I seem to be unable to compile my program using the new <apt> task.
At first, I simply changed an existing javac tag to apt and tried to
compile, but received an error. I tried playing with the options,
but am still receiving similar errors. I would eventually like to
have apt locate some custom processors I've written and process
annotations, but for now I'll be happy to simply get <apt> to
duplicate <javac>.
I'm using the below code to attempt to compile my code. The below
works find if I use javac instead of apt.
<apt debug="true" destdir="${classes.dir}">
<compilerarg value="-Xlint"/>
<src>
<path refid="path.sourcepath"/>
</src>
<classpath>
<path refid="path.classpath"/>

This is the error message generated:

BUILD SUCCESSFUL (total time: 4 seconds)
This looks like a bug. Two bugs. The command line error is not being
detected as failure, and the command line is being set up wrong
1. What java version are you using?
2. Can you tease everything out into a self contained test (build
file+source files) that we could run under ant?
3. It could be the -g option. Try setting up the command by hand
without that and see if it works. Let us know the results

Hmm. Looks like it was my fault. The annotation processor I wrote was
making a call to Filer.createTextFile() with null being passed in as the
second argument (which was throwing a NullPointerException ). When I
fixed this, I was able to compile. For some reason, when I was creating
the small test case, this NullPointerException was printed out, but this
didn't happen when I was processing my large project. Does apt print a
stack trace whenever it encounters an exception?
Thanks,
Mark McKay
