[1.15.2 - Recommended] Dependency not loading when using 'embed'

[jskidd3]

Hello,

 

I've carefully followed the ForgeGradle dependency documentation as I need to embed a few dependencies in my project.

 

Most of these dependencies are loading and can be used as expected, but one is throwing java.lang.NoClassDefFoundError when I try to make use of the library.

 

I can see that the library has been embedded in the jar file, but the mod crashes when I try to access the library.

 

I'd really appreciate any help working around this.

 

Here is my build.gradle:

// Only edit below this line, the above code adds and enables the necessary things for Forge to be setup.
apply plugin: 'eclipse'

Here is the fairly typical crash log:

Additional clarification

[jskidd3]

@diesieben07 I know it's cheeky of me to tag you directly, but I know you're experienced in dependency management. Would you mind taking a look at this when you get a moment?

[jskidd3]

This post (and your reply specifically) seems very relevant as fmDNS uses org.apache libs.

 

The hack isn't working with 1.15.2 but I'm keen to figure out a way of doing this using transformation anyway.

 

 

 

Edited April 26, 2020 by jskidd3

[jskidd3]

Scratch that. The library com.corundumstudio.socketio includes org.apache references in pom.xml and works without any issues. Just cannot figure this one out.

 

Edit: Getting closer I think. Looks like files prefixed with javax are skipped.

Still struggling. Any help would be hugely appreciated. https://stackoverflow.com/questions/61447264/include-compile-dependencies-when-building-with-shadowjar
