I believe the problem here is that the execution is interrupted by some error (which isn't logged onto the console). Here's the gulp log:

Seems it stops before the generate: tasks are finished.

Happens also with PolymerElements/paper-elemnts but not PolymerElements/paper-icon-button

I also noticed that no java source code gets generated in the previously mentioned example, just resource folder (separate bug?).

alexwolfe/Buttons is not a polymer element, so you wont get any java source file since gwt-api-generator is only able to generate gwt wrappers for polymer elements following polymer projects conventions (import names, jsdoc, etc.). In a future though, it could parse other kind of projects like typescript definition files etc.

If you want to wrap a classic js library like alexwolfe/Buttons, you have first to create a new polymer element around the library, you might take a look to my wrapper for the pouchdb library: https://github.com/manolo/vaadin-pouchdb

PolymerElements/paper-elemnts is misspelled try either:

  $ gwt-api-generator --pom --package=PolymerElements/paper-elements
  or
  $ bower install PolymerElements/paper-elements
  $ gwt-api-generator --pom 

Note that pom.xml is only generated in the case there are elements to generate and there is no error
