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!

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).

build.gradle

I cant find it either I was wondering if someone else has found it

This was removed a couple of months ago, miss fortune.

so there's no way to to compiled the coreprotect?

Currently, it seems to work to simply change
pom.xml
[line 7] <project.branch></project.branch> → <project.branch>development</project.branch>

no need to touch plugin.yml.
at least for coreprotect version 23.0, minecraft version 1.21.10

Also works for branch master as the plugin was taken from branch master:)

Then use mvn clean package

Here is a CoreProtect compiled edge build v23.3 jar with all metrics/tracking removed and a functional /co migrate-db

Full functionality with latest bugfixes for 1.21.10 with no donation key required or developer tracking.

I am not entitled to your trust and you are welcome to scan the jar file for any malware/backdoors, decompile it if you don't trust this download.
Coreprotect v23.3 Patched.jar

@joex92 @TheDogg @jozlod @Dreadonator @ScuroK Thank you for your contribution to the comment section of this gist. The post has been updated to reflect new changes.

Prebuilt version of the plugin does not work on 1.21.0 at all. So shameful... I think "pleasepayformypatreon" guy should have been announced this tutorial instead of uploading completely broken jars.

Weirdly enough there seems to be a 1.21.10 download now available to the public.

All the backlash seems to have changed their minds, although at the time of writing this the new jars are not on Modrinth or SpigotMC and are only available on Patreon's site.

1.21.11 "early access" is still behind a paywall though.

TLDR this is a fake v23.3 version and FALSE ADVERTISING
This is not the v23.3 build that is on patreon and works with 1.21.11. The version of the build has been modified to correspond to 23.3 but is in fact version v23.1 without .11 support or bug fixes. (It may work on 1.20.11. But does NOT SUPPORT it because the latest patches were gatekept by developer and were not published to community edition repo)

Refer to this link for the actual premium prebuilt version v23.3 which supports 1.21.11

Lmao no build log, no public repo? Yes trust this malicious build quite literally from a random dude on GitHub over our legit build. Hilarious. Stop spreading infected crap.

DON'T TRUST ME, Decompile my prebuilt jar, check for backdoors/viruses/suspicious behaviour YOURSELF. There is no obfuscation at all, all code is plainly visible after decompilation. Check it out. You will find it to be completely clean if you do.

jeez y'all still yapping arguing about this to this day?

JDK 25 is required now btw

I recommend that you join the official CoreProtect discord, the build instructions are posted there and this is where you can find the updated steps.

Taken from discord:

Compilation instructions:
Install Maven and Java 25 if you don't have it already
Linux: sudo apt install maven (or whatever package manager you have )
Windows: Watch this tutorial https://www.youtube.com/watch?v=XEphzGQz-nI
Check with mvn --version that it's installed, and using java 25

Download the source code
You can download the zip manually from GitHub, under the green button labelled "<> Code".
After downloading it, extract it.
Or if you have git with git clone https://github.com/playPro/coreProtect

Open the CoreProtect folder you just created

Set the branch to development
Locate the "pom.xml" file, and open it with a text editor.
Locate where it says<project.branch></project.branch>
Set it to be <project.branch>development</project.branch>

ONLY IF YOU NEED 26.1 SUPPORT:
Navigate to src/main/java/net/coreprotect/config/
Open the "ConfigHandler.java" file with a text editor
On line 56, set the LATEST_VERSION string to 26.1.2
It should look like this: public static final String LATEST_VERSION = "26.1.2";

Open a terminal in the coreprotect folder
On windows you can click the explorer path bar and type cmd, this will open a command prompt at the location.
Please note you have to be in the CoreProtect folder, not any subfolder, not the external folder either
If you are on Linux i assume you know how to do this

In the terminal run the command mvn clean install

If you see a class file has wrong version error, it means you have not installed java 25. Install it and make sure to change your environment variable for JAVA_HOME. Check again with mvn --version

You should now find "CoreProtect-23.2.jar" in the target/ folder.

Note:
While the file will say it's 23.2, it is functionally equivalent to the 24.0 Patreon version, and will work in 26.1 and 26.1.2 (if you changed the files).

You should credit @guss-alberto for this :(

I never said I wrote those steps myself, how am I supposed to know the discord author's github handle?

all your comments on this issue bring absolutely nothing to the subject, maybe you should just mind your own business
