This project provides a means to locate assets within WebJars.

WebJarAssetLocator locator = new WebJarAssetLocator();
String fullPathToRequirejs = locator.getFullPath("require.js");

WebJarAssetLocator locator = new WebJarAssetLocator();
Set<String> fullPathsOfAssets = locator.listAssets("/multiple/1.0.0");

The locator can also be configured with the class loaders that it should use for looking up resources and filter the types of resources that should be included for searching. Please visit the source code for more information.
