Execute shell script in Gradle

Question

I have a gradle build setup at the beginning of which I want to execute a shellscript in a subdirectory that prepares my environment.

task build << {
         


        

Answer 1

This works for me in my Android project

preBuild.doFirst {
    println("Executing myScript")
    def proc = "mySubDir/myScript.sh".execute()
    proc.waitForProcessOutput(System.out, System.err)
}
