I agree with Matt that the NoClassDefFoundError is the problem. That class should be part of tools.jar.

Be sure that your PATH and JAVA_HOME are set correctly, and that you're not somehow pointing at a JRE, which won't have toos.jar. You might want to try building from the command line instead of through IntelliJ so that it's easy to change the environment variables and see if the error message changes.
