Did this work with rc5? From the error message it looks like you need to register ftl.cli.FirebaseCommand.<init>() for reflection access.

[bootstraponline]

Interesting. I'll try to define a reflectconfig. RC5 didn't work either.

[bootstraponline]

Image building is failing after I defined a reflection config JSON.

I opened a pull request so you can easily reproduce the problem:

• WIP | Add failed graal example Flank/flank#289

@cstancu @christianwimmer this looks like the same thing I commented on in #656.

[cstancu]

@bootstraponline the java.lang.NoClassDefFoundError that your reported after adding the correct reflection configuration was fixed in RC12. You will need to add this options to native-image: --report-unsupported-elements-at-runtime --allow-incomplete-classpath. Also you need to fix the graal_reflectionconfig.json by removing the ftl.cli.firebase.test.android.AndroidRefreshCommand and ftl.cli.firebase.test.ios.IosRefreshCommand entries as those classes don't exist anymore. I guess firebase removed them since you filed this issue.

However, I still cannot successfully build an image for your app. I hit the same problem reported in #783: Non-instantiated type referenced by a compiled method: kotlin.Result$Companion.

I am closing this issue. Please follow the progress of #783.

[bootstraponline]

Thank you for looking into this! I'm excited about using graalvm in the future.

[cstancu]

#783 has been fixed. Now using this command:

native-image --report-unsupported-elements-at-runtime --allow-incomplete-classpath  -jar ./build/libs/flank-SNAPSHOT.jar -H:ReflectionConfigurationFiles=graal_reflectconfig.json -H:IncludeResources="kotlin/*.*" --enable-url-protocols=http

and this reflection configuration file:

I can build an executable which when run does something:

$ ./flank-SNAPSHOT firebase test android run
The project is not set. Define GOOGLE_CLOUD_PROJECT, set project in flank.yml
or save service account credential to /home/cdrtz/.config/gcloud/application_default_credentials.json
 See https://github.com/GoogleCloudPlatform/google-cloud-java#specifying-a-project-id

I am not familiar with the internals of your project so I stopped there. I just wanted to see how far I can get it.

Thanks. I made a simple reproducible example that doesn't require authentication with a service account.

It's awesome to see GraalVM making progress. 🙂
