```gradle
private void setJSTestDriver(Project project) {
      project.repositories {
      maven { url 'http://local:8081/artifactory/testautomation-ext-local' }
    }
    project.configurations {
      jtestdriver
    }
    project.dependencies {
      jtestdriver 'net.awired.com.googlecode.jstestdriver:jstestdriver:1.3.5'
      }
         project.tasks.add(name: "$runJSTestDriver", type: JavaExec, group: 'Sonar utils', description: 'Run JSTestDriver') {
      dependsOn project.configurations.jtestdriver
      ext.jsTestDriverResultsDir = "/jstestdriver"
      inputs.source "wwwroot"
      main = 'com.google.jstestdriver.Main'
      classpath {
        [
                project.configurations.jtestdriver,
                project.files({project.sonarutils.js.sourceDirs}),
                project.files({project.sonarutils.js.testDirs}),
                project.files("${project.getBuildDir()}" + ext.jsTestDriverResultsDir),
        ]
        args =
          [
                  "--config", "jsTestDriver.conf",
                  "--port", "9876",
                  "--browser", "${project.sonarutils.js.browserPath}",
                  "--tests","all",
                  "--testOutput", "${project.getBuildDir()}" + ext.jsTestDriverResultsDir,
                  //"--runnerMode", "DEBUG",
                  "--verbose"
          ]
      }
    }
    project.tasks.getAt(DevLanguage.JAVASCRIPT.getTaskName()).dependsOn(project.tasks.getByName(runJSTestDriver ))
  }

```

I suppose that it should download a JSTestdriver from repo when I trigger a task but something escapes me. Could you help me?

The ‘args =’ shouldn’t be inside the closure passed to ‘classpath’.

‘build.gradle’:

repositories

{ mavenCentral() }

configurations { jtestdriver }

dependencies

{ jtestdriver ‘junit:junit:4.11’ }

task runJSTestDriver( dependsOn: configurations.jtestdriver ) \<\< {

[//configurations.jtestdriver.files](https://configurations.jtestdriver.files)

}

Have to uncomment “configurations.jtestdriver.files” to make it download the dependency. Is depending on configuration really works? Javadoc mentions [“other tasks”](http://gradle.org/docs/current/javadoc/org/gradle/api/Task.html#dependencies).

You can force the resolve using something like this:

```gradle
private void setJSTestDriver(Project project) {
    project.repositories { mavenCentral() }
    project.configurations { jtestdriver }
    project.dependencies {
    jtestdriver 'junit:junit:3.8.1'
  }
    project.tasks.add(name: "runJSTestDriver", description: 'Run JSTestDriver') {
    }
    project.tasks["runJSTestDriver"].doFirst {
        project.configurations.jtestdriver.resolve()
    }
}

```

It works, but not in the way you expect it to. Depending on a ‘Buildable’ (like a ‘Configuration’) adds a task dependency on all tasks tracked by the ‘Buildable’. In your case, since the configuration only contains external dependencies, this amounts to zero tasks.

Why do you need to enforce the resolve? As soon as the configuration gets queried for its files (in one way or another), it will get resolved anyway. And if it never gets queried, why would it need to get resolved?

Thanks! I was trying to reproduce the original question scenario (if I understood it correctly) - force dependencies download when the task starts.

thank you, it was done because of hurry, I didn’t noticed a braces in incorrect place.

one more question Peter from above snippet of code how to set lazily from extensions, this below doesn’t work

```gradle
"--browser", "${project.sonarutils.js.browserPath}",

```

I figured out something like this and this works:

```gradle
"--browser", "${->project.sonarutils.js.browserPath}",

```
