Describe the Issue

I'm trying to build a project native and I am getting following error:

Failed generating 'data-server' after 25.1s.

Is there a option to get more information why this error occurs?

Interesting part: The project normally uses logback for logging. I just removed it for native build but first forgot to remove the prometheus LogbackMetrics(). Then it was able to build native, but failed on start due to not having some logback classes.
After removing the LogbackMetrics() I get the build error above.

Using the latest version of GraalVM can resolve many issues.

• I tried with the latest version of GraalVM.

GraalVM Version

Java(TM) SE Runtime Environment Oracle GraalVM 23.0.1+11.1 (build 23.0.1+11-jvmci-b01)
Java HotSpot(TM) 64-Bit Server VM Oracle GraalVM 23.0.1+11.1 (build 23.0.1+11-jvmci-b01, mixed mode, sharing)

Operating System and Version

Mac OS 15.1.1

Build Command

Using gradle with:

graalvmNative {
    toolchainDetection = true
    binaries {
        main {
            mainClass = "com.x.DataServerMain"
            buildArgs.add("-H:+AllowDeprecatedBuilderClassesOnImageClasspath")
            buildArgs.add("-Ob")
            verbose = true
            javaLauncher = javaToolchains.launcherFor {
                languageVersion = JavaLanguageVersion.of(23)
                vendor = JvmVendorSpec.matching("Oracle Corporation")
            }
        }
    }
}

Expected Behavior

The build went through or there are more instructions on the error

Actual Behavior

Fails with the error jdk.graal.compiler.debug.GraalError: should not reach here: unexpected encoding: true true

Steps to Reproduce

I don't know yet how to reproduce it on a small sharable project

Hello @joggeli34,
You can get more output information at build time with this arg:
buildArgs.add("--verbose")

Please confirm if you are creating the config files (ref here).
If you haven't, please check the documentation about it for gradle here.

Finally, not having a reproducer will make it very hard for us to understand the problem and get a solution for it.
