如果您查看错误，则表明第 80 行有问题。对于插件 maven-checkstyle-plugin，您在 XML 中有两个 configuration 标记。我会把它改成一个：

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-checkstyle-plugin</artifactId>
    <version>${maven-checkstyle-plugin.version}</version>
    <configuration>
      <testFailureIgnore>true</testFailureIgnore>
      <configLocation>com/github/ngeor/checkstyle.xml</configLocation>
      <includeTestSourceDirectory>true</includeTestSourceDirectory>
      <skip>${skipTests}</skip>
    </configuration>
    <dependencies>
      <dependency>
        <groupId>com.puppycrawl.tools</groupId>
        <artifactId>checkstyle</artifactId>
        <version>${checkstyle.version}</version>
      </dependency>
      <dependency>
        <groupId>com.github.ngeor</groupId>
        <artifactId>checkstyle-rules</artifactId>
        <version>${checkstyle-rules.version}</version>
      </dependency>
    </dependencies>
    <executions>
      <execution>
        <id>checkstyle</id>

        <goals>
          <goal>check</goal>
        </goals>
      </execution>
    </executions>
  </plugin>
