Maven2 antrun ant jar update problem

[Walt Barrow <wa...@earthlink.net>]

Hello,

I have an ant script that I run during "install" for a project which essentially unjars the created WAR file, extracting out *.xml and *.properties files and doing a mass replacement for various tokens and then updates the WAR file with the modified files.  This ant script invokes other ant scripts, one of which is the "Tokenize.xml" script I wrote which unjars the desired files, does the token replacement, and then updates the WAR file.  When I run this script directly from the command line (i.e., ant -buildfile=...) it works every time.  When I invoke this same script from Maven2 using the AntRun plugin, it works the first time and from then on until something "magical" happens everything works except the updating of the jar file.

The Tokenize.xml file is listed below.  It simply unjars three types of files out of whatever JAR (or WAR) file it is given into a specified working directory.  Then it does token replacement on the files in that working directory.  Then it simply updates the original JAR file with any modified files.  Not very complicated.  If I run this set of scripts from Maven2, it works once, then if I rebuild immediately the jar update fails.  If I wait ten or fifteen minutes and then run again, it often will work.  I have not figured out how to turn on the verbose ant option from within AntRun, so I can't get to any meaningful diagnostic output.  I have run in the verbose mode from ant, but of course the script always works within ant!

If anyone has any ideas, I would be appreciative.

Thanks!
