[GR-64746] [Native Image] Dependencies from GraalVM collide with svm-wasm-guava.jar when building to wasm

[treblereel]

Describe the Issue

SDK: 25.ea.20-graal
OS X: macOS

In my Maven project I have a dependency on org.kie:kie-ci:jar:10.0.0:compile, which in turn transitively depends on com.google.guava:guava:jar:32.0.1-jre:compile.

During the build I see many warnings like:

Warning: Class-path entry file:///Users/treblereel/.m2/repository/com/google/guava/guava/32.0.1-jre/guava-32.0.1-jre.jar contains class com.google.common.base.Joiner. This class is part of the image builder itself (in file:///Users/treblereel/.sdkman/candidates/java/25.ea.20-graal/lib/svm/tools/svm-wasm/builder/svm-wasm-guava.jar) and must not be passed via -cp.
Warning: Class-path entry file:///Users/treblereel/.m2/repository/com/google/guava/guava/32.0.1-jre/guava-32.0.1-jre.jar contains class com.google.common.base.Joiner$MapJoiner. This class is part of the image builder itself (in file:///Users/treblereel/.sdkman/candidates/java/25.ea.20-graal/lib/svm/tools/svm-wasm/builder/svm-wasm-guava.jar) and must not be passed via -cp

However, at runtime I get:

Exception in thread "main" java.lang.NoClassDefFoundError: com.google.common.collect.ImmutableSet

Could it be that the Guava from my transitive dependency and the Guava bundled in svm-wasm-guava.jar are incompatible?

I tried excluding Guava in my native-maven-plugin configuration:

<plugin>
  <groupId>org.graalvm.buildtools</groupId>
  <artifactId>native-maven-plugin</artifactId>
  <configuration>
    <mainClass>org.treblereel.graalvm.wasm.App</mainClass>
    <imageName>../web/app</imageName>
    <exclusions>
      <exclusion>
        <groupId>org.google.guava</groupId>
        <artifactId>guava</artifactId>
      </exclusion>
    </exclusions>
  </configuration>
</plugin>

—but it didn’t help.

Thank you for your assistance.

Using the latest version of GraalVM can resolve many issues.

Steps to Reproduce

1. create maven project
2. add dependency with transitive guava dependency
3. setup a wasm build of native image
4. compile and run

@fniephaus may I ask you to take a look please?
Thank you

[fniephaus]

Sure, @treblereel. It seems we've added Guava as a dependency recently (see here), but forgot to shade it.

@patrick96 Could you please make sure that all dependencies of the web-image suite are properly shaded? Thanks!

[treblereel]

Thank you @fniephaus for such a quick response!

I still haven’t been able to get JS.Export to work (I tried the example from JSObject), but that’s beyond the scope of this issue.

[fniephaus]

Please file another ticket for JS.Export. Not sure what you try to do, so please elaborate and provide a code snippet. Maybe @patrick96 can help you with this, too.

[patrick96]

We're tracking this internally as GR-64746

[treblereel]

@patrick96 thank you for work you do, do you have any time estimates regarding this bug? Thanks.

The goal is to get the fix for this merged before June
