在IntelliJ中运行时编译

Question

When I run a test in IntelliJ, it doesn't automatically compile the file first. Is this normal behavior? I know I can use eclipse mode to auto compile when I save, but it seems logical to auto compile before running the file. Is this possible in IntelliJ?

Answer 1

There is a "Before Launch" option group under configuration screen, that has "Make" as one of the options. If this option is checked, the whole module/project will be rebuilt prior launching.

If you want this option to persist for all future configurations automatically created by IntelliJ, mark it under relevant configuration in "Defaults" group.

Answer 2

I have made a macro to Save and Compile mapped to CMD+s

Also made a macro to Save, Compile, and Run mapped to CMD+r

EDIT:

According to this link: http://blog.jetbrains.com/scala/2012/12/28/a-new-way-to-compile/

Using the SBT incrementality type rather than IDEA will better detect modifications to the scala files and function as we expect.
