Question

我遇到与Bluemix remote debugging session not starting相同的问题尝试从Eclipse在Bluemix Tomcat服务器上调试我的Web应用程序时，请按照以下步骤操作。

全新安装的eclipse-jee-neon-R-win32-x86_64等等必需的Eclipse插件（例如，用于Neon的Bluemix的Eclipse工具）。
在Bluemix中创建了一个新的Cloud Foundry应用程序 Tomcat作为运行时，然后添加Git并构建和部署示例Web 应用程序称为'TomcatHelloWorldApp'。
克隆了来自Jazz Git的'TomcatHelloWorldApp'网络应用程序到我的Eclipse 库中。
在Eclipse中创建新的IBM Bluemix服务器，添加并推送'TomcatHelloWorldApp'网络应用程序。
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，我收到以下错误。即使使用Bluemix创建的默认Web应用程序，它也不起作用：

然后我尝试修改代码并使其与Java 1.8一起正常工作将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]}

同时修改Build Shell Command，如下所示

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

它成功构建和部署，现在可以正常使用Java 1.8。

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...... 你能对此提供任何帮助吗？

如果您使用IBM JVM作为工作台JVM，则Bluemix troubleshoot doc有更多详细信息可以解决此问题。

Eclipse中使用Tomcat运行时调试的Bluemix失败
