title: how to extract used licenses from a java project
body: <p>As many other people I used several opensource libraries in my project. Most of them are used as JAR files. I now would like to create a list of the used licenses (e.g. Apache, GPL, LGPL, Mozilla Public License,...)
  some jars contain a license.txt but most of them not. Could you please recommend me a software or method, how i could extract such "used licenses"-information out of my java project?
  Thanking you very much in advance for helping me</p>
