Field Details

PREFIX_PRIORITY

public static final 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 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.

HTTP_HEADERS

public static final String HTTP_HEADERS

The request headers to use for HTTP-based repository connectors. The headers are specified using a Map<String, String>, mapping a header name to its value. Besides this general key, clients may also specify headers for a specific remote repository by appending the suffix .<repoId> to this key when storing the headers map. The repository-specific headers map is supposed to be complete, i.e. is not merged with the general headers map.
