"rake" command using ruboto returns abort and permission denied

Question

I've recently decided to venture into android app development with ruboto. I installed the Android SDK with all the necessary development tools along with jruby, javac, ant, and ruboto. However, when I call the "rake" (ruby make) command, I get the following error:

morgan@ubuntu:~/quick_start$ rake
rake aborted!
Permission denied - /home/morgan/android/android-sdk-linux/platform-tools/dx
/home/morgan/quick_start/rakelib/ruboto.rake:27:in `initialize'
/home/morgan/quick_start/rakelib/ruboto.rake:27:in `open'
/home/morgan/quick_start/rakelib/ruboto.rake:27:in `<top (required)>'
/home/morgan/.rvm/gems/ruby-1.9.3-p385/bin/ruby_noexec_wrapper:14:in `eval'
/home/morgan/.rvm/gems/ruby-1.9.3-p385/bin/ruby_noexec_wrapper:14:in `<main>'

etc... It seems that the problem originates with the dx file within my android platform-tools... I was wondering if anyone has had any similar problems and how I would go about finding a solution so that I may run "rake" and generate a .apk file.

Answer 1

This bug was addressed recently by checking existence and file permissions of the dx command. It should work with the latest Ruboto release.
