Coursier will search for your plugin with the following order on various classloaders:

1. Custom classloaders provided via the API (see FileCache.withClassLoaders)
2. Thread.currentThread().getContextClassLoader
3. The classloader that loaded coursier itself (more precisely, coursier.cache.CacheUrl.getClass.getClassLoader)
