Error message: static methods in interface require – target: jvm-1.8
From the perspective of error reporting, it is an error reported by Scala trying to call a static method in the java interface. However, JDK1.8 is used for compiling and packaging in the idea configuration
Modifying the following idea configuration is not valid:
So think about another breakthrough and add the following configuration to the build.gradle file to solve the problem.
project.tasks.compileScala.scalaCompileOptions.additionalParameters = ["-target:jvm-1.8"]
project.tasks.compileTestScala.scalaCompileOptions.additionalParameters = ["-target:jvm-1.8"]
