ANT_HOME is set incorrectly or ant could not be located. Please set ANT_HOME.
Built the following apk(s):

Also i want to know is it better to bootstrap ionic projects with yeoman? i already saw couple of tutorials doing that.

based on this link, you need to the perform the following:

  1. Download and install Ant
  2. Set the ANT_HOME environment variable to the location where Ant was installed (Right Click >> Properties >> Advanced >> Environment Variables ...)
  3. Add %ANT_HOME%\bin to your PATH
  4. Open a command line and type "ant -version", and check if it is working.

It looks like you dont have apache ant installed.go to: http://ant.apache.org/ and installed apache ant then create a ANT_HOME varriable in your system varriables and add your ant location to your PATH varriable
