即使將“failsOnError”設置為“true”，Maven Checkstyle 插件在構建期間也不會失敗

Question

我的項目強制執行嚴格的樣式，因此我將maven-checkstyle-plugin作為構建的一部分運行。

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-checkstyle-plugin</artifactId>
  <version>${maven-checkstyle.version}</version> // 3.0.0
  <executions>
    <execution>
      <id>checkstyle</id>
      <phase>validate</phase>
      <goals>
        <goal>check</goal>
      </goals>
      <configuration>
        <configLocation>google_checks.xml</configLocation>
        <encoding>UTF-8</encoding>
        <consoleOutput>true</consoleOutput>
        <failsOnError>true</failsOnError>
      </configuration>
    </execution>
  </executions>
</plugin>

當我運行構建時，我看到插件正在運行並檢查樣式，但是當出現檢查樣式問題時它應該會失敗，因為我設置了true標志。

它繼續運行並且構建成功的任何原因？

閱讀日志：

[WARN] /Users/jeeves/git/jeeves/demo/src/main/java/com/demo/api/routes/UserRoutes.java:9:57: Parameter name 'BASE_PATH' must match pattern '^[a-z][a-z0-9][a-zA-Z0-9]*$'. [ParameterName]
[WARN] /Users/jeeves/git/jeeves/demo/src/main/java/com/demo/api/routes/UserRoutes.java:13: Line is longer than 100 characters (found 102). [LineLength]
Audit done.

這些是警告而不是錯誤，所以<failsOnError>true</failsOnError>不會觸發。

將以下行添加到configuration中應該會改變行為：

<violationSeverity>warning</violationSeverity>
<failOnViolation>true</failOnViolation>        <!-- defaults as true, can be omitted -->

請參閱maven-checkstyle-plugin-2.16的文檔：

• violationSeverity定義違規的嚴重程度。
• failOnViolation在發生違規時觸發“失敗”事件。
