Introducing Maven‑mvnd: A Faster Maven Build Tool – Installation, Usage, and Troubleshooting

1. Introduction

Maven‑mvnd is a high‑performance build tool derived from Apache Maven, inspired by Gradle and Takari, that embeds Maven itself so you can switch to mvnd without a separate Maven installation.

It runs a daemon process (or multiple daemons) to serve build requests, achieving parallel builds, and replaces the traditional JVM with GraalVM for faster startup and lower memory consumption.

Compared with classic Maven, mvnd offers several advantages:

The JVM used for a build does not need to restart for each invocation.

Plugin class loaders are cached across builds, so plugin JARs are read and parsed only once.

JIT‑generated native code remains in memory, reducing compilation time on repeated builds.

By default mvnd uses all available CPU cores minus one (Math.max(Runtime.getRuntime().availableProcessors() - 1, 1)) for parallel module compilation; you can force serial builds with -T1 .

2. Installation

The official documentation provides a detailed guide (https://github.com/apache/maven-mvnd). The author installed mvnd via Homebrew on macOS M1, which works but installs version 0.7.1 that does not support JDK 8.

Running mvnd -v on JDK 8 produces a JNI error because the binary was compiled for a newer Java version (class file version 55.0). The workaround is to set JAVA_HOME to JDK 11 and add the compiler flag -Dmaven.compiler.release=8 :

mvnd -Dmaven.compiler.release=8 compile

This forces the generated bytecode to be compatible with JDK 8. If the issue persists, you may need to build mvnd from source as described in the README.

3. Usage

Usage is identical to Maven; simply replace the mvn command with mvnd . In the author's tests, builds with mvnd took roughly half the time of traditional Maven builds.

The article covered mvnd’s introduction, installation steps, usage pattern, and common pitfalls such as JDK version incompatibility. For more details, readers are encouraged to consult the official documentation.
