How to undo the “ignore” part of the bower.json dependency file?

I would like to use https://github.com/MrRio/jsPDF in my ember project. I wanted to import jsPDF as a dependency, so I started this way:

bower install git@github.com:MrRio/jsPDF.git --save

Unfortunately, I cannot install files from the plugins directory because the directory is "plugins/*"ignored in the bower.json file. I tried to redefine it this way, but to no avail.

  "overrides": {
    "jspdf": {
      "ignore": [
        "**/.*",
        "libs",
        "CNAME",
        "jspdf.js",
        "examples/jspdf.PLUGINTEMPLATE.js",
        "todo.txt",
        "wscript.py",
        "build.sh",
        "test",
        "tools"
      ]
    }
  }

could you help me?
