Subject How to Execute Groovy 2.0 Code from an Ant File that has Groovy 1.7 Classpath
Date Fri, 03 Aug 2012 17:57:44 GMT
Hi all,

My Ant script is being called with an environment including the 
classpath that includes the folder containing the groovy-all-1.7.10.jar 
file.  I want to execute Groovy 2.0 code from my Ant script.  I cannot 
change any aspect of how my Ant script is called.  I must limit my 
solution to that which I can put into my own Ant script.

My challenge is to figure a way to run groovy 2.0 code.  My attempt 
below fails to do this.  I'm hoping someone will have a solution.  
Ideally, it will NOT involve using *exec *because in the groovy code I 
will be using AntBuilder to access various tasks, macros, etc. that are 
defined back on the Ant side and I want logging information to go to the 
same logfile as well.

*Can anyone think of a way to execute some Groovy 2.0 code given that 
the classpath already includes a 1.7 Groovy jar file?*

Thanks,

Note below that the Groovy system version is 1.7.10, not 2.0.1.
