如何使用SBT / Eclipse调试Play框架

Question

阅读该文档，看起来很容易做到。 我只需要用

sbt -jvm-debug 9999 run

但是，我确实有此错误消息：

[info] Loading settings for project play-java-ebean-example-build from plugins.sbt ...
[info] Loading project definition from D:\play\play-java-ebean-example\project
[info] Loading settings for project root from build.sbt ...

作为解决方法，我添加了以下行

-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=9999

在文件中

sbtconfig.txt

只需使用以下命令启动应用程序

sbt run

您将看到跟踪：

Listening for transport dt_socket at address: 9999
