如何在使用GAE Maven插件时在IDEA中调试Java Google App Engine应用程序？ [英] How can I debug a Java Google App Engine app in IDEA while using the GAE Maven plugin?

问题描述

我已经像 那样设置了我的pom.xml，并且它似乎是工作的大部分，我可以启动devserver和更新应用程序。

我的问题是，我似乎无法调试devserver。我试图在IDEA中以调试模式启动devserver maven目标，但是当我设置断点时，它们被忽略。

我在GAE Maven插件文档中发现可以启动在调试模式下使用以下配置的devserver：

 < jvmFlags> 
< jvmFlag> -Xdebug< / jvmFlag> 
< jvmFlag> -agentlib：jdwp = transport = dt_socket，address = 8000，server = y，suspend = n  
< / jvmFlags> 
  

然而，我不知道如何告诉IDEA连接调试器，当我启动Maven Run /调试配置。

任何人都可以指出我正确的方向吗？

解决方案

在你的问题中提到的配置看起来不错。所以，你有：

< jvmFlags>
< jvmFlag> -Xdebug< / jvmFlag>
< jvmFlag> -agentlib：jdwp = transport = dt_socket，address = 8000，server = y，suspend = n
< / jvmFlags>


1. 当您运行Maven构建版本

     mvn appengine：devserver 
     

   
   
   <在某些时候它暂停并等待远程调试器连接。在IDEA中，转到运行>

编辑配置... 并添加新的远程配置。


2. 给它一个名称和检查参数


3. 点击确定

4. 用 Run>运行调试器。调试'<您的配置名称>'（ Shift-F9 ）

I have set up my pom.xml like so, and it appears to be working for the most part, I can start the devserver and update the application.

My problem is that I can't seem to debug the devserver. I tried launching the devserver maven goal in debug mode from within IDEA, but when I set breakpoints they are ignored.

I found in the GAE Maven plugin docs that you can launch the devserver in debug mode with the following configuration:

<jvmFlags>
  <jvmFlag>-Xdebug</jvmFlag>
  <jvmFlag>-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n</jvmFlag>
</jvmFlags>

However I don't know how to tell IDEA to connect the debugger when I start the Maven Run/Debug configuration.

Can anyone point me in the right direction?

解决方案

The configuration mentioned in your question looks good. So, you have:

<jvmFlags>
  <jvmFlag>-Xdebug</jvmFlag>
  <jvmFlag>-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n</jvmFlag>
</jvmFlags>

1. When you run your Maven build

   mvn appengine:devserver
   

   at some point it halts and waits for the remote debugger to connect.

2. In IDEA, go to Run > Edit Configurations... and add a new Remote configuration.

3. Give it a name and check parameters (especially the port).
4. Click OK
5. Run the debugger with Run > Debug '<name of your config>' (Shift-F9)
