GraalVM native-image fails with minimum configuration
shainegordon opened this issue · comments
I'm very new to GraalVM, so I am hoping this is a simple fix, with some better understanding.
I was having issues with GraalVM and Groovy dependencies while using version nz.net.ultraq.thymeleaf.thymeleaf-layout-dialect@3.2.0, on step 7 - compiling
I then found this issue - #232 - which alerted me to the existence of 3.2.1
However, this doesnt actually allow this lib to be used in a project that wants to use GraalVM.
Quite easy to reproduce, and I have pushed to a demo repository - https://github.com/shainegordon/thymleaf_layout_graalvm
This can be reproduced by running either
docker build -t thymleaf_layout_graalvm .
OR
./mvnw clean native:compile -Pnative
This is a minimal project, created at https://start.spring.io/, with only "Web" and "Native" added. Kotlin, Maven, Java 17, Spring boot 3.0.5.

It is also possible that this library cannot actually work with Spring Boot & GraalVM, as Groovy does not seem to be supported as per https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-with-GraalVM#general
+1 I'm facing the exact same issue
Thanks for raising this and for putting together a demo project for me to test with - I'm also new to GraalVM and mostly learned what I know while debugging that last issue that you linked to! 😅 (I was surprised that I could even get something to go given that Groovy is very much in the 'not supported' list of GraalVM.)
I'll give this a look when I get some time and hopefully your demo project reveals something new that I've missed 🤞
Had a look at this over the last few weekends and managed to get something going, and once I pared it all back to see what actually made a difference the solution came back to that java.beans.Introspector was unintentionally initialized at build time. error that was in the initial post.
I had this error while working on the linked issue as well, and was able to get around it by telling GraalVM to initialize those classes at build time anyway: https://github.com/ultraq/thymeleaf-layout-dialect/blob/1af5824e33f61923a7f5700f2c41ede885f35b62/thymeleaf-layout-dialect-benchmark/source/META-INF/native-image/nz.net.ultraq.thymeleaf/thymeleaf-layout-dialect-benchmark/native-image.properties
So translating those to your setup, I made the following modifications to your pom.xml file:
Configure the native-maven-plugin:
<plugin>
<groupId>org.graalvm.buildtools</groupId>
<artifactId>native-maven-plugin</artifactId>
<configuration>
<buildArgs>
<arg>--initialize-at-build-time=com.sun.beans</arg>
<arg>--initialize-at-build-time=java.beans.Introspector</arg>
</buildArgs>
</configuration>
</plugin>And I also had to add <arg>-jvm-target=17</arg> to the <configuration>/<args> section of the kotlin-maven-plugin to get it to compile on my machine, but it looks like your setup didn't need it? 🤷♂️
I'm now wondering if I should include those args in the layout dialect bundle that gets uploaded (I do include a bunch of other stuff which I'm still on the fence about: https://github.com/ultraq/thymeleaf-layout-dialect/blob/1af5824e33f61923a7f5700f2c41ede885f35b62/thymeleaf-layout-dialect/source/META-INF/native-image/nz.net.ultraq.thymeleaf/thymeleaf-layout-dialect/native-image.properties The line with where the responsibility for all this lies is getting very fuzzy and feels like something that should be fixed once GraalVM provides proper Groovy support 🤔
Somehow I missed your update @ultraq
I’ll definitely revisit this on my side too
