[native-image] Failed to compile spring-boot project to native image (UnsupportedFeatureException) #348
Comments
Thank you for your report. Spring-boot uses dynamic class loading which is a limitation of SubstrateVM. Sometimes it is possible to avoid dynamic class loading (which might reduce some functionality). I will look into this possibility for spring-boot. |
You can get past this specific error by not using the fat jar launcher as a main method. But there are other bogies lurking. Spring Boot has a static (but optional) dependency on Groovy, for example, so even though it will never be used at runtime, a native-image cannot be built because |

I have created SPR-16991 to track SubstrateVM Spring support status. |
More than a week ago Josh Long at the beginning of his Devoxx (devoxx.pl) talk demoed a Spring Boot/Fu app built as a native image using GraalVM: spring-projects-experimental/spring-fu#29 |

Neither of those apps uses Spring Boot. |
The originally reported issue has been fixed. With the latest release, you can build an image using
It looks like the example app tries to execute a jar which is currently not supported with |
