Scans the source of a and finds all loadable classes and resources.
Warning: Current limitations:
- Looks only for files and JARs in URLs available from instances or the .
- Only understands file: URLs.
In the case of directory classloaders, symlinks are supported but cycles are not traversed. This guarantees discovery of each unique loadable resource. However, not all possible aliases for resources on cyclic paths will be listed.

`static ClassPath`	`classloader)`	Returns a `ClassPath` representing all classes and resources loadable from `classloader` and its ancestor class loaders.
`ImmutableSet<ClassPath.ClassInfo>`	`getAllClasses()`	Returns all classes loadable from the current class path.
`ImmutableSet<ClassPath.ResourceInfo>`	`getResources()`	Returns all resources loadable from the current class path, including the class files of all loadable classes but excluding the "META-INF/MANIFEST.MF" file.

public static  classloader)
                      throws 
```
    Returns a ClassPath representing all classes and resources loadable from classloader and its ancestor class loaders.
    Warning: ClassPath can find classes and resources only from:
    
    instances' file: URLs
    the . To search the system class loader even when it is not a (as in Java 9), ClassPath searches the files from the java.class.path system property.
    Throws:
    
    - if the attempt to read class path resources (jar files or directories) failed.
  - getResources
```
public ImmutableSet<ClassPath.ResourceInfo> getResources()
```
    Returns all resources loadable from the current class path, including the class files of all loadable classes but excluding the "META-INF/MANIFEST.MF" file.
  - getAllClasses
```
public ImmutableSet<ClassPath.ClassInfo> getAllClasses()
```
    Returns all classes loadable from the current class path.

  - getTopLevelClasses
```
public ImmutableSet<ClassPath.ClassInfo> getTopLevelClasses()
```
    Returns all top level classes loadable from the current class path. Note that "top-level-ness" is determined heuristically by class name (see ClassPath.ClassInfo.isTopLevel()).
  - getTopLevelClasses
```
public  packageName)
```
    Returns all top level classes whose package name is packageName.
  - getTopLevelClassesRecursive
```
public  packageName)
```
    Returns all top level classes whose package name is packageName or starts with packageName followed by a '.'.
