Guava: Google Core Libraries for Java

Guava is a set of core libraries that includes new collection types (such as
multimap and multiset), immutable collections, a graph library, and utilities
for concurrency, I/O, hashing, primitives, strings, and more!

Guava comes in two flavors.

The JRE flavor requires JDK 1.8 or higher.
If you need support for JDK 1.7 or Android, use the Android flavor. You can
find the Android Guava source in the android directory.

Adding Guava to your build

Guava's Maven group ID is com.google.guava and its artifact ID is guava.
Guava provides two different "flavors": one for use on a (Java 8+) JRE and one
for use on Android or Java 7 or by any library that wants to be compatible with
either of those. These flavors are specified in the Maven version field as
either 28.2-jre or 28.2-android. For more about depending on Guava, see
using Guava in your build.

To add a dependency on Guava using Maven, use the following:

<dependency>
  <groupId>com.google.guava</groupId>
  <artifactId>guava</artifactId>
  <version>28.2-jre</version>
  <!-- or, for Android: -->
  <version>28.2-android</version>
</dependency>

To add a dependency using Gradle:

dependencies {
  // Pick one:

  // 1. Use Guava in your implementation only:
  implementation("com.google.guava:guava:28.2-jre")

  // 2. Use Guava types in your public API:
  api("com.google.guava:guava:28.2-jre")

  // 3. Android - Use Guava in your implementation only:
  implementation("com.google.guava:guava:28.2-android")

  // 4. Android - Use Guava types in your public API:
  api("com.google.guava:guava:28.2-android")
}

For more information on when to use api and when to use implementation,
consult the
Gradle documentation on API and implementation separation.

Snapshots

Snapshots of Guava built from the master branch are available through Maven
using version HEAD-jre-SNAPSHOT, or HEAD-android-SNAPSHOT for the Android
flavor.

IMPORTANT WARNINGS

APIs marked with the @Beta annotation at the class or method level are
subject to change. They can be modified in any way, or even removed, at any
time. If your code is a library itself (i.e. it is used on the CLASSPATH of
users outside your own control), you should not use beta APIs, unless you
repackage them. If your code is a library, we strongly recommend using
the Guava Beta Checker to ensure that you do not use any @Beta APIs!
APIs without @Beta will remain binary-compatible for the indefinite
future. (Previously, we sometimes removed such APIs after a deprecation
period. The last release to remove non-@Beta APIs was Guava 21.0.) Even
@Deprecated APIs will remain (again, unless they are @Beta). We have no
plans to start removing things again, but officially, we're leaving our
options open in case of surprises (like, say, a serious security problem).
Guava has one dependency that is needed at runtime:
com.google.guava:failureaccess:1.0.1
Serialized forms of ALL objects are subject to change unless noted
otherwise. Do not persist these and assume they can be read by a future
version of the library.
Our classes are not designed to protect against a malicious caller. You
should not use them for communication between trusted and untrusted code.
For the mainline flavor, we unit-test the libraries using only OpenJDK 1.8
on Linux. Some features, especially in com.google.common.io, may not work
correctly in other environments. For the Android flavor, our unit tests run
on API level 15 (Ice Cream Sandwich).
