Subject RE: Javac dependency checking
Date Wed, 06 Dec 2000 12:51:17 GMT
There is a bug in either the Depend source code or in my usage.  We have a
rather large project with may interdependent packages.  We consider 4 main
packages as different entities.  We need to slow down development and stop
the bleeding between these packages.  In the meantime my build.xml file
treats those packages as separate targets and I let javac deal with the
interdependencies.  But when I added the <depend> tag before the 4 <javac>
tags I am getting a problem deleting a dependent class file that has inner
classes.  The long and the short of the problem is that the Depend task
deleted a file based on one of it's inner classes, and then, later, when a
different inner class of the same outer class needs to delete the class file
I get a NPE on line 248 of Depend.  I just wrapped that if statement in a
try {} catch{NPE} because the file is already deleted.

Is that try catch really needed or am I simply using it wrong.  By the way,
my depend tag is:
    <depend srcdir="${src.dir}"
            destdir="${build.dir}"
            cache="${temp.dir}/dep.cache"
            closure="on" />

Good point.
