maven-checkstyle-plugin 不适用于 macOS 上的 google_checks.xml

Question

我有一个 Java / Maven 项目，我在家里用 Windows 构建并正确执行 checkstyle。 它使用的是内置规则集，但我也尝试了一个外部文件。

查看相同的代码/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 没有任何区别。

<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>

如果我那样运行它，它会在不进行任何检查的情况下完成：

mvn checkstyle:check -X

如果我对太阳检查进行相同的检查：

[..]

[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 似乎也有效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]

如日志所示，我在 macOS 10.13.3 和 Java 1.8.0_161 64 位上使用 Maven 3.5.2。

如何让 maven-checkstyle-plugin 在 macOS 上使用 google 规则集？

Answer 1

它确实运行它但不打印结果。 如下更改插件的配置。（启用控制台输出）

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

如果您想在检查样式发现警告时使构建失败，请取消注释 violationSeverity 行。 但它不打印发现的错误总数，只打印它发现的每个错误。
