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 by any library that wants to be compatible with Android.
These flavors are specified in the Maven version field as either `33.2.1-jre` or
`33.2.1-android`. For more about depending on Guava, see
[using Guava in your build].

[[sec:precedence]]
== Toolchain installations precedence

Gradle will sort all the JDK/JRE installations matching the toolchain specification of the build and will pick the first one.
Sorting is done based on the following rules:

. the installation currently running Gradle is preferred over any other
. JDK installations are preferred over JRE ones
