title: Gradle javaexec task is ignoring jvmargs
body: <p>I am trying to run my app using a Gradle javaexec task. However, jvmargs and args are not passed to the command execution. Why?</p>
  
  <pre><code>task runArgoDev(type: JavaExec) {
      main = "org.app.ArgoDevRunner"
      classpath = configurations.testRuntime
      project.ext.jvmargs = ['-Xdock:name=Argo', '-Xmx512m', '-Dfile.encoding=UTF-8', '-Dapple.awt.textantialiasing=on', '-ea']
      project.ext.args = ['-initParameter', 'implicit-scrollpane-support=true']
  </code></pre>
  
  <p>}</p>
