Problem compiling Jar

when i build it tells that class extends or implement other class but it’s not true

package it.pizzadev.sorter.bukkit.api.matchmaking.destination;

import it.pizzadev.sorter.bukkit.api.matchmaking.types.MatchServerType;
import lombok.Getter;

@Getter
public class MatchInformation {

    private final MatchServerType serverType;

    private final int serverNumber;
    private final int matchNumber;

    public MatchInformation(String serializable) {
        String[] split = serializable.split("/");
        serverType = MatchServerType.valueOf(split[0]);
        serverNumber = Integer.parseInt(split[1]);
        matchNumber = Integer.parseInt(split[2]);
    }

    public MatchInformation(MatchServerType serverType, int serverNumber, int matchNumber) {
        this.serverType = serverType;
        this.serverNumber = serverNumber;
        this.matchNumber = matchNumber;
    }

    public String serialize() {
        return serverType.name() + "/" + serverNumber + "/" + matchNumber;
    }

    @Override
    public MatchInformation clone() {
        try {
            return (MatchInformation) super.clone();
        } catch (CloneNotSupportedException e) {
            throw new AssertionError();
        }
    }
}

tasks.register('proguard', proguard.gradle.ProGuardTask) {

    dependsOn(shadowJar)
    configuration file('proguard.pro')


    injars(tasks.named('shadowJar', Jar).flatMap { it.archiveFile })

    verbose

    outjars(layout.buildDirectory.file("libs/${project.name}-${project.version}-OBF.jar"))
}
