Pants

Purpose: Pants is a fast, scalable, user-friendly build system for codebases of all sizes.
Languages: Pants focuses on Python, Go, Java, Scala, Kotlin, Shell, and Docker.
Tool orchestration: Pants installs, orchestrates, and runs compilers, code generators, dependency resolvers, test runners, linters, formatters, packagers, REPLs, and other tools.
Dependency inference: Pants analyzes import statements to determine file dependencies automatically, reducing manual dependency declarations.
Engine: The Pants engine is written in Rust and its build rules are written in typed Python 3.
Execution: The engine provides concurrency, fine-grained invalidation, hermetic execution, caching, and remote execution.
Plugin API: Custom Pants rules use the Pants plugin API and run with the same concurrency, caching, and remoting semantics as core rules.
Integrations: Built-in support includes Docker, Pex, Protodoc, Thrift, Protobuf, Helm, linting and formatting tools, packaging, and coverage.
Supply-chain security: Pants lockfiles pin transitive dependency versions and expected SHA256 hashes, and Pants verifies downloaded artifacts against those hashes.
Installation: The installer detects operating system and architecture, downloads the appropriate Pants binary, validates its fingerprint, and installs it into ~/.local/bin.
Supported systems: Pants runs on Linux x86_64 or ARM64, macOS 10.15 or newer on Intel or Apple Silicon, and Microsoft Windows 10 with WSL 2.
Community support: The project provides community help through Slack, mailing lists, GitHub, and other community channels.
IDE limitation: Pants does not yet have tight IDE integrations such as a PyCharm plugin or VSCode extension that runs Pants on the IDE's behalf.
Platform limitation: Alpine Linux is not currently supported because Pants is distributed as a manylinux wheel requiring glibc.
