Java 谷歌云调试器可以'；找不到作为云运行服务部署的Spring Boot web应用

我按照指南（）为我的云运行服务设置了云调试器。一切看起来都应该正常。但是调试器UI告诉我它找不到任何应用程序

然而，我做了文档中提到的所有事情

• 源代码位于源代码存储库中
• 云构建在

  master

  push上触发
• 我下载了

  cdbg java代理。所以

• 我使用

  -agentpath

  选项运行java应用程序
• 正在通过

  cloudbuild.yaml部署云运行服务

• 云运行服务启动正常，运行正常

但是，正如您在屏幕截图中看到的，在成功部署后，无法找到我的应用程序

以下是我的配置的一些详细信息：

• 弹簧靴v2.4.2
• Kotlin 1.4.21

这是我的文件

CMD ["java", "-agentpath:/app/agent.so", "-Dcom.google.cdbg.breakpoints.enable_canary=false", "-jar", "app.jar"]

这是docker构建输出

如果查看压缩的代理文件中的内容，您会注意到其中有几个文件名为：

cdbg_java_agent.so

cdbg_java_agent_internals.jar

version.txt

出现此问题是因为您没有将internals.jar文件复制到/app dir。共享对象文件具有依赖关系，这可以解释为什么指示用户为调试器创建单独的目录

要解决此问题，请将缺少的文件添加到Dockerfile中，如下所示：

COPY --from=agent /agent/cdbg_java_agent.so agent.so
COPY --from=agent /agent/cdbg_java_agent_internals.jar cdbg_java_agent_internals.jar
COPY --from=build /dist/build/libs/user-service.jar app.jar

---

然后等待约5分钟，直到您的服务出现在调试器上。请注意，源代码不会出现，除非它位于Git repo上。为此，您必须这样做。
