Maven Cargo 不会停止容器

Question

我有一个 Maven 项目，我想在其中使用 Cargo-Maven-Plugin (1.1.1) 来启动和停止 tomcat 服务器来运行集成测试。

<plugin>
<groupId>org.codehaus.cargo</groupId>
<artifactId>cargo-maven2-plugin</artifactId>
<version>1.1.1</version>
<executions>
    <execution>
        <id>start-container</id>
        <phase>pre-integration-test</phase>
        <goals>
            <goal>start</goal>
        </goals>
    </execution>
    <execution>
        <id>stop-container</id>
        <phase>post-integration-test</phase>
        <goals>
            <goal>stop</goal>
        </goals>
    </execution>
</executions>
<configuration>                 
    <container>                 
    <type>installed</type>
    <containerId>tomcat6x</containerId>
    <zipUrlInstaller>
        <url>http://archive.apache.org/dist/tomcat/tomcat-6/v6.0.32/bin/apache-tomcat-6.0.32.zip</url>
    </zipUrlInstaller>
</container>    
</configuration>
</plugin>

服务器的启动工作正常，但停止总是失败。

我已经用几个项目对其进行了测试，至少添加了一个空项目（注意除了 web.xml ），但结果始终相同。我测试了 tomcat6、tomcat7 甚至嵌入式 Jetty6 和 7，但总是出现相同的异常。我在启动和停止之间添加了 5 秒的延迟（通过集成测试），但这没有帮助。

当我查看日志文件和正在运行的进程时，似乎tomcat已停止，但cargo没有注意到它。

24.06.2011 17:38:07 org.apache.catalina.startup.Catalina start
INFO: Server startup in 694 ms
24.06.2011 17:38:07 org.apache.coyote.http11.Http11Protocol pause
INFO: Pausing Coyote HTTP/1.1 on http-8080
24.06.2011 17:38:08 org.apache.catalina.core.StandardService stop
INFO: Stopping service Catalina
24.06.2011 17:38:08 org.apache.coyote.http11.Http11Protocol destroy
INFO: Stopping Coyote HTTP/1.1 on http-8080

所以我的问题是：

• 我做错了什么吗？
• 这是一个错误吗？
• 有什么解决方法吗？

Answer 1

可能有其他东西正在侦听您计算机上的端口 8080。这会让cargo认为tomcat没有停止。您可以通过货物配置将 tomcat 的 AJP 端口更改为不常见的端口。请参阅此博客文章了解更多详细信息：

Answer 2

我也有同样的问题。我无法从我的 Hudson 服务器停止容器，而它在我的本地计算机上正确停止，具有相同的 pom.xml 和相同的 Maven 目标和选项。

问题在于 Hudson 位于 Tomcat 上，并且容器和 Tomcat 使用相同的端口。将servlet端口从8080更改为8181，将AJP端口从8009更改为8012（数字任意选择）解决了问题，“停止”目标成功执行。

我必须更改 2 个端口，因为冲突发生在 2 个 Tomcat 之间，如果冲突发生在 Tomcat 和其他东西之间，则可能需要进行 2 个更改之一。

我用来更改端口的两行是：

<configuration>
     ...
     <properties>
        ...
        <cargo.servlet.port>8181</cargo.servlet.port>
        <cargo.tomcat.ajp.port>8012</cargo.tomcat.ajp.port>
        ...
    </properties>
    ...
</configuration>
