Tutorial of Downloading and Building the CoreProtect Plugin

This tutorial will explain from nothing how to build/create the CoreProtect plugin or 1.21.10 from it's source code on GitHub.

I am assuming you don't know anything and don't have anything installed and are using a Windows device.

Prerequisites

Watch these tutorial videos (very short).

• You must use Java JDK 21. Download here. https://adoptium.net/temurin/releases/?version=21&os=windows&arch=x64
• Install Maven on Windows 11 https://www.youtube.com/watch?v=YTvlb6eny_0
• Install Git https://www.youtube.com/watch?v=cJTXh7g-uCM

Start Compiling

• Right click the "Start" or "Windows" icon on your taskbar.

• Click "Command Prompt".

• Type the following commands.

cd Desktop
git clone https://github.com/PlayPro/CoreProtect.git

AFTER USING GIT CLONE

You need to go to Desktop\CoreProtect\pox.xml Right click the file, click Open With > Notepad.

Change <project.branch></project.branch> to <project.branch>developer</project.branch>

In the same Command Prompt window, type the following:

cd CoreProtect
mvn clean install

This process will take a while. You should see [INFO] BUILD SUCCESS when it is complete.

The plugin jar will be outputted in the FOLDER NAME\target\CoreProtect-version.jar

Do not use the .jar labelled "original".

I am not paying for your patreon for builds to open source. Thank you & have an amazing day! Be cautious of build download links under this comment section!
