title: Zeppelin demo Java Kaa SDK from admin panel not compiling with mvn
body: <p>There are two ways in which a kaa app sdk can be downloaded from the sandbox. One from the front panel of the kaa sandbox and the second from the admin panel.</p>
  
  <p>These two java sdk downloads for zeppelin demo are very different. The first method gives lib and src directories after extraction but the 2nd gives com, org and META-INF directories. The first download compiles perfectly fine with mvn but the second does not compile at all. Why are these two downloads different?</p>
  
  <p>Also, whenever I make changes to any schema, can I download the changed sdk from the sandbox front panel or do I have to always download it from the admin panel?</p>
