[SOLVED] How can I import an external librarie?

[Tatuck]

Hello. I am trying to use a gradle librarie in my mod. But when I use "gradlew build" it doesn't compile my librarie and in-game it shows me an error (classnotfoundexception).

How can I do that? Thanks

I have tried but for some reason Minecraft doesn't detect the compiled mod. I don't think it is giving me an error because I have checked the logs but I found nothing.

My build.gradle: 

buildscript {

        maven { url = 'https://files.minecraftforge.net/maven' }
        mavenCentral()

apply plugin: 'net.minecraftforge.gradle'

java.toolchain.languageVersion = JavaLanguageVersion.of(8) // Mojang ships Java 8 to end users, so your mod should target Java 8.

Update: 

I have tried again and now it is showing me this error:

I didn't know I had to reobfuscate the mod, I created it using: "gradlew shadowJar"

[Tatuck]

Finally!!! Thank you! It worked perfectly! I run "gradlew reobfShadowJar" and it worked perfectly! Thanks for your help!
