Subject RE: how to get more debug information [SEMI-SOLUTION!]
Date Wed, 16 May 2001 13:57:00 GMT
First, let me apologize for cross-posting between the user and dev
distribution lists, but I feel that this should probably move into the dev
arena.  Sorry.

I have found a solution that works for me!!!!  It actually isn't a solution
to the lack of error text, but a solution to the bigger problem: getting
javadoc to work.  It appears to be a problem with path statements, in
relation to base directories.

The following is a "cvs diff -u Javadoc.java" of my solution:

         exe.setAntRun(project);
-        exe.setWorkingDirectory(project.getBaseDir());

+        exe.setWorkingDirectory(null);
         try {
             exe.setCommandline(toExecute.getCommandline());
             int ret = exe.execute();
-----8<-------------------------------------------------

Basically, all I did was force the external executer to use the current
working directory, as opposed to the project's base directory.


I am afraid to submit this as a patch to the current load.  The reason why
is I haven't been able to do enough testing.  I have performed tests on both
SunOS 5.6 and WinNT 4.0 platforms, using package names (as opposed to file
names).  Everything works 100% as expected for the stated scenarios.

One of the reasons why I feel that this patch won't break anyone else, is
because the <javadoc> task resolves all the filenames and paths into
absolute paths, but the task executer doesn't try to get the absolute path
for the javadoc executable itself.

Can anyone think of how this patch might break current accepted usage?  Can
anyone help me with the testing (by making this small change and testing in
your environment)?  If so, I'd greatly appreciate the peace of mind before
submitting this patch.

PS: Thanks to all the responses to my previous posts. They helped point me
in the "right" direction.
