Thanks so much for your help! I removed the log4j dependency, I honesty don't remember when I put that there. Once I fixed the jar.finalizedBy line, everything worked! (One small issue where I was relocating all of "com.google" when I just should've relocated "com.google.common," too) Thanks again!

I have multiple shadowed dependencies in my mod, and it seems that something isn't working correctly here... When I look in the jar file, all of my dependencies are properly relocated and included, but I seem to have an issue with Minecraft recognizing it as a mod. The error says Very strange. The debug.log shows the mod failed to load because of a Here's my build.gradle if that will be any help. buildscript { repositories { maven { url = 'https://files.minecraftforge.net/maven' } maven { url = "https://plugins.gradle.org/m2/" } jcenter() mavenCentral() } dependencies { classpath group: 'net.minecraftforge.gradle', name: 'ForgeGradle', version: '3.+', changing: true } } plugins { id "com.github.johnrengelman.shadow" version "2.0.4" } apply plugin: 'java' apply plugin: 'net.minecraftforge.gradle' apply plugin: 'eclipse' apply plugin: 'maven-publish' version = '1.0' group = 'com.mod.mod' // http://maven.apache.org/guides/mini/guide-naming-conventions.html archivesBaseName = 'mod' sourceCompatibility = targetCompatibility = compileJava.sourceCompatibility = compileJava.targetCompatibility = '1.8' // Need this here so eclipse task generates correctly. //Print out JVM information so that we know what version is running.

Thanks in advance!

But now that I've entered the game, I've noticed a fatal flaw. None of my block or items registered. I think it's because of ignoring the Minecraft dependencies, so I'll need to keep on working.

I changed my shadowJar config to this: shadowJar { relocate('com.google', 'org.(modid).google') configurations = [project.configurations.shadow] classifier '' relocate('org.apache', 'org.(modid).apache') } And I have success!

I used this to get the libraries back: shadow group: 'org.apache.logging.log4j', name: 'log4j-api', version: '2.11.2' shadow group: 'org.apache.logging.log4j', name: 'log4j-core', version: '2.11.2' But now I'm getting this: java.lang.NoSuchMethodError: com.google.common.util.concurrent.SimpleTimeLimiter.create(Ljava/util/concurrent/ExecutorService;)Lcom/google/common/util/concurrent/SimpleTimeLimiter;

Now we're getting somewhere... here's my build.gradle: configurations { provided compile.extendsFrom provided } dependencies { minecraft 'net.minecraftforge:forge:1.15.2-31.2.36' shadow group: 'org.seleniumhq.selenium', name:'selenium-java', version:'3.141.59' } shadowJar { configurations = [project.configurations.shadow] classifier '' relocate('org.apache', 'org.(modid).apache') } processResources { inputs.property "version", project.version inputs.property "mcversion", "1.15.2-31.2.36" from(sourceSets.main.resources.srcDirs) { include 'mcmod.info' expand 'version':project.version, 'mcversion': "1.15.2-31.2.36" } from(sourceSets.main.resources.srcDirs) { exclude 'mcmod.info' } } project.tasks.build.dependsOn shadowJar The file size drastically shrinks, and Minecraft recognizes it as a mod! But now, I'm getting: java.lang.NoClassDefFoundError: org/(modid)/apache/logging/log4j/LogManager So there might be more work to do...

I've relocated the Apache libraries now, but it's still not recognizing. When I recompile the jar, it appears that it has additionally copied all of Minecraft Forge's files. I think Shadow is picking up the: minecraft 'net.minecraftforge:forge:1.15.2-31.2.36' in dependencies{}... I can't get exclude to work on this dependency, and I think this may be the solution.

It runs fine with runClient, but when it's built, it's not recognized at all.

All my libraries are inside the jar now, but Minecraft does not recognize it as a mod anymore...

At this point, I've reimplemented the Shadow plugin, but it makes no changes to the jar unless I use: project.tasks.build.dependsOn shadowJar which makes a much larger jar, and I assume my dependencies are somewhere in there, but Minecraft does not recognize it as a mod. When I used the dependencies{} block in the shadowJar{} block, and included my dependencies, it would generate a 1 KB jar, which is definitely not right at all. Other than including the plugin, here's the code that Shadow effects: dependencies { minecraft 'net.minecraftforge:forge:1.15.2-31.2.36' compile group: 'org.seleniumhq.selenium', name:'selenium-java', version:'3.141.59' } shadowJar { relocate 'org.apache.commons.exec', 'org.(modid).apache.commons.exec' classifier '' } Thanks all for your help.

I'm guessing I still need to move the Apache library somehow, because I always get NoClassDefFoundError when calling it... If you still aren't allowed to use Apache libraries (I read old forum posts saying you can't include those normally), I guess that would explain the error. I couldn't figure out the Shadow plugin, it didn't seem to include any dependencies, so I used that guide, I'll try again with Shadow. Thanks.

I'm trying to use this guide now. Forge doesn't seem to have srgExtra or extraLines anymore, is there an alternative?

Is it just crossed out, or not allowing the game to run? If you're using IntelliJ or Eclipse, you'll see a line through a class or method name if it's deprecated. It shouldn't crash the game because of that.

I changed it to use the plugins{} block instead. shade wasn't a valid option, so I stuck with shadow. But I see some examples just using compile, does that work anyway? Okay, here's my shadowJar{} block I added: shadowJar { relocate 'org.apache', 'org.(modid).apache' } I'm still getting NoClassDefFoundError, though. Thanks for your help so far.

I looked into shadowing, and I added the plugin to my Gradle file. Before, I was "shading" using this: configurations.shade.each { dep -> from(project.zipTree(dep)){ exclude 'META-INF', 'META-INF/**' } } ...but I'm guessing that isn't the same thing. I needed to use version 4.0.4, because 6.0 didn't support the version of Gradle I'm using. When I build the jar, the logs show a NoClassDefFoundError for the main package of the dependency. All I've added to build.gradle is: buildscript { repositories { maven { url = 'https://files.minecraftforge.net/maven' } maven { url = "https://plugins.gradle.org/m2/" } jcenter() mavenCentral() } dependencies { classpath group: 'net.minecraftforge.gradle', name: 'ForgeGradle', version: '3.+', changing: true classpath "com.github.jengelman.gradle.plugins:shadow:4.0.4" } } apply plugin: 'net.minecraftforge.gradle' apply plugin: 'eclipse' apply plugin: 'maven-publish' apply plugin: "com.github.johnrengelman.shadow" dependencies { minecraft 'net.minecraftforge:forge:1.15.2-31.2.36' shadow 'nameofdependency' } Maybe there is more configuration needed?
