- Field Detail
  - PREFIX_PRIORITY
```
public static final java.lang.String PREFIX_PRIORITY
```
    The prefix for properties that control the priority of pluggable extensions like transporters. For example, for an extension with the fully qualified class name "org.eclipse.MyExtensionFactory", the configuration properties "aether.priority.org.eclipse.MyExtensionFactory", "aether.priority.MyExtensionFactory" and "aether.priority.MyExtension" will be consulted for the priority, in that order (obviously, the last key is only tried if the class name ends with "Factory"). The corresponding value is a float and the special value Float.NaN or "NaN" (case-sensitive) can be used to disable the extension.

    Constant Field Values
  - IMPLICIT_PRIORITIES
```
public static final java.lang.String IMPLICIT_PRIORITIES
```
    A flag indicating whether the priorities of pluggable extensions are implicitly given by their iteration order such that the first extension has the highest priority. If set, an extension's built-in priority as well as any corresponding aether.priority.* configuration properties are ignored when searching for a suitable implementation among the available extensions. This priority mode is meant for cases where the application will present/inject extensions in the desired search order.
