Why does my build fail with this error?

{android-sdk}/tools/ant/build.xml:479: SDK does not have any Build Tools installed

It

Answer 1

I installed Build Tools using SDK manager. They look installed, but they aren't. My {SDK}/build-tools folder is simply empty.

I just downloaded sdk from http://developer.android.com/sdk/index.html and moved android-4.2.2 folder in my build-tools folder.
