java - checkstyle 使用的默认规则是什么？

Question

如果我没有定义 checkstyle 配置，则默认执行几个 checkstyle 规则，是否有 checkstyle 使用的默认规则列表？

这就是我的 Maven 配置的样子:

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-checkstyle-plugin</artifactId>
                <version>3.1.0</version>
                <configuration>
                    <failOnViolation>true</failOnViolation>
                    <consoleOutput>true</consoleOutput>
                    <logViolationsToConsole>true</logViolationsToConsole>
                </configuration>
                <executions>
                    <execution>
                        <id>validate</id>
                        <phase>validate</phase>
                        <goals>
                            <goal>check</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

默认配置使用 sun_checks.xml 中预定义的规则集“Sun Microsystems Definition”，请参阅 Maven Checkstyle Plugin docs :

There are 2 predefined Checkstyle configuration definitions that ship with the Checkstyle Plugin, the Sun Microsystems Definition is selected by default.

• sun_checks.xml - Sun Microsystems Definition (default).
• google_checks.xml - Google Definition.

规则集的内容可以在 Checkstyle's GitHub repository 找到.
