Maven not running with Spigot

问题


I'm trying to use MongoDB in a Spigot 1.16.1 Plugin and I'm having Problems with my maven imports.

In my IDE (EclipseIDE) there are no Errors. If I export the Plugin and reload the Server the following error appears:

pom.xml

    @Override

        // MongoDB Connect
        
        MongoDBHandler.connect();


        // Start Plugin Message

        Bukkit.getConsoleSender().sendMessage("§b§l  _            §r§3 ___           __ _        _        ___               _    _      ___       _ _          ");
        Bukkit.getConsoleSender().sendMessage("§b§l | |   ___ ___ §r§3/ __|_ _ __ _ / _| |_   __| |___   / __|___ _ _ ___  (_)__| |_   / _ \\ _ _ | (_)_ _  ___ ");

        Bukkit.getConsoleSender().sendMessage(" ");

        // Listener Register

        getServer().getPluginManager().registerEvents(new JoinListener(), this);

    }

}

I already tried to import the libary with a .jar file but that didn't worked too.

Any help is appreciated

Use the Maven Shade Plugin to include the dependency in your jar.

You should use the maven-assembly-plugin for creating a "fat" jarfile, example:

<plugins>
      <plugin>
        <!-- NOTE: We don't need a groupId specification because the group is
             org.apache.maven.plugins ...which is assumed by default.
         -->
        <artifactId>maven-assembly-plugin</artifactId>
        <version>3.3.0</version>
        <configuration>
          <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
          </descriptorRefs>
        </configuration>
        <executions>
          <execution>
            <id>make-assembly</id> <!-- this is used for inheritance merges -->
            <phase>package</phase> <!-- bind to the packaging phase -->
            <goals>
              <goal>single</goal>
            </goals>
          </execution>
        </executions>
        [...]

This makes sure that every dependency with scope compile gets shaded into a jar file, it should be called (project name and version)-jar-with-dependencies.jar Note that you should set the scope of spigot to provided, because it is already loaded on runtime. Compile using mvn package.

PS: You should never import jars to the classpath using Idea/some other ide if you are using maven, import all your dependencies using Maven.
