From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Minecrell Date: Fri, 9 Jun 2017 19:03:43 +0200 Subject: [PATCH] Use TerminalConsoleAppender for console improvements Rewrite console improvements (console colors, tab completion, persistent input line, ...) using JLine 3.x and TerminalConsoleAppender. New features: - Support console colors for Vanilla commands - Add console colors for warnings and errors - Server can now be turned off safely using CTRL + C. JLine catches the signal and the implementation shuts down the server cleanly. - Support console colors and persistent input line when running in IntelliJ IDEA Other changes: - Server starts 1-2 seconds faster thanks to optimizations in Log4j configuration diff --git a/build.gradle.kts b/build.gradle.kts index cfdb20447e6ad3efcdee8889712f77931773beaf..d4141a24cb5ba20e8c53c85206b32120ff18eb48 100644 --- a/build.gradle.kts +++ b/build.gradle.kts @@ -8,7 +8,17 @@ plugins { dependencies { implementation(project(":paper-api")) - implementation("jline:jline:2.12.1") + // Paper start + implementation("org.jline:jline-terminal-jansi:3.21.0") + implementation("net.minecrell:terminalconsoleappender:1.3.0") + /* + Required to add the missing Log4j2Plugins.dat file from log4j-core + which has been removed by Mojang.
