updated 8th Dec, 2025 for 1.21.10
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.
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
-
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.gitYou 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!



they are not charging for the product itself, they are charging for a service... said service is "the compiled tool AND direct support for it", which means you can compile it by yourself if you want, but you WON´T get support for it... that's what an OPEN SOURCE PROJECT is, the code is free for everyone to use it under the condition of crediting them (if you use it on other projects)... no one is "angry" that a dev is making a living from it, you are the one angry because not everyone is willing to pay, I bet you are angry also for people cracking Adobe, poor "indie company making a living out of their shitty software"... deal with it, don't try to play SWJ and make yourself look in the eyes of others, that just makes you pathetic...
