When I originally wrote the build.xml for this project my main goal was just to get it to work. This lead to a really crappy handling of preverify where you had to add the class files manually as preverify doesn’t search subdirectories for class files. So today I finally got tired of having to edit build.xml every time I added a new class, or renamed an old one. Unfortunately Google let me down except for some outdated J2ME ant extensions, but after deciphering the Ant manual I came up with this vanilla Ant code:
<!-- Find class files. -->
<fileset dir="${build}" id="tmp">
<patternset>
<include name="**/*.class">
</patternset>
</fileset>
<!-- Convert filenames to valid preverify input. -->
<!-- From: /absolute/path/to/package/SomeFile.class -->
<!-- To: package.SomeFile -->
<pathconvert pathsep=" " property="unverified" refid="tmp">
<packagemapper from="${build}/*.class" to="*">
</pathconvert>
<!-- Execute preverify on classes. -->
<exec dir="${build}" executable="${j2me.bin}/preverify">
<arg line="-classpath ${classpath.j2me}">
<arg line="-d ${preverify}">
<arg line="${unverified}">
</exec>Maybe this will save someone elses time.
