When syncing Android Studio with the build.gradle, the sync fails with this exception in the generateJsonModel task.

Are you one Windows by any chance? Are you using Clang or GCC?

+chiur, this looks like the response file line ending problem with GCC to me, but I thought there was a workaround in gradle for that.

This is using the external native build instead of the experimental pluign.  It calls ndk-build directly.  Can ndk-build create response file?

Hi Dan,

I'm on a Mac running El Capitan and I'm using Clang.
