rake error on linux

[DHFE]

I tried to compile but i received this message

rake aborted!
Command failed with status (1): [ant debug...]
/home/superuser/quickstart/rakelib/ruboto.rake:949:in 'build_apk'
/home/superuser/quickstart/rakelib/ruboto.rake:540:in 'block in <top (required)>'
Task: TOP => default => debug => /home/superuser/quickstart/bin/Quickstart-debug.apk

after that I tried with:
sudo rake

and i received this message
rake aborted!
Errno::ENOENT: No such file or directory -adb version
/home/superuser/quickstart/rakelib/ruboto.rake:32:in '''
/home/superuser/quickstart/rakelib/ruboto.rake:32:in 'block in <top (required)>'

What i need to do to fix it?
