I have issue with minecraft mod

[VVriter]

When im trying to include it to jar and run minecraft - it crushes with folowing error:

java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
at com.github.sarxos.webcam.Webcam.(Webcam.java:101)

but if i open /jar file with archivator, this class exist. This is cuz when minecraft injectings mods - he exclude all org. packages.

Im using folowing gradle code:

buildscript {
repositories {
mavenCentral()
maven { url = "https://plugins.gradle.org/m2" }
maven { url = "https://repo.spongepowered.org/maven" }
maven { url = "https://maven.minecraftforge.net/" }
}
dependencies {
classpath group: 'net.minecraftforge.gradle', name: 'ForgeGradle', version: '3+', changing: true
classpath 'com.github.jengelman.gradle.plugins:shadow:4.0.3'
}
}
apply plugin: 'net.minecraftforge.gradle'
apply plugin: 'com.github.johnrengelman.shadow'

version = "1.12.2"
group = "ru.packetdupe.mod"
archivesBaseName = "ratnichek"

sourceCompatibility = targetCompatibility = 1.8
compileJava.options.encoding = compileTestJava.options.encoding = "UTF-8"

minecraft {

mappings channel: 'stable', version: "39-1.12"
runs {
    client {
        workingDirectory project.file('run')

        property 'forge.logging.markers', 'REGISTRIES'

        property 'forge.logging.console.level', 'debug'
    }
}
