The Guava project contains several of Google's core libraries that we rely on in our Java-based projects: collections, caching, primitives support, concurrency libraries, common annotations, string processing, I/O, and so forth.
Requires JDK 1.6 or higher (as of 12.0).
The most recent release is Guava 19.0, released December 9, 2015.
To add a dependency on Guava using Maven, use the following:
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>19.0</version>
</dependency>
To add a dependency using Gradle:
dependencies {
compile 'com.google.guava:guava:19.0'
}
Snapshots of Guava built from the master
branch are available through Maven
using version 20.0-SNAPSHOT
. API documentation and diffs from version 19.0
are available here:
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 (e.g. using ProGuard).
Deprecated non-beta APIs will be removed two years after the release in which they are first deprecated. You must fix your references before this time. If you don't, any manner of breakage could result (you are not guaranteed a compilation error).
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.
We unit-test and benchmark the libraries using only OpenJDK 1.7 on
Linux. Some features, especially in com.google.common.io
, may not work
correctly in other environments.
