在Eclipse中使用Tomcat運行時調試的Bluemix失敗

Question

按照以下步驟，嘗試從Eclipse在Bluemix Tomcat服務器上調試我的Web應用程序時，出現了與Bluemix遠程調試會話未啟動相同的問題。

1. 全新安裝的eclipse-jee-neon-R-win32-x86_64和所有必需的Eclipse插件（例如，用於Bluemix for Neon的Eclipse工具）。
2. 在Bluemix中創建了一個新的Cloud Foundry App，選擇Tomcat作為運行時，然后添加Git並構建和部署了名為“ TomcatHelloWorldApp”的示例Web應用程序。
3. 從Jazz Git存儲庫將“ TomcatHelloWorldApp” Web應用程序克隆到我的Eclipse。
4. 在Eclipse中創建了新的IBM Bluemix服務器，添加並推送“ TomcatHelloWorldApp” Web應用程序。
5. 右鍵檢查IBM Bluemix服務器下的Web應用程序，然后選擇“啟用應用程序調試”。

但是，我得到下面的錯誤。 即使使用Bluemix創建的默認Web應用程序也無法使用：

然后，我嘗試修改代碼並使其在Java 1.8中正常工作。將Maven pom.xml文件修改為

        <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文件中添加以下設置。

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

還要如下修改Build Shell命令

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

它可以成功構建和部署，並且現在可以在Java 1.8上正常運行。

但是，當我嘗試“啟用應用程序調試”時，我又遇到了同樣的問題……請您提供任何幫助嗎？

如果您將IBM JVM用作工作台JVM，那么Bluemix 故障排除文檔將提供更多詳細信息來解決此問題。
