Groovy script to run grails command

I wanted to create a groovy script to run grails clean, grails compile and grails run-app, However, I noticed that I cannot run any of the grails commands. In fact then I tried to run the following script on the Groovy Console:

 def envs = System.getenv().collect{"$it.key=$it.value"}
    //println envs
    println "java -version".execute(envs, new File("c:\\")).err.text
    println "grails -version".execute(envs, new File("c:\\")).text

This itself gives me the following output:

groovy> def envs = System.getenv().collect{"$it.key=$it.value"} 
groovy> //println envs 
groovy> println "java -version".execute(envs, new File("c:\\")).err.text 
groovy> println "grails -version".execute(envs, new File("c:\\")).text 


    java version "1.7.0_06"
    Java(TM) SE Runtime Environment (build 1.7.0_06-b24)
    Java HotSpot(TM) 64-Bit Server VM (build 23.2-b09, mixed mode)

    Exception thrown

    java.io.IOException: Cannot run program "grails" (in directory "c:\"): CreateProcess error=2, The system cannot find the file specified

        at ConsoleScript26.run(ConsoleScript26:4)

    Caused by: java.io.IOException: CreateProcess error=2, The system cannot find the file specified

        ... 1 more

Has anyone faced this problem before?

On Windows, the grails command is a .bat file, and you can't run .bat files directly using Runtime.exec or ProcessBuilder (which is what "...".execute ultimately delegates to).

Use cmd /c:

println ["cmd", "/c", "grails -version"].execute(envs, new File("c:\\")).text

or possibly

println ["cmd", "/c", "grails", "-version"].execute(envs, new File("c:\\")).text

I'm not sure whether the "grails -version" needs to be one argument or two (it may be that both ways work, I'm not currently in a position to test this).

If java - version runs and grails -version not, it means that you don't updated your PATH environment variable. Append the location to the bin folder to the variable.

Since Grails is just a zip, you need to do it manually.
