  Can't find a DexGuard license file.
  You should place your license file dexguard-license.txt
  1) in a location defined by the Java system property 'dexguard.license',
  2) in a location defined by the OS environment variable 'DEXGUARD_LICENSE',
  3) in your home directory, 
  4) in the class path, or
  5) in the same directory as the DexGuard jar.
