Depo
A universal dependency manager for Spigot/Paper plugins



​

What is Depo?
Depo automatically detects missing plugin dependencies on your server and fetches them from trusted sources so you don’t have to. On startup it scans your /plugins folder, reads plugin.yml depend/softdepend, and (optionally) downloads missing dependencies into /plugins/.

Key points
  • Scans installed plugins and collects depend: and softdepend:
  • Resolves and downloads dependencies from Modrinth (preferred) and Spiget (fallback)
  • Respects platform (Purpur/Paper/Spigot) and MC version when querying Modrinth
  • Configurable: auto-download, soft dependency policy, version constraints, categories, download progress, repository priority, overrides, aliases, HTTP timeouts, colored logs, i18n via messages.yml
  • Manual install commands: direct URL and GitHub latest release (shortcuts: /depo s, /depo dl)
  • Async scanning/downloading — does not block server startup
  • Persistent install log at plugins/Depo/installed.log
  • Optional SHA-256 checksum validation (per plugin)
  • Version constraints & dependency tree visualization (/depo tree)
  • Conflict detection & interactive resolution (/depo resolve)
  • Optional (soft) dependencies listed separately; selective install via /depo soft (not auto-downloaded by default)
  • Numbered soft dependency list with multi-select install (indices or names)
  • Download progress feedback (throttled)
  • Update checker (notify-only)
  • Metrics via bStats (configurable)
  • Security toggle to block non-HTTPS downloads
  • No hot-loading — restart required after installs



Supported
  • Engines: Purpur, Paper, Spigot (Bukkit-compatible)
  • Java: 17+
  • MC: 1.20.x and newer (where API-compatible)



Installation
  1. Place Depo.jar into your server’s /plugins folder.
  2. Start the server once to generate plugins/Depo/config.yml.
  3. (Optional) Adjust config: repository priority, overrides, aliases, checksums, colored logs, security.
  4. Restart if Depo installs anything (it never hot-loads).



How it works
  • Depo scans all JARs in /plugins, reads plugin.yml, and builds a required dependency set.
  • It compares against installed plugin names plus any provides: entries and configured aliases.
  • Missing dependencies are resolved using Modrinth (filtered by loader + MC version) then Spiget.
  • Downloaded JARs are validated to contain a matching plugin.yml (name or provides); optional checksum can be enforced.



Commands
  • /depo status — Summary including categories, conflicts, queue, and separated soft dependencies.
  • /depo reload — Reloads Depo config.
  • /depo download direct <url> — Download a JAR from a direct link (validated, no hot-load).
  • /depo download github <owner/repo> [assetFilter] — Download the first matching .jar from GitHub’s latest release (optionally filtered by asset name).
  • /depo tree — Show per-plugin declared dependencies with constraint annotations.
  • /depo resolve <dependency> <ignore|relax|override <url>> — Manage version conflicts.
  • /depo soft list — List optional (soft) dependencies with numbering.
  • /depo soft install <index|name|all|comma,list> — Install one, many, or all optional dependencies.

Shortcuts
  • /depo s — status
  • /depo dl — download

Permissions
  • depo.use — Use base commands (default: op)
  • depo.notify — Receive install notifications (default: op)
  • depo.download — Parent for download subcommands (default: op)
  • depo.download.direct — Use /depo download direct (default: op)
  • depo.download.github — Use /depo download github (default: op)



Configuration
Code (YAML):

# If false, Depo only logs missing dependencies and will not download them.
auto-download : true

# If true, soft dependencies (softdepend) are also auto-downloaded.
auto-download-soft : false

# Optional automatic update of already-installed dependencies (reserved for future use).
auto-update : false

# Repository priority. Valid values: [modrinth, spiget]
repository-priority :
  - modrinth
  - spiget

# Manual overrides for specific dependency names -> direct JAR URL
overrides : { }

# Aliases: treat a dependency name as provided by another installed plugin name
aliases : { }

# Optional checksums: map plugin name to lowercase hex SHA-256 to validate downloads
checksums : { }

# Semantic version constraints
version-constraints : { }

# Optional plugin categories (for status grouping)
categories : { }

# Show download progress (approximate) in console for large files
download-progress : true

# HTTP timeouts (ms)
http:
  connect-timeout : 10000
  read-timeout : 30000

# Colored console output
colored-logs : true

metrics:
  enabled : true
  service-id : 0

update-checker:
  enabled : true

security:
  block-insecure-downloads : true

config-version : 4
 



Examples
  • Auto-resolve: Start server; Depo will report and download missing dependencies (if auto-download is true).
  • Manual direct: /depo download direct https://example.com/Plugin-1.0.jar
  • Manual GitHub: /depo download github Owner/Repo paper (filters asset name containing "paper").
  • Aliases: If a plugin provides Vault under a different name, map it:
    Code (YAML):

    aliases    :
      Vault     : ComplexVault
     



Safety
  • Trusted sources only: Modrinth (preferred), Spiget (fallback)
  • Validates plugin.yml inside downloaded JAR (name/provides must match)
  • Optional checksum verification per plugin
  • Security option to block plain HTTP URLs
  • No hot-loading — restart required



Troubleshooting
  • A dependency keeps re-downloading — ensure another plugin isn’t already providing it. Use aliases to map the required name to the installed provider, or ensure the provider’s plugin.yml includes provides:.
  • Nothing downloads — set auto-download: true, check network, and review console for Depo logs.
  • GitHub asset not found — specify an assetFilter matching the .jar asset name.



Notes
  • Depo is designed for admins who want consistent dependency resolution without hunting links.
  • Auto-update is intentionally disabled by default and not yet implemented.
