Posted April 26, 20205 yr 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: Spoiler buildscript { repositories { maven { url = 'https://files.minecraftforge.net/maven' } jcenter() mavenCentral() } dependencies { classpath group: 'net.minecraftforge.gradle', name: 'ForgeGradle', version: '3.+', changing: true } } apply plugin: 'net.minecraftforge.gradle' // Only edit below this line, the above code adds and enables the necessary things for Forge to be setup. apply plugin: 'eclipse' apply plugin: 'maven-publish' version = '1.0.0' group = 'io.jupiter.link' // http://maven.apache.org/guides/mini/guide-naming-conventions.html archivesBaseName = 'link' sourceCompatibility = targetCompatibility = compileJava.sourceCompatibility = compileJava.targetCompatibility = '1.8' // Need this here so eclipse task generates correctly. minecraft { mappings channel: 'snapshot', version: '20190719-1.14.3' // makeObfSourceJar = false // an Srg named sources jar is made by default. uncomment this to disable. // accessTransformer = file('src/main/resources/META-INF/accesstransformer.cfg') // Default run configurations. // These can be tweaked, removed, or duplicated as needed. runs { client { workingDirectory project.file('run') // Recommended logging data for a userdev environment property 'forge.logging.markers', 'SCAN,REGISTRIES,REGISTRYDUMP' // Recommended logging level for the console property 'forge.logging.console.level', 'debug' mods { examplemod { source sourceSets.main } } } server { workingDirectory project.file('run') // Recommended logging data for a userdev environment property 'forge.logging.markers', 'SCAN,REGISTRIES,REGISTRYDUMP' // Recommended logging level for the console property

file('src/generated/resources/') mods { examplemod { source sourceSets.main } } } } } repositories { mavenCentral() } configurations { embed compile.extendsFrom(embed) } dependencies { minecraft

} def reobfFile = file("$buildDir/reobfJar/output.jar") def reobfArtifact = artifacts.add('default', reobfFile) { type 'jar' builtBy 'reobfJar' } publishing { publications { mavenJava(MavenPublication) { artifact reobfArtifact } } repositories { maven { url "file:///${project.projectDir}/mcmodsrepo" } } } Here is the fairly typical crash log: Spoiler [26Apr2020

April 26, 20205 yr Author @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?
April 26, 20205 yr Author 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, 20205 yr by jskidd3
April 26, 20205 yr Author 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. Edited April 26, 20205 yr by jskidd3
April 26, 20205 yr Author Still struggling. Any help would be hugely appreciated. https://stackoverflow.com/questions/61447264/include-compile-dependencies-when-building-with-shadowjar
