在Eclipse中使用Tomcat运行时调试的Bluemix失败

Question

按照以下步骤，尝试从Eclipse在Bluemix Tomcat服务器上调试我的Web应用程序时，出现了与Bluemix远程调试会话未启动相同的问题。

1. 全新安装的eclipse-jee-neon-R-win32-x86_64和所有必需的Eclipse插件（例如，用于Bluemix for Neon的Eclipse工具）。
2. 在Bluemix中创建了一个新的Cloud Foundry App，选择Tomcat作为运行时，然后添加Git并构建和部署了名为“ TomcatHelloWorldApp”的示例Web应用程序。
3. 从Jazz Git存储库将“ TomcatHelloWorldApp” Web应用程序克隆到我的Eclipse。
4. 在Eclipse中创建了新的IBM Bluemix服务器，添加并推送“ TomcatHelloWorldApp” Web应用程序。
5. 右键检查IBM Bluemix服务器下的Web应用程序，然后选择“启用应用程序调试”。

但是，我得到下面的错误。 即使使用Bluemix创建的默认Web应用程序也无法使用：

然后，我尝试修改代码并使其在Java 1.8中正常工作。将Maven pom.xml文件修改为

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.5.1</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin> 

在manifest.yml文件中添加以下设置。

  env:
    JBP_CONFIG_IBMJDK: '[version: 1.8.+]'
    JBP_CONFIG_LIBERTY: 'app_archive: {features: [websocket-1.1, servlet-3.1]}

还要如下修改Build Shell命令

#!/bin/bash
export JAVA_HOME=/opt/IBM/java8
mvn -B package

它可以成功构建和部署，并且现在可以在Java 1.8上正常运行。

但是，当我尝试“启用应用程序调试”时，我又遇到了同样的问题……请您提供任何帮助吗？

如果您将IBM JVM用作工作台JVM，那么Bluemix 故障排除文档将提供更多详细信息来解决此问题。
