Closure-compiler errors on current master

[reinhard]

I cloned the current master, ran npm install, bower install and gulp build -p and got following build errors and warnings:

Unfortunately I have no idea how to fix this problem.

Fixed. Update bower pls.

[reinhard]

Thanks for the quick response. Works now again for me.

I'm getting the same error, albeit in a project of my own. Was led here by google ;)

What was your fix? Upgrading/Downgrading closure? If yes, to which revision?

[steida]

bower cache clean, for some reason bower caches downloaded zip. Btw, in new ES6 Este, I don't use bower anymore. Closure Tools were moved into npm.
