当使用checkstyle-maven-plugin3.1.2时，我可以在这样的配置中定义一个编码元素：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-checkstyle-plugin</artifactId>
    <version>${maven-checkstyle-plugin.version}</version>
    <dependencies>
      <dependency>
        <groupId>com.puppycrawl.tools</groupId>
        <artifactId>checkstyle</artifactId>
        <version>${checkstyle.version}</version>
      </dependency>
    </dependencies>
    <configuration>
      <configLocation>checkstyle.xml</configLocation>
      <encoding>UTF-8</encoding>
      <consoleOutput>true</consoleOutput>
      <failsOnError>true</failsOnError>
      <failOnViolation>true</failOnViolation>
      <violationSeverity>warning</violationSeverity>
      <linkXRef>false</linkXRef>
    </configuration>
    <executions>
      <execution>
        <id>validate</id>
        <phase>validate</phase>
        <goals>
          <goal>check</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

更新到版本3.2.2后，我得到提示“* 此处不允许使用元素编码 *”。我试着在文档中查找，但到目前为止还没有找到任何东西。我在哪里定义编码呢？
我尝试使用spring-boot-starter-parent版本2.7.11使用Maven 3.8.1和3.9.2，编译到Java版本11。
我删除了所有其他插件，依赖项......当使用maven-checkstyle.plugin版本3.2.2时，IntelliJ仍然抱怨该元素，而3.1.2版本可以正常工作。

之后，我用这个POM在IntelliJ中创建了一个全新的Maven项目，仍然收到IntelliJ的警告：
