Buildr exits after when Ant task completes

[Ed O'Loughlin <yu...@snkmail.com>]

Hi,

I'm using buildr to wrap the generation of a library (
http://jspeex.sourceforge.net/), which uses Ant as its own build tool. I
use

  Java.org.apache.tools.ant.Main.main(['-file', 'build.xml', 'package'])

To run the 'package' target in the Ant project. This completes but buildr
exits with a zero exit code after running this line. Nothing that follows
this in my buildfile is executed.

Any ideas?

Thanks,
Ed O'Loughlin

Looking quickly at the Ant Main source code reveals it's using
System.exit() and therefore killing the JVM upon exit.
https://github.com/apache/ant/blob/trunk/src/main/org/apache/tools/ant/Main.java

You may have to either subclass Main and override the exit() method or fork
the process to execute ant.

e.g.  java('org.apache.tools.ant.Main', '-file', 'build.xml',
'package', :classpath
=> Ant.dependencies)
