Error while running migrator/recast

[awaer]

After files are moved/copied, I am seeing these errors output to console and it is unclear what steps need to be taken in order to resolve the problem.

It seems this issue was caused by the presence of jQuery in app/scripts/vendor while running ember-cli-migrator. Removing that file prevented the error and allowed the migrator script to terminate successfully. I was able to trace it by adding a console.log to /usr/local/lib/node_modules/ember-cli-migrator/lib/ember-migrator.js:160 before the call to self.processFile(self.splitFiles[key])

How come the migrator was running on app/scripts/vendor, usually you just run it against the ember code

[awaer]

@igorT Is there a way to exclude? Our Ember application files/folders are in app/scripts, which also contains vendor scripts in app/scripts/vendor. The migrator seems to run over everything contained in the source directory. I don't see any way to avoid this.

Usually people put libraries outside their ember source code, one level deeper

For what it's worth, I ran into the same issue. For it my paths looked like 'app/js/libs/' and libs contained jquery, ember, and a few other things.

I'm pretty sure that's the layout the ember website encouraged me to use back when I first setup my project, which was around ember-1.0.4 or so.

Also, I had to have it ignore the .git directory, which I found odd since it has special support for git.
