GraalVM build is failed

I'm trying to build native image of my SpringBoot 3 app with generated configuration from agent of native-image-agent

My steps I currently do:

  • Building of .jar: mvn -DskipTests spring-boot:run with jvmArgs which provided in maven configuration:
<jvmArguments>
    -agentlib:native-image-agent=config-output-dir=target/native-image
</jvmArguments>
  • Next step is I remove jvmArgument which builds configuration and run command which builds native image: mvn -DskipTests -Pnative clean package

In generated reflect-config.json of the first step I can find configuration for HikariConfig class and method setConnectionTimeout(long ms), but when I try to run generated in second step native image I can see this error:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'commonDataSource': Runtime reflection is not supported for public void com.zaxxer.hikari.HikariConfig.setConnectionTimeout(long)

Seems that this configuration is not loaded during native image build. Probably I should set some config path variable or put config to some folder, could you help me please?

Solution

  • The configuration files generated by the Tracing Agent must be put under META-INF/native-image (as described here).

    Your project structure should look like this:

    Project
|__src
   |__main
      |__java
      |__resources
         |__META-INF
            |__native-image <-- Put the configuration files in this folder

    Then start the native image build again: mvn -DskipTests -Pnative clean package

    If you run the binary, the exception should be gone.
