Grunt hangs during build - gruntjs

Question

I am trying to run a grunt build and when it gets to the following:
Running tasks: compass:dist
Running "compass:dist" (compass) task
Verifying property compass.dist exists in config...OK
File: [no files]
Options: sassDir="src/assets/styles", cssDir=".tmp/styles", generatedImagesDir="dist/images/generated", imagesDir="src/assets/images", javascriptsDir="src/app", fontsDir="src/assets/styles/fonts", importPath="./bower_components", httpImagesPath="/images", httpGeneratedImagesPath="/images/generated", httpFontsPath="/styles/fonts", relativeAssets=false, assetCacheBuster=false, raw="Sass::Script::Number.precision = 10\r\n"
directory .tmp/styles
write .tmp/styles/main.css (4.122s)
Done, without errors.
Execution Time (2015-12-28 22:43:20 UTC)
loading tasks 9ms 0%
compass:dist 5.6s ■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■ 100%
Total 5.6s
It hangs there forever and never completes. I am not very good with Grunt and don't know how to begin troubleshooting this. Any advice/direction would be helpful.
EDIT: Here is my Gruntfile.js:

Answer 1

I had a similar issue an after a while I found that htmlmin was hanging because of an invalid tag on one html file.
Try to run:
grunt htmlmin --verbose
If that it is hanging you should see the name of the html file with problems.
After that try to find the issue, on your file, using one html validator.
