I generated a Fresh Webapp with Yeoman, and I ran Grunt Build --verbose. Warning below
Running "useminPrepare:html" (useminPrepare) task
Verifying property useminPrepare.html exists in config...OK
Files: app/index.html -> html
Options: dest="dist"
Going through app/index.html to update the config
Looking for build script HTML comment blocks
Warning: An error occurred while processing a template (Unexpected token )). Use --force to continue.
Aborted due to warnings.
here is my /Gruntfile.js
// Reads HTML for usemin blocks to enable smart builds that automatically
// concat, minify and revision files. Creates configurations in memory so
// additional tasks can operate on them
useminPrepare: {
options: {
dest: '<%= config.dist %>'
},
html: '<%= config.app %>/index.html'
},
// Performs rewrites based on rev and the useminPrepare configuration
usemin: {
options: {
assetsDirs: [
'<%= config.dist %>',
'<%= config.dist %>/images',
'<%= config.dist %>/styles'
]
},
html: ['<%= config.dist %>/{,*/}*.html'],
css: ['<%= config.dist %>/styles/{,*/}*.css']
},

There are 17 ) in my index.html, and they all have an opening (, I couldn't find the problem, and I don't understand it, since I didn't change anything. I was just trying to see if everything worked.
If that's your whole Gruntfile, then I'm not sure what the problem is. But if there's an imagemin task, check and see if the templates have an extra %. See: https://stackoverflow.com/a/35090387/5858382
