Annotation Type ExternalLib

@Target(value=TYPE)
 @Retention(value=RUNTIME)
 @Documented
 @Repeatable(value=ExternalLibs.class)
public @interface ExternalLib

Specifies that the annotated element depends on a library which is not packaged with the extension.

This annotation is intended to be used in classes which represent the extension, a configuration or a connection provider.

When the dependency is needed extension wide, then this annotation should be used at the extension level. If it's only needed when using a particular configuration, then it should be used at the config level. Finally, if it's needed only for establishing connections, then it should be used on a connection provider. Notice that you can have a mix of any of these options, since an extension can depend on many external libraries in different places. An example would be the Database connector, which has different ConnectionProvider for connecting to different types of databases, each one requiring a different JDBC driver.

This annotation is repeatable, which means that any annotated component can depend on many external libraries.
