Looks like Bower is aware of this issue : https://twitter.com/bower/status/487704111832252417
Let me check if I can do something

Hi,

the same failure output  "[INFO] Fatal error: Arguments to path.join must be strings" have been noticed also when building liveoak 'master'. I suspect some change on the nodes tools broke builds.. :(

Hi,

since Friday, all in a sudden, the node.js part of the build (triggered by the frontend plugin inside the 'server' module) is failing on different ways.

Extremely odd: the 0.11.0 tag is effected as well. The release (on maven central) is good, but ATM we are not able to build the source on the 0.11.0 tag :-(

Oh, yeah, Travis-CI notice the broken build as well ;-) and thankfully abstractj put in a PR to have a temporary fix for the build failure: https://github.com/aerogear/aerogear-unifiedpush-server/pull/293

Thanks Bruno!

Yesterday Bruno, Villiam and Luke looked at this already, and they noticed a failure like this:

[INFO] --- frontend-maven-plugin:0.0.15:npm (npm install) @ unifiedpush-server ---

Note: "grunt-cli" IS installed, even globally. If I am correct, at the moment we are not 100% sure what the "Fatal error: Arguments to path.join must be strings" really means...

On my machine, I noticed the npm stuff downloads half of the internet, but gets stuck in the middle:

Now, after more than one hour of 'waiting', I cancled the build, resulting in:

This is more a FYI on what's going on - I will file a JIRA ticket for that;

PS: According to yesterday's IRC discussions, a manual `grunt server does work, so development is notdirectly effected
