Switch to Maven

[andreaTP]

@ErikSchierboom for now I dropped the "colorization" of the output, feel free to suggest an appropriate command if you prefer to have it back 🙂 , also doublecheck my results please 🙏

side note, we can test something like:

export JAVA_TOOL_OPTIONS="-Xss128m -Xms256m -Xmx2G -XX:+UseG1GC"

even in the java-runner.

This is fantastic! On my Macbook, the run time goes from 19 seconds to 9 seconds!

I added 1019932 for the colorization.

@andreaTP Same question as for the Java change: is this safe to merge?

Wow, @ErikSchierboom we do have seriously different machines! On mine, I had a much smaller improvement here (3-4 seconds).

is this safe to merge?

The answer is: "It should be" 🙂 , in the repo: https://github.com/exercism/groovy 55 out of 55 build.gradle files contain:

dependencies {
    testImplementation "org.spockframework:spock-core:2.0-M2-groovy-3.0"
    implementation "org.codehaus.groovy:groovy-all:3.0.2"
}

with maven we are bumping a little the versions (within the semver boundaries):

groovy -> 3.0.8
spock -> 2.0-groovy-3.0

Probably it would be good to do(at least) the version bump in the exercises repo too, but all of this is supposed to be safe.

So even without the version bump in the exercises, they'll run successfully on the test runner?

everything I tested is running as expected, so, at best of my knowledge, yes 👍

[ErikSchierboom]

Merging! Thanks @andreaTP

[ErikSchierboom]

@andreaTP I've just tested, and I had a 10 seconds test run for hello-world, so that's great! Can this (using Maven) also be applied to Kotlin?

[andreaTP]

@ErikSchierboom very likely, I will try to have a look, great that is working! Do you have stats of overall timeouts (even for java)?

[ErikSchierboom]

@andreaTP I don't think we're keeping track of the execution time yet. I think it is somewhere on my todo list :)

@andreaTP You're a lifesaver!
