是否可以在Windows上调试2.3 RC1与激活器jvm调试和Java 8？

Question

我试图使用调试播放框架2.3命令进行activator -jvm-debug 9999 run，但面临以下错误：

E:\workspace\CustomerClub>activator -jvm-debug 9999 run
[info] Loading project definition from E:\workspace\CustomerClub\project

我正在使用Java8更新5

Answer 1

我在Mac电脑上也有同样的问题。一旦我将激活器从1.2.3升级到1.2.12，它就开始工作了。

Answer 2

这可能是Windows上的Activator错误(请参阅我的评论)。同时，您可以通过设置JAVA_OPTS来手动向VM提供调试选项。

例如，试试这个：

> set JAVA_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9999"
> activator
