Open source authentication client library for Java.

See the official guide for ways to authenticate to Google Cloud and for more information about the Google Auth Library.

See the API Documentation to see the Javadocs for Google Auth Library.

This library follows Semantic Versioning, but with some additional qualifications:

1. Components marked with @ObsoleteApi are stable for usage in the current major version, but will be marked with @Deprecated in a future major version. NOTE: We reserve the right to mark anything as @Deprecated and introduce breaking changes in a minor version to fix any critical bugs and vulnerabilities.

2. Components marked with @InternalApi are technically public, but are only public for technical reasons, because of the limitations of Java's access modifiers. For the purposes of semver, they should be considered private.

3. Components marked with @InternalExtensionOnly are stable for usage, but not for extension. Thus, methods will not be removed from interfaces marked with this annotation, but methods can be added, thus breaking any code implementing the interface. See the javadocs for more details on other consequences of this annotation.

4. Components marked with @BetaApi are considered to be "0.x" features inside a "1.x" library. This means they can change between minor and patch releases in incompatible ways. These features should not be used by any library "B" that itself has consumers, unless the components of library B that use @BetaApi features are also marked with @BetaApi. Features marked as @BetaApi are on a path to eventually become "1.x" features with the marker removed.

Contributions to this library are always welcome and highly encouraged.
