Build Crosswalk Stuck at downloading library

I wanted to add crosswalk browser support to my existing project, so I run the following command:
ionic browser add crosswalk@14.43.343.23

But when I run ionic build android
it's stuck at this message in the cli:

Download https://download.01.org/crosswalk/releases/crosswalk/android/maven2/org /xwalk/xwalk_core_library/14.43.343.25/xwalk_core_library-14.43.343.25.aar
