Run jar with parameters in gradle

Question

I want to run a jar file with parameters located at C:/Users/nwuser/FitNesse/fitnesse-standalone.jar in my gradle script. I know how to do it without parameters:

apply plugin: 'java'

task runJar(dependsOn:jar) << {
  javaexec { 
    main="-jar"; args "C:/Users/nwuser/FitNesse/fitnesse-standalone.jar"
  } 
}

But now I want to do something similiar like (if using the console):

java -jar fitnesse-standalone.jar -c "FrontPage?suite&format=text"

How can I apply -c "FrontPage?suite&format=text" inside my gradle script?

Kind regards !

Solution 1

args is an array, so simply supply your arguments as such:

task runJar(dependsOn:jar) << {
  javaexec { 
    main="-jar";
    args = [
            "C:/Users/nwuser/FitNesse/fitnesse-standalone.jar",
            "-c",
            "FrontPage?suite&format=text"
           ]
  } 
}

Solution 2

If you're just trying to run a FitNesse test suite with Gradle, you can add the FitNesse jar to your dependencies:

repositories {
  mavenCentral()
}

dependencies {
  compile 'org.fitnesse:fitnesse:20161106'
}

and define a JavaExec task like so:

task fitnesse(type: JavaExec) {
  classpath = sourceSets.main.runtimeClasspath

  main = 'fitnesseMain.FitNesseMain'

  args '-c', 'FrontPage?suite&format=text'
}

And then run:

$ gradle fitnesse
...
Executing command: FrontPage?suite&format=text

According to Gradle 4.3, "The Task.leftShift(Closure) method has been deprecated and is scheduled to be removed in Gradle 5.0. Please use Task.doLast(Action) instead."

In my case it failed with full package name, but it worked using just the class name: main = 'Main'
