Has anyone faced this error with Concat (Loop Infinite)? http://pastebin.com/XQsYuqdc
GruntJs on windows Terminal: PowerShell
You are defining a task which will run itself, entering an infinite loop.
This is the problem line:
grunt.registerTask( 'concat', [ 'concat' ] );
This will also be a problem:
grunt.registerTask( 'copy', [ 'copy' ] );
In both of those cases, there's no reason to define custom tasks to run the grunt tasks (I suggest removing those two lines, and then things will work).
You could define a custom task to run both of those tasks though, something like:
grunt.registerTask( 'build', [ 'concat', 'copy' ] );
