 I shaded apache-dbcp2 into my .jar, but when server reaches any usage of this library's classes - it throws NoClassDefFoundError:

Posting my build.gradle that did the trick(Used ShadowJar due to inability to did it with Forge Gradle) seems like the only way to do it now :
  

buildscript {
    
    repositories {
        jcenter()
        mavenCentral()
        maven {
            name = "forge"
            url = "http://files.minecraftforge.net/maven"
        }
        maven {
            name = "sonatype"
            url = "https://oss.sonatype.org/content/repositories/snapshots/"
        }
    }
    
    dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:2.3-SNAPSHOT'
        classpath 'com.github.jengelman.gradle.plugins:shadow:1.2.3'
    }
}
apply plugin: 'net.minecraftforge.gradle.forge'
apply plugin: 'java' // or 'groovy'. Must be explicitly applied
apply plugin: 'com.github.johnrengelman.shadow'

version = "0.7.1.26"
group = "minedonate"
archivesBaseName = "minedonate"

[compileJava, compileTestJava]*.options*.encoding = 'UTF-8'

sourceCompatibility = targetCompatibility = '1.8'
compileJava {
    sourceCompatibility = targetCompatibility = '1.8'
}

minecraft {
    version = "1.12.2-14.23.0.2491"
    runDir = "run"
    mappings = "snapshot_20170612"
    makeObfSourceJar = false
}

configurations {
    shadow
    compile.extendsFrom shadow
}

dependencies {
    shadow   'org.apache.commons:commons-dbcp2:2.1.1'
    shadow   'org.apache.commons:commons-pool2:2.4.2'
    shadow   'mysql:mysql-connector-java:8.0.11'
}
shadowJar {
    archiveName = tasks.jar.archiveName
    configurations = [project.configurations.shadow]
    relocate 'org.apache.commons', 'ru.alastar.org.shadowedlibs.org.apache.commons'
}

jar {
    configurations.shadow.each { dep ->
        from(project.zipTree(dep)){
            exclude 'META-INF', 'META-INF/**'
        }
    }
}
jar.dependsOn shadowJar
jar.enabled = false

processResources {
    inputs.property "version", project.version
    inputs.property "mcversion", project.minecraft.version

    from(sourceSets.main.resources.srcDirs) {
        include 'mcmod.info'
        expand 'version': project.version, 'mcversion': project.minecraft.version
    }

    from(sourceSets.main.resources.srcDirs) {
        exclude 'mcmod.info'
    }
}
