Subversion with Groovy via AntBuilder() and svnant

This took me a while to figure out and to get it all working.

I wanted to do svn operations from as groovy script without going near the svnkit API.

The other problem was having the runtime dependencies available from wherever the script is run from.

 @GrabConfig(systemClassLoader=true)  
                     @GrabResolver(name="fid", root="http://path-to-internal-repo/nexus/content/groups/mygroup")  
                     @Grab(group='org.tmatesoft.svnkit', module='svnkit', version='1.3.5')   
                     @Grab(group='org.tigris', module='svnant', version='1.3.0')   
                     @Grab(group='org.tigris', module='svnClientAdapter', version='0.9.102')   
                     @Grab(group='org.tmatesoft.svnkit', module='svnkit-javahl', version='1.3.5')  
                def message='Commited by jenkins admin - updated parent pom to my:parent:1.23'  
                     def ant = new AntBuilder()  
 ant.svn(username:"username", password:"password",failonerror:"false") {  
                     commit(file: pomFile, message:message )  
                }  
 ant.typedef(resource: "org/tigris/subversion/svnant/svnantlib.xml")  
ant.svn(username:"user", password:"password")
{
 checkout(url: "svn://svnserver/project/trunk", destPath: "/home/user/topath")
}

Using ~/.groovy/grapeConfig.xml
