Subject Re: javadoc task
Date Wed, 04 Jun 2008 15:49:41 GMT

Hi

I suddenly  ran into the very same error when my fileset dir attribute was
set to a root path that was just a wee bit longer than before.  As a result,
the arguments passed to the javadoc process get truncated, and the error
ensues.

I was able to work around the problem by using the usexternalfile attribute
of Ant's javadoc task, e.g.,
		<javadoc useexternalfile="true" destdir="build">
			...
			<fileset dir="${fbl.devpath}/FundServices/src">
				<include name="**/*.java" />
			</fileset>
			...
		</javadoc>
I suspect this attribute was added to precisely circumvent this problem.

Cheers
