1 year ago Another interesting thing: I could create a native image on a separate virtual machine with GraalVM: native-image -jar vsm.jar but the result is interesting :) I can't run the executable output without the original jar when I try to run without that I got this error:
Error: Could not find or load main class org.springframework.boot.loader.JarLauncher
Caused by: java.lang.ClassNotFoundException: org.springframework.boot.loader.JarLauncherWith the original jar it works perfectly, but I can't put it or (these) into a docker container, all the time I got this error:
exec ./vsm: no such file or directoryBut I know the files are there! The Dockerfile:
FROM alpine:latest
COPY vsm /app/
COPY vsm.jar /app/
WORKDIR /app
RUN chmod +x vsm
RUN chmod +x vsm.jar

Dear All,
I'd like to convert my app to a GraalVM native image, but I get this exception without more detailed information about the problem in my code.
Thank You so much for any help!
