我正在做一个mod jar。我需要在最终的jar（org.apache.httpcomponents：httpasyncclient：4.1.5）中包含一个外部库。我正在使用Shadow插件来制作脂肪罐。但是，我无法正确地包含依赖项。
下面是我的build.gradle：

buildscript {
    repositories {
        jcenter()
        maven {
            name = "forge"
            url = "https://files.minecraftforge.net/maven"
        }
    }
    dependencies {
        classpath "net.minecraftforge.gradle:ForgeGradle:2.1-SNAPSHOT"
    }
}
plugins {
    id "com.github.johnrengelman.shadow" version "4.0.4"
    id "java"
}
apply plugin: "net.minecraftforge.gradle.forge"

configurations {
    shade
    implementation.extendsFrom shade
}
repositories {
    jcenter()
}
dependencies {
    compile "org.apache.httpcomponents:httpasyncclient:4.1.5"
    shade "org.apache.httpcomponents:httpasyncclient:4.1.5"
}
shadowJar {
    classifier = ''
    configurations = [project.configurations.shade]
    finalizedBy 'reobfShadowJar'
}
reobf {
    shadowJar {}
}
tasks.build.dependsOn reobfShadowJar
shadowJar.finalizedBy('reobfShadowJar')
compileJava {
    sourceCompatibility = targetCompatibility = "1.8"
}
archivesBaseName = "${mod_id}"
version = "${mod_version}"
group = "com.<modid>.<modid>"
minecraft {
    version = "1.8.9-11.15.1.2318-1.8.9"
    runDir = "run"
    replace "@VERSION@", project.version
    replaceIn "<Modid>.java"
    mappings = "stable_22"
}
processResources {
    inputs.property "mod_version", project.version
    inputs.property "mc_version", project.minecraft.version
    from(sourceSets.main.resources.srcDirs) {
        include "mcmod.info"
        expand "mod_id":"${mod_id}",
                "mod_name":"${mod_name}",
                "mod_version":"${mod_version}",
                "mod_description":"${mod_description}",
                "mc_version":"${mc_version}"
    }
    from(sourceSets.main.resources.srcDirs) {
        exclude "mcmod.info"
    }
}

当我在IDEA中运行“Minecraft客户端”运行配置时，一切都按预期工作。但是，当我运行gradlew build时，在运行时，我得到Error: net.minecraftforge.fml.common.LoaderException: java.lang.NoClassDefFoundError: /org/apache/http/concurrent/FutureCallback。为什么mod加载器找不到类，即使它们在jar中？（我可能做错了）。
