Executing command line scripts from Groovy on Windows

Today I had the need to create a number of dependencies within my local Maven repository (I know it's a hack you Maven purists, back off). I decided that I would use Groovy to loop over the jars in the lib directory and create the a dependency for each file. Groovyists know how easy this is:

new File('.').eachFile{
//do something
}


And of course I was aware that on Windows you have to use a "cmd /c" prior to your executable. So my final was going to look like this:


new File('.').eachFile{
groupId = it.name.substring(0, it.name.size() - 4)
"cmd /c mvn install:install-file -DgroupId=blahzy.blah-DartifactId=${groupId} -Dversion=9.9.9 -Dpackaging=jar -Dfile=${it.name}".execute().text
}


Seems appropriately short and succinct for my groovy instincts to feel okay with it. Only problem is that it didn't work. When I would run it the console would freeze and I had no idea what was going on. After reading through some of the groovy documentation online I found out that if the output is too much the Windows process will just freeze. Luckily there was a documented "hack" to solve the issue. My final script:


new File('.').eachFile{
groupId = it.name.substring(0, it.name.size() - 4)
thisCommand = "cmd /c mvn install:install-file -DgroupId=blahzy.blah-DartifactId=${groupId} -Dversion=9.9.9 -Dpackaging=jar -Dfile=${it.name}"
proc = thisCommand.execute()
proc.consumeProcessOutput()
}


So I don't get any of the output but it worked so who am I to complain.
