Speed Up Your Maven Build x10…Before You Move to Gradle
Gradle has a lot of performance advantages in comparison to Maven. But there are still several ways to speed up Maven builds.
Simple:
- Upgrade hardware, upgrade JDK, use proper JDK for your arch (e.g. Apple Silicon)
- Parallel execution, “mvn -T1C” in .mvn/maven.config
- maven.test.skip=true (relates to get rid of test-jar dependencies)
- Kotlin K2 compiler
- Develocity Extension
Middle:
- Stop deploying redundant artifacts on each build
- Split large modules to smaller (explanation why it makes sense, comparison with Gradle)
- Remove redundant dependencies
- Get rid of “test-jar” dependencies
- Extract code generation to jar dependency
Complex:
- Get rid of AspectJ compiler (25% of compile time)
Paid:
- Develocity with remote cache
Additional topics:
- mvnd as way to visualize parallelization bottlenecks (alternate to Develocity or other plugins)
- IDEA: parallel compilation
- Eventually migrate to Gradle to have new opportunities. Some advice for Maven works for Gradle projects as well
