Checkstyle rules for Google Java Style

Question

Is there a Checkstyle rule file with the Google Java Style?

Answer 1

The checkstyle team added it several days ago. Here it is : https://github.com/checkstyle/checkstyle/blob/master/src/main/resources/google_checks.xml

Answer 2

If you have a maven-project, you can easily integrate google_checks (you have to use at least maven-checkstyle-plugin version 2.17)

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-checkstyle-plugin</artifactId>
  <version>2.17</version>
  <configuration>
    <configLocation>google_checks.xml</configLocation>
  </configuration>
</plugin>

Executing checkstyle will use google_checks, e.g. do

mvn checkstyle:checkstyle

Version-background

Checkstyle-project integrates google_checks from version 6.9 on. Maven-checkstyle-plugin version 2.17. is the first one, which is released after checkstyle6.9 (actually it uses checkstyle6.11.2). So, maven-checkstyle-plugin2.17 is the first version of this plugin, which actually ships with google_checks and provides it without any other dependency.

Answer 3

The Google Summer of Code project to create such a file implies, that it doesn't exist yet.
