创建一个单独的Maven项目，它只包含Checkstyle配置。在我的例子中，我将此项目称为checkstyle-config，它包含以下内容：

checkstyle-config/src/main/resources/checkstyle.config.xml
checkstyle-config/src/main/resources/checkstyle.suppressions.xml
checkstyle-config/pom.xml

这个项目的POM文件很简单：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.totaalsoftware.incidentmanager</groupId>
  <artifactId>checkstyle-config</artifactId>
  <version>2.0.0-SNAPSHOT</version>
</project>

构建它，以便安装它。然后将其用作执行Checkstyle的依赖项,例如：

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-checkstyle-plugin</artifactId>
    <executions>
      <execution>
        <goals>
          <goal>check</goal>
        </goals>
      </execution>
    </executions>
    <dependencies>
      <dependency>
        <groupId>com.totaalsoftware.incidentmanager</groupId>
        <artifactId>checkstyle-config</artifactId>
        <version>2.0.0-SNAPSHOT</version>
      </dependency>
    </dependencies>
    <configuration>
      <configLocation>checkstyle.config.xml</configLocation>
      <suppressionsLocation>checkstyle.suppressions.xml</suppressionsLocation>

      ... other configuration ...

    </configuration>
  </plugin>
