title: Path to repository in travis
body: <p>I am not able to locate the path to my repo (that is cloned) in travis. When I perform <code>ls</code>, there is no output. I have tried <code>ls ~/username/repo</code> and <code>ls ~/repo</code> but get <code>no such file or directory</code></p>
  
  <p>Some background: I am integrating my android app with travis-ci. I want to create a new <code>.java</code> file, before build in travis. Since this file is private and added to <code>.gitignore</code> and is on build machines only. I intend to add content to this file by using encrypted environment variable feature.</p>
  
  <p>Any custom command doesn't show the output. Not even <code>echo</code>. There is an environment variable $TRAVIS_BUILD_DIR but not sure how to use it</p>
