Subject Re: Ant xmlproperty question,Please help me
Date Fri, 26 Mar 2010 13:09:40 GMT
Amasha,

there is
1) .classpath - an XML file
2) build.xml   - also an XML file
3) ${basedir}  - your build file's folder
4) ${ant.file}   - your build file
5) http://ant.apache.org/manual/CoreTasks/style.html - a task allowing
you to execute a XSLT stylesheet

That's pretty all you need to run a XSLT stylesheet on your Ant build
file. That stylesheet would run a XPATH query against .classpath to
extract the "excluding" entries you are looking for and insert them in
your build file where appropriate.

The only downside is, that something like

$ ant update-me-from-classpath  compile

is not working, cause Ant does not have something like "eval()".
Instead you would need to do something like

$ ant update-me-from-classpath
$ ant compile


However, I personally regard it as a bad idea to create build.xml out
of .classpath. It should be the other way round.

// Regards.
