Solved I can't compile my 1º plugin

i followed the guide "Plugin Tutorial" for make a basic plugin (Called "ayuda").

So I've these files:

The file Pom.xml:

Code:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <groupId>com.mi.email</groupId>
  <artifactId>ayuda</artifactId>
  <version>0.0.1-SNAPSHOT</version>
     <build>
      <plugins>
          <plugin>
              <groupId>org.apache.maven.plugins</groupId>
              <artifactId>maven-compiler-plugin</artifactId>
              <configuration>
                  <source>1.7</source>
                  <target>1.7</target>
              </configuration>
          </plugin>
      </plugins>
   </build>
      <repositories>
       <repository>
         <id>spigot-repo</id>
         <url>https://hub.spigotmc.org/nexus/content/groups/public/</url>
       </repository>
   </repositories>
      <dependencies>
       <dependency>
           <groupId>org.bukkit</groupId>
           <artifactId>bukkit</artifactId>
           <version>1.8-R0.1-SNAPSHOT</version>
           <type>jar</type>
           <scope>provided</scope>
       </dependency>
   </dependencies>
</project>

The principal Class:

Code:

package com.miemail.ayuda;
import org.bukkit.plugin.java.JavaPlugin;
public class ayuda extends JavaPlugin{
    public void onEnable(){
        getLogger().info("Se ha activado el plugin");
        this.getCommand("ayuda").setExecutor(new EjecutarComando(this));
    }
    public void onDisable(){
        getLogger().info("Se ha desactivado el plugin");
    }
}

And another Class (CommandExecutor):

Code:

package com.my.email.ayuda;
import org.bukkit.command.CommandSender;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.entity.Player;
public class EjecutarComando implements CommandExecutor {
    private final ayuda plugin;
    public EjecutarComando(ayuda plugin){
        this.plugin=plugin;
    }
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){
        if(cmd.getName().equalsIgnoreCase("ayuda")){
            if(sender instanceof  Player){
                Player player = (Player) sender;
                sender.sendMessage("Bien");
            }else{
                sender.sendMessage("¡Este comando es para jugadores!");
            }
            return true;
        }
        return false;
    }
}

Then i've the plugin.yml:

Code:

    name: ayuda
    main: com.my.email.ayuda.ayuda
    version: 1.0
    commands:
      ayuda:
        description: Ver comandos disponibles.
        usage: /ayuda <pagina>
        permission: sm.ayuda
        permission-message: No puedes hacer eso.

And the error when i do "Run as>7 Maven generate-sources:

Code:

What does it mean?

Solved
I needed to add the <version> in the pom.xml file:

Code:

<plugins>
          <plugin>
              <groupId>org.apache.maven.plugins</groupId>
              <artifactId>maven-compiler-plugin</artifactId>
              <version>2.3.2</version>
              <configuration>
                  <source>1.8</source>
                  <target>1.8</target>
              </configuration>
          </plugin>
      </plugins>

 

Instead of getLogger you can use(If is easier)> System.out.println("Any text here to print to console.");
Please follow java naming conventions(Main class doesn't start with a capital).
I can't help you with building as I just export my plugins.

 

Thanks you for the advice.

 

Um, it says "BUILD SUCCESS" right there in the maven output. The rest is just maven being cranky.

 

That is just Maven being cranky that the OP didn't specify a version for the compiler plugin. You can generally ignore those, unless you create some very hacky crap code that requires a special version of a maven plugin.
