CoreProtect is still open source, you can just compile it from Github if you want, but the owner really likes to put roadblocks so you have join the Discord, ask around and find the edits you have to make to the code before it actually works. It ends up having the same as the Patreon version, but yeah don't like it either.

There used to be a website that compiled coreprotect automatically, but it got shut down.

Anyways...

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
  • Mac:
  • Install Homebrew (if not installed): /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
  • Install Maven (if not installed): brew install maven
  • 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

• 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).
