Updating jar fails

Hi,

I've seen this problem before on this list but no answers were given.

I'm trying to add a class file to an existing jar, but it fails silently
(does nothing whatsoever). I even try to sleep for 5 seconds so the
class file gets a newer timestamp than the jar (they end up having a
very close timestamp nonetheless).

<target name="packAWT" depends="compileAWT, init">
   <copy file="src/applet.jar" todir="dest"/>
   <sleep seconds="5"/>
   <touch file="dest/e3/e30.class"/>
   <jar destfile="dest/applet.jar"
        update="true"
	includes="dest/e3/e30.class" />
</target>

Running ant with -debug shows nothing. Ant version is 1.6.5 on Java
1.4.2_08b for Linux.

Any ideas?

Thanks,
Gad

Thanks Carol!

I've followed your advice and it works.

Now I see that the includes is relative to the basedir, so previously 
ant couldn't find the e30.class because it wasn't looking in the right 
place (although I'd expect it to complain...).

I really appreciate your help!

Cheers,
Gad

I tried it out and it worked with added basedir (removed dest from the
includes line):

<target name="packAWT" >
  <copy file="src/applet.jar" todir="dest"/>
   <sleep seconds="5"/>
   <touch file="dest/e3/e30.class"/>
  <jar destfile="dest/applet.jar" basedir="dest"
        update="true"
      includes="e3/e30.class" />
</target>

Try adding -v to your ant command to get more details about what it is doing. 

part of the verbose output I got:

packAWT:
     [copy] C:\tools\code\antstuff\updatejar\src\applet.jar omitted as
C:\tools\code\antstuff\updatejar\dest\applet.jar is up to date.
    [sleep] sleeping for 5000 milliseconds
      [jar] e3\e30.class added as e3/e30.class is outdated.
      [jar] Updating jar: C:\tools\code\antstuff\updatejar\dest\applet.jar
      [jar] adding directory META-INF/
      [jar] adding entry META-INF/MANIFEST.MF
      [jar] adding directory e3/
      [jar] adding entry e3/e30.class

I've tried both with and without a <basedir="dest">, but the results are
the same - the build succeeds, but nothing happens. I don't want to
create a new jar, just update an existing one.

I don't see a basedir attribute on the jar task, where does it point
to?
