Question

• What do you want to know?

We are using Skywalking java agent with Spring Boot and they work together very well.

Recently, I am looking into Spring Native to speed up Spring Boot in Docker container.

https://docs.spring.io/spring-native/docs/current/reference/htmlsingle/

However, It seems that Spring Native and GraalVM do not support java agent currently.

oracle/graal#1065

I understand this defect is not about Skywalking, but is there a solution to use Skywalking when java agent is not an option?

Is there a feature that I can instrument java class with Skywalking during compile time?

Thanks!

In theory, of course, you could. We keep our eyes on all static compiling solution for a while. But the community don't have anyone saying he/she wants to lead on that part.

Is there any document about Skywalking static compiling that I can start with?

There isn't. No PMC member is on this. I think you could learn how Java compiling plugin works, such as maven system.
BTW, this solution also could work for Android. So, it is valuable, but complex.

• I don't intend to open a new discussion, so I'm hanging some pending things under this discussion to identify you with some PRs that might change.

• Spring Native has entered maintenance, so I'll go straight to org.springframework.boot:spring-boot-maven-plugin:3.0.0-M4 instead of talking about org.springframework.boot:spring-boot-maven-plugin:2.x .

• spring-boot-maven-plugin:3.0.0-M4 is packaged GraalVM Native Image with Paketo BuildPacks, when you configure -javaagent:app/META-INF/skywalking-agent.jar via environment variable JAVA_OPTS, what error log do you see? The configuration in Paketo BuildPacks should be similar to Support (or document how to bundle/use) custom Java Agents cloudfoundry/java-buildpack#555 (comment) .
