Discord Integration Project

New features · Prejoin verification (DiscordSRV-style) — optional. Unregistered players are kicked with a one-time code; they run +confirm <code> (or /confirm) on Discord and reconnect. Already-registered players get a DM with Approve / Deny buttons. AuthMe is integrated — the password is DM'd and applied on next join. · FastLogin premium bypass — verified Mojang account owners skip the Discord flow. Secure at the protocol level (cannot be spoofed by name). · Multi-language — set language: es in config to load lang_es.yml. Spanish bundled out of the box; any locale supported via lang_<code>.yml. · Auto-updating server status embed in a Discord channel — online players, MOTD, TPS, uptime. Edits the same message every N seconds, no spam. · Whitelist gate — admins approve / deny join requests directly from a Discord embed with buttons. · Welcome DM sent once on first successful registration. Configurable. · Config auto-merge — upgrades append new keys to your config.yml without regenerating it. Your values are preserved. · Cross-server identity — multiple Bukkit servers can share a single MySQL DB. A player registered on server A is recognised on server B without re-linking Discord. · Configurable bot activity — PLAYING, WATCHING, LISTENING, COMPETING, STREAMING with live placeholders (%minecraft_players%, %minecraft_max_players%, %minecraft_motd%, %server_name%). · Limbo mode (opt-in) — players awaiting verification go to spectator + invisible + chat-muted so they cannot disrupt other players. Stability & security · Critical CVE in MySQL connector patched (mysql-connector-j 8.4.0) · JDA bumped to stable 5.0.2 · Real HikariCP connection pool for MySQL and SQLite (with WAL on SQLite) · Discord token auto-redacted in logs ([REDACTED_DISCORD_TOKEN]) · Anti-DoS rate limit on prejoin verification (5 attempts / IP / minute, 1000-entry hard cap) · Schema version guard prevents an older plugin from corrupting a DB already migrated by a newer one · Eager config validation at startup — lists every missing required key in one pass · Clean JDA shutdown on plugin disable (no more "zip file closed" errors) · JDA classes shaded under di.shaded.jda — no more conflicts with Vixio, DiscordSRV or other plugins that bundle their own JDA copy · DM coordinator coalesces Discord DMs per recipient to avoid hitting per-user rate limits Bug fixes · Roles not granted after registration (giveRole did not handle null role and queue() had no error handler) · Cascading "zip file closed" errors when the config was incomplete · "Server is not fully started" when using FastLogin (DILogin now registers as FastLogin's auth-plugin via reflection) · Click-to-copy on the register message did not work on MC 1.18+ (version parser only knew up to 1.17) · NullPointerException in TmpCache during PlayerJoinEvent (ConcurrentHashMap rejects null values — sentinel pattern now) · SQLite pool starvation at startup caused by an initial connection leak · Race conditions in concurrent caches · Connection leaks in the DAO (missing try-with-resources) · "Users" header in +userlist was not translatable — now lives in lang.yml Developer experience · bStats integration (Spigot ID 31219, Bungee ID 31220) · 22 unit tests run in CI · PR validation workflow runs mvn verify on every pull request · /confirm slash command in addition to +confirm · api-version: '1.13' in plugin.yml — silences the "Legacy plugin" warning · release-please automates the changelog and release pipeline Installation Drop the following jars into your server's plugins/ folder: · DICore-4.5.0.jar — default. Bundles SLF4J + log4j so JDA logs work out of the box. · DICore-4.5.0-noslf4j.jar — use if your server already exposes SLF4J (modern Paper, Velocity, hybrid). Loading two SLF4J copies would cause LinkageError. · DILogin-4.5.0.jar — registration & login system. · DILitebansLogs-4.5.0.jar — optional, sends LiteBans punishments to Discord. Direct upgrade from 4.4.0 — config auto-merge appends the new keys for you without touching your existing values. No manual migration needed.
