java - Maven Jetty 插件 stopPort 和 stopKey 丢失或无效

Question

我正在学习Maven，遇到了一个问题。当我尝试对我的 webapp 执行 mvn clean install 时，我收到错误消息，指出参数 stopPort 和 stopKey 丢失或无效。这是 pom.xml 的样子:

    <plugin>
       <groupId>org.mortbay.jetty</groupId>
       <artifactId>maven-jetty-plugin</artifactId>
       <version>6.1.17</version>
       <executions>
         <execution>
            <id>start-jetty</id>
            <phase>pre-integration-test</phase>
            <goals>
              <goal>run</goal>
            </goals>
            <configuration>
              <scanIntervalSeconds>0</scanIntervalSeconds>
              <stopPort>9999</stopPort>
              <stopKey>foo</stopKey>
              <daemon>true</daemon>
            </configuration>
         </execution>
         <execution>
            <id>stop-jetty</id>
            <phase>post-integration-test</phase>
            <goals>
              <goal>stop</goal>
            </goals>
         </execution>
       </executions>
    </plugin>

知道是什么原因造成的吗？提前致谢。

Answer 1

问题是您只在run 目标中定义了stopPort 和stopKey 配置。此配置需要移至 execution 部分之外。

所以你的 pom 现在应该是:

<plugin>
   <groupId>org.mortbay.jetty</groupId>
   <artifactId>maven-jetty-plugin</artifactId>
   <version>6.1.17</version>
   <configuration>
       <scanIntervalSeconds>0</scanIntervalSeconds>
       <stopPort>9999</stopPort>
       <stopKey>foo</stopKey>
   </configuration>
   <executions>
     <execution>
        <id>start-jetty</id>
        <phase>pre-integration-test</phase>
        <goals>
          <goal>run</goal>
        </goals>
        <configuration>
          <daemon>true</daemon>
        </configuration>
     </execution>
     <execution>
        <id>stop-jetty</id>
        <phase>post-integration-test</phase>
        <goals>
          <goal>stop</goal>
        </goals>
     </execution>
   </executions>
</plugin>
