respected and updated. The idea I had was the same: use {{<local>}} to define property, then {{<uptodate>}} on the local property to find out if source files are newer than {{@destdir/package.html}} (this is the recommended approach to detect javadocs timestamp, see e.g. the official ANT build.xml), and finally execute the javadocs task with {{<antcall>}}, passing the {{@}}-variables as parameters to the task. The problem why this did not work is the {{<nested>}} sourcefiles property, you cannot pass xml structures as parameters to a target. I found no was around that. The second problem: You cannot get the source folder with the Java files from the macro: you only have the nested element that has the package names and directories somewhere in them. In my opinion the only was to fix this would be a separate uptodate task in common-build and all module's javadocs targets depend on that one + ifunless check. was (Author: thetaphi): Hi, status update: It is not as easy as expected.
