## What it is
Apache Maven Daemon (mvnd) is a drop-in replacement for the Maven build tool that runs builds in a long-lived background daemon process. It leverages the daemon to keep the JVM and classloader caches warm, dramatically speeding up repeated Maven builds.

## Use cases
- speed up maven builds
- faster java build times
- avoid jvm startup overhead in maven
- run maven builds with parallel execution
- drop-in replacement for mvn
- reduce build times in ci and local development

## When to choose
- you use Maven for Java builds and want faster incremental builds
- you run mvn repeatedly during development and want warm JVM caching
- you want a mostly drop-in mvn-compatible CLI with parallel builds

## When to avoid
- your build environment cannot keep a daemon process alive (e.g. some CI setups)
- you rely on strict per-invocation JVM isolation or Maven features incompatible with the daemon
- you use a different build system like Gradle

## Facets
- artifact type: cli-tool
- maturity: active
- function: build-tool, cli, developer-tools
- domain: developer-tools
- platform: windows, jvm, cli, cross-platform
