Provide an example for compiling to native-image

[eiswind]

I fail with and seemingly endless chain of problems when I try to build a native-image with graalvm.
Has anyone setup a working example?

[jamesward]

There is a lot of reflection happening under the covers so it probably is possible but not easy. Are you looking to do this for server, client, or both?

[eiswind]

My primary target would be the client. I have seen that micronaut and quarkus are doing this for the java server side, but my target is a openjfx client.

[jamesward]

Cool. One more question... Is it ok to use the lite client?

[eiswind]

Heya :) I do not have even a basic idea how this setup would look like :) Maybe you could point me to an example setup with the lite-client? ATM I have a shared module that contains the generated stubs and service skeletons, that I use on both sides.

[jamesward]

Cool. I think lite should work. I'll try to get a sample project going that creates a GraalVM native-image client.

[eiswind]

Ok I get it. Not using netty seems to be a good idea :)

[eiswind]

At least I could compile and connect it now with the lite-stubs. Now I see other troubles with openjfx :(
Thanks a lot for pointing me in the right direction.

@eiswind Are you targeting JVM platform using lite? Would you be willing to share a sample project here since you say you got it working?

[eiswind]

@asarkar Unfortunately I cannot share this code. But it was a no brainer. As soon as I did remove netty and replaced it with the lite libs it did compile without any further effort.

[jamesward]

@asarkar You can find an example lite project build at: https://github.com/jamesward/kotlin-samples/blob/sample-android/run/grpc-sample-android/common/build.gradle.kts

[asarkar]

@jamesward I saw that one already, but I got the impression that @eiswind got lite working for JVM platform, not Android; I also asked specifically and wasn't refuted.

Are you targeting JVM platform using lite?

[jamesward]

Cool. My example does target the JVM. But I'm working on another one that targets Android (AAR). Is that what you are looking for?

[asarkar]

My example does target the JVM

It does? The project name misled me then.

I'll be happy with a JVM example.

[jamesward]

I used lite in the common subproject with the protos and grpc kotlin stuff. It targets the JVM and is used in an android project and a JVM server project.
