AntiPopup - Paper 26.2 / Java 25 fork

Important

This mrfdev fork is intentionally specialized for Paper 26.2. For the original multi-version and proxy-compatible project, see KaspianDev/AntiPopup.

What is special about this fork?

• Builds a standalone Paper server plugin only; Velocity and the historical Minecraft NMS modules are excluded from the active Gradle project and final artifact.
• Includes only the Paper 26.2 v26.2 injector and declares api-version: '26.2'.
• Compiles every retained project module as Java 25 bytecode. The resulting plugin runs on Java 25 and newer JVMs, including Java 26.0.1.
• Shades its runtime libraries, including PacketEvents, BoostedYAML, bStats, Adventure, and FoliaLib, so no companion dependency jars are required.
• Has been compiled with Gradle 9.4.1 and smoke-tested through a complete enable, Paper 26.2 injector selection, and clean shutdown on Paper 26.2-29-dev with Java 26.0.1.

Building this fork

JDK 25 is required as the Gradle compilation toolchain.

./gradlew clean build

The deployable shaded plugin is written to:

build/libs/AntiPopup-13.2-j25-mc26.2.jar

What is this plugin?
AntiPopup is a plugin aiming to remove chat reporting system entirely using packets. It also has unique feature - blocks the new annoying popup (below) even if your server doesn't enforce chat reporting (please don't enforce it).
My plugin is also the safest to use, chance of breaking a different plugin is unlikely, I'd even say impossible. Note that some plugins might break it, report that to me.

How to install?
Plug and play, nothing else for you to do.
Optionally you can run antipopup setup in console, recommended.
If you use viaversion on bungeecord install AntiPopup ViaVersion addon.

Commands
antipopup setup - Disables enforce-secure-profile in server.properties (console only).
antipopup reload - Reloads configuration.

Faq
Q: What if my server runs an older version?
A: If you use viaversion and antipopup, 1.19.1+ players will not see popup.
Q: Will it work with ViaFabric?
A: Popup will be shown for 1.19.2 clients spoofing to 1.19, nothing I can fix on my side.
