Description

A few more things need to be documented to get debugging working in IntelliJ, at least in my experience. This is probably because instead of using the Maven build, I'm using IntelliJ's native build, which lets me one-click run a particular class or test, but needs some extra configuration.

• Must unset "Use --release option for cross compilation" in compiler settings
• Must build once with Maven and mark the arrow-vector/target/generated-sources directory as a generated sources root
