Grunt-wiredep done without errors but doesn't inject dependencies - php

Question

I'm trying to connect wiredep with my project, with no success. I have the bower_components and bower.json inside assets/, and the gruntfile.js in the root directory. Here's the relevant gruntfile:
wiredep: {
target: {
src: [
'grunt-test.html',
'application/views/inc/inc_scripts.php',
'application/views/inc/inc_head.php'
],
directory: 'assets/bower_components',
bowerJson: 'assets/bower.json',
fileTypes: {
php: {
block: /(([\s\t]*)<!--\s*bower:*(\S*)\s*-->)(\n|\r|.)*?(<!--\s*endbower\s*-->)/gi,
detect: {
js: /<script.*src=['"](.+)['"]>/gi,
css: /<link.*href=['"](.+)['"]/gi
},
replace: {
js: '<script src="{{filePath}}"></script>', // <-- Change this line
css: '<link rel="stylesheet" href="{{filePath}}" />'
}
},
html: {
block: /(([\s\t]*)<!--\s*bower:*(\S*)\s*-->)(\n|\r|.)*?(<!--\s*endbower\s*-->)/gi,
detect: {
js: /<script.*src=['"](.+)['"]>/gi,
css: /<link.*href=['"](.+)['"]/gi
},
replace: {
js: '<script src="{{filePath}}"></script>', // <-- Change this line
css: '<link rel="stylesheet" href="{{filePath}}" />'
}
}
}
}
}
Then I run grunt wiredep --verbose and get the following output:
Running "wiredep" task
Running "wiredep:target" (wiredep) task
Verifying property wiredep.target exists in config...OK
Files: grunt-test.html, application/views/inc/inc_scripts.php, application/views
/inc/inc_head.php
Verifying property wiredep.target.src exists in config...OK
Options: src=["grunt-test.html","application/views/inc/inc_scripts.php","application/views/inc/inc_head.php"], directory="assets/bower_components", bowerJson="a ssets/bower.json",fileTypes={"php":{"block":{},"detect":{"js":{},"css":{}},"replace":{"js":"<script src=\"{{filePath}}\"></script>","css":"<link rel=\"stylesheet\" href=\"{{filePath}}\" />"}},"html":{"block":{},"detect":{"js":{},"css":{}},"replace":{"js":"<script src=\"{{filePath}}\"></script>","css":"<link rel=\"stylesheet\" href=\"{{filePath}}\" />"}}}
Done, without errors.
But nothing happens. I've made sure that I'm using the right tags and even tried adding an HTML file (grunt-test.html) to make sure it's not a filetype thing, but I'm at a loss right now.
What do you guys see?
Thanks in advance.
