eclipse中的maven jetty调试问题 [英] maven jetty debugging issue in eclipse

问题描述

我试图调试eclipse中的Maven码头项目。我正在盯着码头，使用mvn clean jetty：run。这是我使用的完整的蝙蝠文件（我在Windows上）。

 设置MAVEN_OPTS = -  Xdebug -Xnoagent  - Djava.compiler = NONE -Xrunjdwp：transport = dt_socket，address = 4000，server = y，suspend = n
 mvn clean jetty：run 
  

我正在pom文件中使用jetty-maven-plugin。

蝙蝠文件可以正常运行，并且没有错误。在eclipse内部，我创建了一个新的调试配置，选择了远程Java应用程序，我使用了4000端口和本地主机。

当我尝试运行调试配置，我总是得到这个错误：

 无法连接到远程VM连接拒绝
拒绝连接：连接
  

有谁知道我如何解决这个问题？我检查了此答案，但没有帮助。

解决方案

解决方案是在MAVEN_OPTS中将其更改为 suspend = y 而不是n 。然后，您执行 mvn jetty：run 命令，它会在Listing for transport dt_socket at address：4000行中暂停。之后，您运行eclipse调试器，它将附加到该进程。

如果使用suspend = n，它将无法正常工作（至少对我来说't）。

I am trying to debug a Maven jetty project in eclipse. I am staring jetty using "mvn clean jetty:run". Here's the complete bat file I'm using (I'm on windows).

set MAVEN_OPTS="-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=n"  
mvn clean jetty:run

I am using the jetty-maven-plugin inside the pom file.

The bat file works ok and starts jetty without errors. Inside eclipse, I created a new debug configuration, chose "Remote Java Application" and I used 4000 for the port and localhost for the host.

When I try to run this debug configuration, I always get this error:

"Failed to connect to remote VM. Connection refused.
Connection refused: connect"

Does anyone know how I can solve this? I checked this answer, but it did not help.

解决方案

The solution was that you have to change it to suspend=y instead of n in the MAVEN_OPTS. Then you do the mvn jetty:run command, and it will pause at the "Listening for transport dt_socket at address: 4000" line. After that, you run the eclipse debugger and it will attach to the process.

If you use suspend=n, it won't work (at least for me it didn't).
