Example 16 with ClassGraph

use of io.github.classgraph.ClassGraph in project beam by apache.

the class ClasspathScanningResourcesDetectorTest method shouldStillDetectResourcesEvenIfClassloaderIsUseless.

/*
   * ClassGraph library that is used in the tested algorithm can still detect resources from
   * "java.class.path" env variable. Even in case the classloader that is passed is of no use we
   * will still be able to detect and load resource paths from the env variable.
