java maven netty

目前，我只是尝试下载和构建以使Netty源代码正常工作。但是当我尝试在源文件夹中运行该命令时。我收到一个错误说mvn eclipse:eclipse

[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

这是校验样式插件在验证代码项目时的错误。netty-common

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。如下图所示。

<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>

任何想法？谢谢。

答案 1

跳过检查样式执行使用

-Dcheckstyle.skip

前任

mvn [YOUR_COMMAND] -Dcheckstyle.skip

答案 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。

如果您打算为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。

如果您只是使用，则可以自由删除该插件，因为它的唯一目的是验证安装，而不是更改安装中的内容。

如果你选择保留它，你应该在输出日志中查看它检测到的错误，以快速修复错误，请参阅Matthew Farwell的这个答案。

右键单击包资源管理器中的java文件或其他任何内容，然后选择“应用检查样式更正”。

单击问题视图中的错误，然后选择“快速修复”。这样可以纠正问题。
