Mvnd Cuts SeaTunnel Build Times by Over Half

In large-scale data integration projects, build performance is critical. This article benchmarks Apache SeaTunnel using traditional Maven versus the next-generation build tool, Maven Daemon (mvnd). The results show that mvnd delivers approximately 60% faster builds by leveraging background daemons and multi-threaded execution. Better yet, it’s fully compatible with existing projects—no changes to pom.xml needed. Installation steps, usage guides, and performance comparisons are included—try it now to supercharge your workflow!

What Is Maven Daemon (mvnd)?

Maven Daemon (mvnd) is a wrapper around Maven that keeps the JVM running in the background between builds, significantly reducing startup overhead.

Key Features of mvnd

1. Faster Build Speeds – Eliminates repeated JVM startup costs.
2. Parallel Builds – Takes advantage of multi-core CPUs.
3. Seamless Compatibility – Works with existing Maven projects with no pom.xml modifications.
4. Incremental Build Awareness – Detects changes and minimizes unnecessary recompilation.

How to Install

1. Download the binary from the mvnd download page
2. Unzip the archive and add the bin/ directory to your system PATH
3. Verify with:

mvnd -v How to Use

Run mvnd like you would Maven:

mvnd clean install

Specify threads if needed:

mvnd --threads 4 clean install Performance Comparison

Traditional Maven:

mvn clean install

With mvnd:

mvnd clean install SeaTunnel Build Test Results mvn clean package -pl :seatunnel-dist -am -D"skip.ui"=true -DskipTests -Prelease

mvnd clean package -pl :seatunnel-dist -am -D"skip.ui"=true -DskipTests -Prelease

mvn clean package -pl :seatunnel-dist -am -D"skip.ui"=true -DskipTests

mvnd clean package -pl :seatunnel-dist -am -D"skip.ui"=true -DskipTests

Based on these benchmarks, Maven Daemon significantly outperforms traditional Maven in the SeaTunnel project’s build and packaging processes. By reusing the JVM and executing tasks in parallel, mvnd can reduce build time by up to 60%.

Developers benefit from instant productivity gains, seamless integration into existing workflows, and a faster feedback loop—without touching a single line of project config. If you’re building large-scale, module-rich projects like SeaTunnel, adopting mvnd is a no-brainer.
