Re: Multiple Java Versions

By default we use Java 1.6, but what we have done is use the "antscript" 
configuration for older projects.  The script is pretty simple and just 
wraps the default ant but explicitly sets the proper value for 
JAVA_HOME.  For example:

   #!/bin/sh
   #
   # Build with jdk 1.5 (which is not the system default)
   #

   JAVA_HOME=/path/to/jdk_1.5.0.10
   export JAVA_HOME

   ANT_CMD=${ANT_HOME}/bin/ant
   exec "$ANT_CMD" "$@"

So cruisecontrol itself uses 1.6 and any build configured with this 
script uses 1.5.

We also set the following two ant properties for javac in every project:

     <property name="ant.build.javac.source" value="1.5"/>
     <property name="ant.build.javac.target" value="1.5"/>

Hope this helps...
