Maven 目标未附加到阶段

Question

我正在尝试运行一些 Selenium 测试，但是无法将 Jetty 的启动附加到 Maven 的预集成测试阶段。所以我试图调查这个问题，似乎一般来说 Maven 没有在我指定的阶段执行我的目标。

我找到了 this 示例并复制了它。我创建了一个插件，当我明确调用它时它工作正常。但是当我尝试将它附加到验证阶段并且运行 mvn validate 我没有看到 "Hi there!!!" 输出。它只是向我展示构建成功而没有调用 howdy-world 目标：/（这与我的码头不在集成测试阶段开始一致）

当验证阶段通过后，我如何实现这个目标运行？

这是我的 pom.xml：

你必须这样做：

<project
  xmlns="http://maven.apache.org/POM/4.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <build>
    <pluginManagement>
      <plugins>
        <plugins>
          <plugin>
            <groupId>org.eclipse.m2e</groupId>
            <artifactId>lifecycle-mapping</artifactId>
            <version>1.0.0</version>
            <configuration>
              <lifecycleMappingMetadata>
                <pluginExecutions>
                  <pluginExecution>
                    <pluginExecutionFilter>
                      <groupId>com.maventest</groupId>
                      <artifactId>maven-howdy-plugin</artifactId>
                      <versionRange>[1.0.0,)</versionRange>
                      <goals>
                        <goal>howdy-world</goal>
                      </goals>
                    </pluginExecutionFilter>
                    <action>
                      <ignore />
                    </action>
                  </pluginExecution>
                </pluginExecutions>
              </lifecycleMappingMetadata>
            </configuration>
          </plugin>
          <plugin>
            <groupId>com.maventest</groupId>
            <artifactId>maven-howdy-plugin</artifactId>
            <version>1.0-SNAPSHOT</version>
          </plugin>
        </plugins>
    </pluginManagement>
    <!-- The following will really execute the plugin -->
    <plugins>
      <plugin>
        <groupId>com.maventest</groupId>
        <artifactId>maven-howdy-plugin</artifactId>
        <executions>
          <execution>
            <goals>
              <goal>howdy-world</goal>
            </goals>
            <phase>validate</phase>
          </execution>
        </executions>
      </plugin>
    </plugins>

  </build>
</project>

pluginManagement 部分仅用于定义插件的版本和配置，但它不会真正在生命周期内执行这些插件。
