title: running cooja in contiki with cmd "ant run"
body: <p>When I want to run "ant run" in contiki-3.9/tools/cooja, I am facing following error:</p>
  
  <blockquote>
    <p>BUILD FAILED /home/user/contiki-3.0/tools/cooja/build.xml:199: The
    following error occurred while executing this line:
    /home/user/contiki-3.0/tools/cooja/apps/mspsim/build.xml:29: -
    Could not find the MSPSim build file. Did you run "git submodule update --init"?</p>
  </blockquote>
  
  <p>but actually I ran</p>
  
  <pre><code>             git submodule init
               git submodule update
  </code></pre>
  
  <p>before using "ant run".</p>
  
  <p>Please help me on this problem, I'm new to contiki-os and should use it for my master thesis</p>
