Not including dependencies in jar

[Miloszp22]

So I tried importing java spark to fabric mod and when I build mod and lunch server it gives me an error saying that spark doesn't exist can someone help? My build.gardle:

plugins {
    id 'fabric-loom' version '0.11-SNAPSHOT'
    id 'maven-publish'
}

sourceCompatibility = JavaVersion.VERSION_17
targetCompatibility = JavaVersion.VERSION_17

archivesBaseName = project.archives_base_name
version = project.mod_version
group = project.maven_group

repositories {
    // Add repositories to retrieve artifacts from in here.
    // You should only use this when depending on other mods because
    // Loom adds the essential maven repositories to download Minecraft and libraries from automatically.
    // See https://docs.gradle.org/current/userguide/declaring_repositories.html
    // for more information about repositories.
}

dependencies {
    // To change the versions see the gradle.properties file
    minecraft "com.mojang:minecraft:${project.minecraft_version}"
    mappings "net.fabricmc:yarn:${project.yarn_mappings}:v2"
    modImplementation "net.fabricmc:fabric-loader:${project.loader_version}"
    // Fabric API. This is technically optional, but you probably want it anyway.
    modImplementation "net.fabricmc.fabric-api:fabric-api:${project.fabric_version}"
    implementation group: 'com.sparkjava', name: 'spark-core', version: '2.9.3'
    // PSA: Some older mods, compiled on Loom 0.2.1, might have outdated Maven POMs.
    // You may need to force-disable transitiveness on them.

}

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

    filesMatching("fabric.mod.json") {
        expand "version": project.version
    }
}

tasks.withType(JavaCompile).configureEach {
    // Minecraft 1.18 (1.18-pre2) upwards uses Java 17.
    it.options.release = 17
}

java {
    // Loom will automatically attach sourcesJar to a RemapSourcesJar task and to the "build" task
    // if it is present.
    // If you remove this line, sources will not be generated.
    withSourcesJar()
}

jar {
    from("LICENSE") {
        rename { "${it}_${project.archivesBaseName}"}
    }
}

// configure the maven publication
publishing {
    publications {
        mavenJava(MavenPublication) {
            from components.java
        }
    }

    // See https://docs.gradle.org/current/userguide/publishing_maven.html for information on how to set up publishing.
    repositories {
        // Add repositories to publish to here.
        // Notice: This block does NOT have the same function as the block in the top level.
        // The repositories here will be used for publishing your artifact, not for
        // retrieving dependencies.
    }
}

Well, a nearly day passed and I figure out what was the problem. I needed to add these things:

configurations{
    addtojar
}
dependencies {
        implementation "com.sparkjava:spark-core:2.9.3"
    addtojar "com.sparkjava:spark-core:2.9.3"
}
jar {
    duplicatesStrategy = DuplicatesStrategy.EXCLUDE
    from("LICENSE") {
        rename { "${it}_${project.archivesBaseName}" }
    }
    from {
        configurations.addtojar.findAll { it.name.endsWith('jar') }.collect { zipTree(it) }
    }
}
