I can't get the right path to bootstrap.css.min : I'm not able to get the correct css path

I have this code on my index.jsp head

    <link href="css/bootstrap.min.css" rel="stylesheet">
    <script src="javascript/jquery-3.1.1.min.js"></script>
    <script src="javascript/bootstrap.min.js"></script>
    <script src="javascript/angular.min.js"></script>

Note that if I use this:

    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

css shows correctly.

Here it's my [project buildpath][1]
