David Li commented on ARROW-15959:
----------------------------------

Tracing my steps: I started with a fresh IntelliJ 2022.1 installation. I installed IdeaVim and CheckStyle-IDEA for reference.

I then opened the {{java}} subdirectory of a fresh Arrow checkout, and waited for the Maven sync. That ran into 

{noformat}
Could not find artifact io.netty:netty-transport-native-unix-common:jar:${os.detected.name}-${os.detected.arch}:4.1.72.Final in central (https://repo.maven.apache.org/maven2)
{noformat}

This seems to be related to https://github.com/trustin/os-maven-plugin/issues/19. I updated the plugin and re-opened the IDE, which seemed to fix it mostly, except in flight-integration-tests which had

{noformat}
Unresolved dependency: 'io.netty:netty-transport-native-unix-common:jar:4.1.72.Final'
{noformat}

Adding the os-maven-plugin didn't help here. Deactivating the linux-netty-native profile in the Maven pane did. I think this might be because IntelliJ isn't substituting the os properties when dependencies come from a profile. 

Now Maven syncs. I tried to build the project and had to set an SDK. I chose JDK11 and set the language level to 8, then tried building again. That led to

package sun.misc does not exist

> 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
