Tutorial of Downloading and Building the CoreProtect Plugin

This tutorial will explain from nothing how to build/create the CoreProtect plugin or 1.21 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\src\main\resources\plugin.yml and open the "plugin.yml" file in Notepad.

Change branch: ${project.branch} to branch: developement on line 4.

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".

Does anyone know how to get version V23.2 RC3?

Just change some values in the following files:

build.gradle
[line 10] String projectVersion = '22.4' → String projectVersion = '23.2'

pom.xml
[line 5] 22.4 → 23.2
[line 7] <project.branch></project.branch> → <project.branch>master</project.branch>

Does anyone know how to fix this? theres more errors below that but it just says that a class is the wrong version and that it should be 61.0 instead of the current 65.0

it is trying to compile using java17
change your default java to 21

thats weird... i downloaded java 21 and changed the path thing, ill try it again thanks

Still didnt work

hmm try using openjdk and not temurin

jdk21-openjdk 21.0.6.u7-2
this version worked for me
but i am on linux so not sure about windows
i can send you the compiled file if you want

jdk21-openjdk 21.0.6.u7-2 this version worked for me but i am on linux so not sure about windows i can send you the compiled file if you want

thanks, ill try that

it still didnt work... could you please send me the compiled file? thanks

nevermind... just fixed the issue, make sure to set the system variable 'JAVA_HOME' to java version 21, not just the path one, and verify it with mvn --version

Question for you, I can't find a build.gradle file in the repo, is that normal?

why are we even arguing about compiling a free open source project?

Its only free until Version 1.20.6, and 1.21.x is Paid

still, it's open-source which mean anyone can compile it if they want to. just like plotsquared.

People just can’t stand it that a developer charges money for their own god damn work. And are of the opinion that if it’s given for free before that the developer owes them to keep it free.

— A fellow developer’s perspective.

They even give instructions how to compile it on their own discord. If they dont want people to have this option they would not allow it.

they let people choose: pay monthly for maximum comfort or compile it.

what a stupid discussion here…

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...

I'll put a end to the madness that is this debate:

Essentials, which is MUCH bigger plugin than CoreProtect, supplies dev builds for 1.21 free of charge and the plugin is, I'll shock all of you, well, alive and frequently updated (more than CO) despite having no paywalls! Crazy, ikr?!

Paywalls are not the way to go, it only drives people away.

There are stuff that we call "donations", "kindness", "generosity", etc. that you all seems to forget.

So? GitHub is also free to use and frequently updated, but still charged for more premium features and services. Besides, CoreProtect doesn’t really have a paywall, when it’s free to download if you want to put effort into compiling it yourself. Just the precompiled version, that is behind a paywall (which seems reasonable to me, especially if it’s not that expensive anyway).
