Maven checkstyle插件:向控制台打印警告

Question

我似乎无法弄清楚当我运行检查目标时如何让maven-checkstyle-plugin向控制台输出警告.

如果我配置为:

<module name="Checker">
    <module name="TreeWalker">
        <module name="NPathComplexity">
            <property name="max" value="5" />
            <property name="severity" value="warning" />
        </module>
    </module>
</module>

...我在控制台看不到任何东西,检查不会失败.如果我将严重性更改为错误,则检查失败.

有任何想法吗？我错过了什么吗？

插件配置如下

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-checkstyle-plugin</artifactId>
                <version>2.9.1</version>
                <configuration>
                    <includeTestSourceDirectory>true</includeTestSourceDirectory>
                    <logViolationsToConsole>true</logViolationsToConsole>
                    <configLocation>
                        rules.xml</configLocation>
                </configuration>
                <executions>
                    <execution>
                        <phase>compile</phase>
                        <goals>
                            <goal>check</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

Answer 1

我遇到了类似的问题.这个配置对我有用.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-checkstyle-plugin</artifactId>
    <version>2.9.1</version>
    <configuration>
        <consoleOutput>true</consoleOutput>
    </configuration>
    <executions>
        <execution>
           <id>checkstyle</id>
           <goals>
               <goal>checkstyle</goal>
           </goals>
           <phase>prepare-package</phase>
        </execution>
    </executions>
</plugin>

我假设您必须显式添加检查目标以将信息打印到控制台，如文档中所述。

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-checkstyle-plugin</artifactId>
    <version>2.9.1</version>
    <executions>
      <execute>
        <id>check</id>
        <goals><goal>check</goal></goals>
        <phase>prepare-package</phase>
      <execute>
    </executions>
  </plugin>

根据您调用 mvn 的方式，您需要更改执行检查的阶段。maven-checkstyle-plugin 的默认绑定是 verfiy 阶段。要么在执行块中给出显式阶段，要么只执行 mvn clean verify 并且可以省略阶段条目。
