maven-checkstyle-plugin无法在macOS上使用google_checks.xml

Question

我有一个Java / Maven项目，我在家里用Windows构建并正在执行checkstyle。它使用内置规则集，但我也尝试了外部文件。

检查相同的代码/ pom.xml它似乎不适用于macOS。奇怪的是，如果我使用sun_checks.xml它工作正常。使用8.8并没有什么区别。

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-checkstyle-plugin</artifactId>
  <version>3.0.0</version>
  <dependencies>
    <dependency>
      <groupId>com.puppycrawl.tools</groupId>
      <artifactId>checkstyle</artifactId>
      <version>8.7</version>
    </dependency>
  </dependencies>
  <configuration>
    <encoding>UTF-8</encoding>
    <configLocation>google_checks.xml</configLocation>
  </configuration>
</plugin>

如果我像那样运行它，它将完成而不进行任何检查：

mvn checkstyle:check -X

如果我用太阳检查运行相同：

[INFO] There are 7 errors reported by Checkstyle 8.7 with sun_checks.xml ruleset.
[ERROR] src/main/java/com/udoheld/Test.java:[0] (javadoc) JavadocPackage: Missing package-info.java file.

在不使用maven的情况下在命令行上尝试checkstyle似乎也能正常工作java -jar ~/Downloads/checkstyle-8.8/checkstyle-8.8-all.jar -c ../checkstyle-google.xml *：

Starting audit...
[WARN] /gdev/git/test/src/main/java/com/udoheld/Test.java:18: Comment has incorrect indentation level 4, expected is 6, indentation should be the same level as line 19. [CommentsIndentation]

正如日志显示我在macOS 10.13.3上使用Maven 3.5.2和Java 1.8.0_161 64位。

如何在macOS上使用maven-checkstyle-plugin处理google规则集？

Answer 1

它实际上运行它但不打印结果。像下面一样更改插件的配置。（启用控制台输出）

     <configuration>
        <!-- <violationSeverity>warning</violationSeverity> -->
        <consoleOutput>true</consoleOutput>
        <encoding>UTF-8</encoding>
        <configLocation>google_checks.xml</configLocation>
      </configuration>

如果要在检查样式发现警告时使构建失败，请取消注释violationSeverity行。但它不会打印找到的错误总数，只打印它找到的每个错误。
