Answer: 

bower.json:

 { "name": "xxxxxxx", "version": "1.0.0", "dependencies": { "angular": ">=1.2.*", "json3": "~3.3.1", "es5-shim": "~3.0.1", "jquery": "~1.11.0", "bootstrap": "~3.1.1", "angular-resource": ">=1.2.*", "angular-cookies": ">=1.2.*", "angular-sanitize": ">=1.2.*", "angular-bootstrap": "~0.11.0", "font-awesome": ">=4.1.0", "lodash": "~2.4.1", "angular-ui-router": "~0.2.10", "angular-google-maps": "~2.1.0", "angular-animate": "~1.3.15", "ng-table": "~0.5.4", "angular-touch": "~1.3.15" }, "devDependencies": { "angular-mocks": ">=1.2.*", "angular-scenario": ">=1.2.*" } } 

Answer 1

Some of your dependencies are stated in sufficient detail depending on the specific version of angular. In most cases, you can use the top version without impact.

add

 "resolutions" : { "angular" : "1.3.15", } 

to your bower file to force the angular version

In addition, you should clean your bower angular files. You are requesting ng-animate 1.3.15+ and angular 1.2+. All versions of the angular module should be the same for convenience.
