grails-exec

A thin jar with no dependencies for executing Grails (with an isolated classpath) programatically (e.g from Maven or Gradle).

import grails.exec.Executor
import grails.exec.RootLoader

// Setup the classpath for Grails
def classpath = []

grailsJars.each { path ->
    classpath << new URL(path)
}

// Create a root class loader
def classloader = new RootLoader(classpath)

def executor = new GrailsExecutor(classloader, null, "/a/grails/project")
executor.execute("test-app", "integration some.package.*", "-Dsome.system.property=true")
