Issue #50

Really appreciate this work.
Tested your branch. It works as expected without any problems.
Built it with just:

sbt publishLocal

Tested with the following project configuration:

sbt.version = 1.8.2
nativeImageVersion := "22.3.1"
nativeImageJvm := "graalvm-java17"

The only thing I had to my buid.sbt is to specify test mainclass:

Test / mainClass := Some("my.app.ZioSpec")

Is there anything I can help to get this merged and released?

@ckipp @tgodzik @olafurpg Any hope the PR will be merged? ✌️ It's very useful feature, currently I use self-written task for running native tests at my work.

[olafurpg]

This looks like super useful functionality and the PR has detailed tests. LGTM thank you!

[olafurpg]

I'm on the phone right now so can't cut a release. Added a reminder to follow up and merge and release.

Published https://github.com/scalameta/sbt-native-image/releases/tag/v0.3.3 but may take a while for the jars to become available on Maven Central.

@nartamonov could you send a PR adding documentation to the readme so that people can discover this new functionality?

@olafurpg 3 weeks have been passed but still no jars in Maven Central

It looks like the publish job failed https://github.com/scalameta/sbt-native-image/actions/runs/4712517890. Looking I'm not really sure what's going on, but I'll update the release related things in #69 and give it another try.

[ckipp01]

Alright, the 0.3.4 tag correctly released https://github.com/scalameta/sbt-native-image/actions/runs/4893876177/jobs/8737347750. This should be available soon.

@ckipp01 , thank you for resolving it so fast!

I created a small example of how to use new features to automate native image building for Akka HTTP, might be useful for someone:

Hi everyone,

Does anyone know what I have to put in Test / main := Some(???) to run ZIO tests with the new nativeImageTestRun cmd?

I see in @nayavu's example, that for ScalaTest, it's: Test / mainClass := Some("org.scalatest.tools.Runner") but I don't find the equivalent for ZIO.

I tried several things and gets this error:

Error: Method 'zio.test.sbt.ZTestRunnerJVM.main' is declared as the main entry point but it can not be found. Make sure that class 'zio.test.sbt.ZTestRunnerJVM' is on the classpath and that method 'main(String[])' exists in that class.

Thanks
