title: Gradle "... occurred starting process 'command 'npm''" on Mac
body: <p>I have MacOS with IntelliJ Idea installed. I'm using Gradle (gradle-2.4) for building the project. I have NodeJS and NPM installed on the Mac and available from the shell.</p>
  
  <pre><code>MacBook:~ user$ node -v
  v4.2.2
  MacBook:~ user$ npm -v
  2.14.7
  </code></pre>
  
  <p>When running Gradle task that uses NODE/NPM, it fails with the following error (in current example it is NPM).</p>
  
  <pre><code>* What went wrong:
  Execution failed for task ':module:task'.
  &gt; A problem occurred starting process 'command 'npm''
  </code></pre>
  
  <p>The error stack trace from Gradle is the following.</p>
  
  <pre><code>Exception is:
  org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':module:task'.

  <p>So it looks like Gradle is trying to find NPM in the project absolute directory and doesn't use Mac PATH environment variable. Anyone knows how to avoid/workaround this? I cannot use absolute path for NODE/NPM as the team is shared and using different OSes (Linux, MacOS). Any ideas? :)</p>
