when I ran "sbt run", I could successfully pass the compilation but then failed on run the code. Here is the error: java.lang.RuntimeException: No main class detected. The weird thing is when I do not use SBT, I can run it without any issue: >scalac actor.scala >scala pingpo...
否则,通过sbt run运行之后,会提示以下错误: [error] java.lang.RuntimeException: No main class detected. [error] at scala.sys.package$.error(package.scala:30) [error] stack trace is suppressed; run last Compile / bgRun for the full output [error] (Compile / bgRun) No main class detected....
崩溃~大脑休克~。冷静... No main class detected。说明没有main啊。原来SBT有自己默认的项目文件结构,要在src/main/scala/下创建scala源代码才可以。 注意到src/main/scala/Hello.Scala中,断点的图示有了变化。 这下可以了。下面,就可以调式了。这里简单f9,让它跑完。 那么,有没有办法改变这个默认的项目结构...

Another element is that when I try to run the scala compiler using this icon, it simply can't run and looking at the IntelliJ logs, no error is displayed. Pretty much nothing happens actually. Please find attached the idea.log below. ...
Seed works around these bugs by setting up the dependencies correctly (from <module>-jvm to <module> and vice-versa). Although IDEA will show an error in the settings because it detected a circular dependency, but code highlighting and compilation will still work fine....
