Cache Maven distribution downloaded by Maven Wrapper #448
Description
Description:
Cache the Maven distribution downloaded by the official Maven Wrapper.
The cache key should probably be derived from the .mvn/wrapper/maven-wrapper.properties file (see documentation), similar to how it is done already for the Gradle Wrapper.
The directory to cache is ~/.m2/wrapper/dists (see documentation).
Justification:
Without caching, projects using the Maven Wrapper would have to download the Maven distribution (~8MB) every time the project is built.
For Gradle the setup-java action already supports caching the Gradle distribution downloaded by the wrapper:

@yeikel Hi, maybe you can support gradlew also, this is really useful of cache mvnw and gradlew
yeikel commentedon Jul 14, 2023
I think that we should track that separately
seepine commentedon Jul 14, 2023
You are right, maybe not work of cache gradlew due to excessive cache size, i find it work just now.

It looks like Sonatype started enforcing stricter traffic policies when downloading the Maven distros. I have spotted some HTTP 429s when downloading from
