Running Groovy script from Gradle using GroovyShell: Exception in thread “main” java.lang.NoClassDefFoundError: org/apache/commons/cli/ParseException

Question

I want to run a groovy command-line script from my Gradle build script.

I\'m using this code in my Gradle script:

def groovyShell = new GroovyShell(         


        

Answer 1

The alternative to do this is the following:

buildScript {
  repositories { mavenCentral() }
  dependencies {
    classpath "commons-cli:commons-cli:1.2"
  }
}

def groovyShell = new GroovyShell()
....

This puts the commons-cli dependency on the classpath of the buildscript instead of on the classpath of the project to be built.
