Because you usually write code very fast, you can sometimes made mistakes.
To prevent some stupid errors, folks from Google write the error prone compiler.
Have a look at the various detected patterns (yeah definitely more interesting than checkstyle :P )
Kudos to Alex Eagle for the contribution!.
The configuration to use it:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<compilerId>javac-with-errorprone</compilerId>
<forceJavacCompilerUse>true</forceJavacCompilerUse>
</configuration>
<dependencies>
<dependency>
<groupId>org.codehaus.plexus</groupId>
<artifactId>plexus-compiler-javac-errorprone</artifactId>
<version>2.3</version>
</dependency>
<!-- NOTE this one will not be needed when plexus-compiler-javac-errorprone and error-prone will be released -->
<dependency>
<groupId>org.codehaus.plexus</groupId>
<artifactId>plexus-compiler-javac</artifactId>
<version>2.3</version>
</dependency>
</dependencies>
</plugin>
Feel free to test, I hope we will be able to have released versions of those artifacts soon.
