Configuring Source Forge

1. Download a copy of the Source Forge of Minecraft from this link, skipping the ads inside it.

2. Unzip the downloaded file into the project's folder.

   

3. Navigate inside the folder, open a terminal and run this command:

Windows

gradlew setupDecompWorkspace --refresh-dependencies

Linux/Unix

./gradlew setupDecompWorkspace --refresh-dependencies

If the command doesn't work, you must enter this command first: chmod +x gradlew.

IDE

4. After the installation of the gradle is done, we must choose the IDE. We are only showing Eclipse and Intellij, other IDEs are accepted but not listed in this tutorial.

   • For Eclipse, run this command:

     Windows

       gradlew eclipse
     

     Linux/Unix

       ./gradlew eclipse
     

   • For IntellijIDEA, you must open the IDE and import the project. Then, run this command:

     Windows

       gradlew genIntellijRuns
     

     Linux/Unix

       ./gradlew genIntellijruns
     

5. Open the IDE you are working with and import the generated proyect.

   • If you are using Intellij and found a problem running the project. You must:

     • Go to Run/Edit Configurations.
     • Go to Application/Minecraft Client
     • In the Use classpath of module section, switch the package to <Name of Project>_main and click on Apply.
     • Do the same steps for the Minecraft Server.

     

JSon Simple

6. Now you need JSon Simple to contribute generating the height maps. You can download it here.

   • Include it as a project depency.

7. Run the project.

Getting MarCraft Source

Now we need MarCraft source.

1. We need to install Git; you can get it here:
2. Open the directory folder and navigate to the src/main folder. Inside it, open a Terminal and run this command: git clone https://github.com/oscaresgil/marcraft
3. This will clone the MarCraft Source, but it's necesary to remove some things first: Navigate into the marcraft downloaded folder. Move the java and resources folders into the upper directory (src/main), and then remove the marcraft downloaded folder.
4. Run the updated project.
