如何修复maven检查样式错误

Question

目前我只是尝试下载和构建以使Netty源代码工作.但是当我尝试mvn eclipse:eclipse在源文件夹中运行该命令时.我说错了

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-checkstyle-plugin:2.10:check (check-style) on project netty-common: Failed during checkstyle execu

验证代码netty-common项目时,ch​​eckstyle插件是错误的.

我不熟悉这个插件.我想知道我是否可以通过从pom.xml(在)中删除配置来忽略它.如下.

<plugin>
        <artifactId>maven-checkstyle-plugin</artifactId>
        <version>2.10</version>
        <executions>
          <execution>
            <id>check-style</id>
            <goals>
              <goal>check</goal>
            </goals>
            <phase>validate</phase>
            <configuration>
              <consoleOutput>true</consoleOutput>
              <logViolationsToConsole>true</logViolationsToConsole>
              <failsOnError>true</failsOnError>
              <failOnViolation>true</failOnViolation>
              <configLocation>io/netty/checkstyle.xml</configLocation>
              <includeTestSourceDirectory>true</includeTestSourceDirectory>
            </configuration>
          </execution>
        </executions>
        <dependencies>
          <dependency>
            <groupId>${project.groupId}</groupId>
            <artifactId>netty-build</artifactId>
            <version>21</version>
          </dependency>
        </dependencies>
      </plugin>

任何的想法 ？谢谢.

Answer 1

使用跳过检查样式执行

-Dcheckstyle.skip

防爆

mvn [YOUR_COMMAND] -Dcheckstyle.skip

Answer 2

CheckStyle是maven的一个模块,用于检查代码的样式,例如制表符而不是空格.Netty正在使用它来防止基本的格式错误.

如果您计划为Netty做出贡献,则不应删除该插件,因为这可能意味着您的补丁永远不会应用.

如果您只是玩游戏,则可以自由删除该插件,因为它的唯一目的是验证安装,而不是从安装中更改内容.

如果您选择保留它,你应该看看在输出日志,看看有什么错误是它检测,快速修复的错误,看到这个答案由马修·法威尔.

1. 右键单击Package Explorer中的java文件或其他,然后选择"Apply Checkstyle Corrections".
2. 单击问题视图中的错误,然后选择"快速修复".这纠正了问题.
