Bloom 0.1.0

First public release of Bloom: one plugin jar for Minecraft 1.7.10 – 1.8.9 and Paper 1.21.1 – 26.3.x.
Verified on real PaperSpigot 1.7.10 and 1.8.8 and Paper 1.21.11 and 26.3 servers.

Using this release

Bloom 0.1.0 is not on Maven Central yet. bloom-0.1.0-central-bundle.zip is a Maven repository: unzip it and add
it to your plugin's build.gradle.kts:

repositories {
    maven(uri("path/to/bloom-0.1.0-repo"))  // the unzipped bundle
    // ... spigot / papermc repositories, see the installation guide
}
dependencies {
    implementation("io.github.crownalonedev.bloom:bloom-gui:0.1.0")
    runtimeOnly("io.github.crownalonedev.bloom:bloom-legacy:0.1.0")
    runtimeOnly("io.github.crownalonedev.bloom:bloom-modern:0.1.0")
}

Shade and relocate Bloom as shown in bloom-examples/template, then check your jar:
java -jar bloom-doctor-0.1.0-all.jar build/libs/your-plugin.jar.

Also attached: the six example plugins (drop into plugins/), the API manifest and SHA256SUMS.

Added

• bloom-api, bloom-common, bloom-bukkit: Bloom entry point, platform detection and support policy, capabilities, services, lifecycle, scheduler, messages (chat, action bar, title, boss bar) with an unsupported-feature policy, event subscriptions, cooldowns, durations, caches.
• Platform adapters: bloom-legacy for 1.7.10 – 1.8.9 and bloom-modern for Paper 1.21.1 – 26.3.x.
• bloom-items: item builder, modern ↔ legacy material names, item flags, persistent item data, custom items, serialization.
• bloom-gui: inventory menus with buttons, layouts, templates, pagination, back navigation, confirmation and per-player state.
• bloom-config: YAML configuration with defaults, typed getters with line-numbered errors, validation, object mapping, migrations with backups.
• bloom-storage: asynchronous SQLite, MySQL and MariaDB access with pooling, transactions, migrations and repositories.
• bloom-testing: manual scheduler and test clock.
• Example plugins, a standalone template project, a real-server self-test harness (run.sh, run.bat) and the documentation website.
• bloom-doctor: checks plugin jars (plugin.yml, relocation, adapters, Java level) and verifies every Bukkit/Paper reference against target server APIs.
• API manifest (./gradlew apiManifest), API reference page, llms.txt, AGENTS.md and a Claude Code skill for plugin authors.

Security

• Legacy Items.deserialize only resolves the classes an item consists of instead of any serializable class.
• Untrusted Placeholder.of values can no longer inject section-sign formatting into MiniMessage messages.

Fixed

• SQLite on 1.7.10 and 1.8.x servers, whose bundled sqlite-jdbc 3.7.2 rejected the WAL setting and lacks Connection.isValid.
• Persistent item data was lost on 1.7.10 when the item was copied back to a Bukkit stack.
