If you would like to use the WebJars Library in your Project, visit WebJars and check out the right dependency for your requirements. You can make use of the Search/Filter Box or browse through the hole page.
If you want to use Bootstrap in your project, just add the following dependencies to your pom.xml (if you build with maven)
org.webjars bootstrap 3.3.7 org.webjars jquery 3.1.1-1
Then you can refer to bootstrap and jquery from a folder called „webjars“
Hope that helps.
