I tried some systems (including importscrubber), but all required
manual intervention.
There is however one reliable solution: I do a pseudo-compile using
the KOPI compiler,
http://www.dms.at/kopi/
Calling it like this
<java classname="at.dms.kjc.Main"
fork="yes"
output="${warnings.log}"
>
<jvmarg value="-Xms256M" />
<jvmarg value="-Xmx256M" />
<arg value="--nowrite" />
<arg value="-w999" />
<arg value="@${list.of.java.files}" />
<arg value="-C${project.classpath}" />
<classpath>
<pathelement location="kjc-1.5A-bin.jar" />
</classpath>
</java>
setting the warning level to 999 and logging all output to a file. The
log contains also warnings about replacing "import blah.*;" with
imports of "blah.mayclass1, blah.myclass2,...". I found these warnings
to be reliable at all times.
However, KOPI accepts the "*" if more than 4 (or 5?) classes from the
same package get imported. But since KOPI is open source, there might
be a way to tweak the sources to remove this limit.
Best regards,
Rolf
