It should just over-write it for you automatically...
Here is an example of what I did:
<project>
<tar destfile="DIST/ShellScripts.tar" basedir="shell"
excludes="**/cvs/**"/>
</project>
# echo "hello" > shell/foo.txt
# ant
Buildfile: build.xml
[tar] Building tar:
/home/sfloess/development/test/ant3/DIST/ShellScripts.tar
# tar tvf DIST/ShellScripts.tar
-rw-r--r-- 0/0 6 2009-10-15 13:37:50 foo.txt
# mv shell/foo.txt shell/alpha.txt
# ant
Buildfile: build.xml
[tar] Building tar:
/home/sfloess/development/test/ant3/DIST/ShellScripts.tar
BUILD SUCCESSFUL
Total time: 1 second
# tar tvf DIST/ShellScripts.tar
-rw-r--r-- 0/0 6 2009-10-15 13:37:50 alpha.txt
Note the first run the tar file had foo.txt in it...
Second run it correctly contained alpha.txt :)

Hello Everyone,
How do I get the tar task to overwrite its previously created tar file? Please
see my current target below. I don't want to delete my dist folder each time
and I don't see any options in the help section to overwrite the previous
version of ShellScripts.tar.
<target name="tar" >
<tar destfile="${dist}/ShellScripts.tar"
basedir="shell"
excludes="**/cvs/**"
/>
</target>
Thanks
Rez
