I use assembly plugin in sbt to assemble my project. But errors happen when run by "java -jar xx.jar" -
"no main manifest attribute".
I think it's because there are two files in my src/main/scala/
directory and each with an object extending Application
which means there are two main entry in the project. But I need two applications, one is the server and the other is the test client.
How to handle this two-main-entry
problem in scala sbt. Thanks in advance.
In your SBT build file, define the main class.
If you are using build.sbt, then that would be:
mainClass in assembly := Some("com.domain.Main")
If you are using Build.scala then you could do something like:
lazy val app = (project in file("app")).
settings(assemblySettings: _*)
settings(mainClass in assembly := Some("com.domain.Main"))
