Versions for kotlin, gradle, IntelliJ, Java

[JohnLCaron]

Kotlin
Currently we are using kotlin 1.7.21, (bug fix for 1.7.20 available since 9/29/2022)
This supports IntelliiJ 2021.3, 2022.1, and 2022.2.
Compatible with Gradle 6.7.1 – 7.1.1

A new version of kotlin, 1.8.0 is available since 12/28/22
This supports IntelliJ 2021.3, 2022.1, 2022.2
Compatible with Gradle 6.8.3 – 7.3.3

The kotlin version is set all over the place in build.gradle.kts and settings.gradle.kts (this should be centralized, FIXED see PR#259)

Gradle
The version of gradle is set in gradle/wrapper/gradle-wrapper.properties To check, run

./gradlew --version

Currently using Gradle 7.4.2.
Latest version of Gradle is 7.6
See Upgrade Gradle

Might not be the best thing to get ahead of the currently supported version. Perhaps revert?

IntelliJ

The version of IntelliJ is controlled by user download. Currently I have

IntelliJ 2022.3.1, Dec 20, 2022
Kotlin Plugin 223-1.7.21-release-272 is bundled, supports Kotlin 1.7.20 and lower.

2023.1 is in EAP, not clear what version of kotlin or gradle it will support.

Might not be the best thing to get ahead of the currently supported version.

Java version

By default, the Kotlin/JVM compiler produces Java 8 compatible bytecode.

Starting with version 1.8.0, the compiler can generate classes with a bytecode version corresponding to JVM 19. One must set the target Java version (presumably there should be some efficiencies to do so), in egklib/build.gradle.kts:

kotlin {
    jvm {
        compilations.all { kotlinOptions.jvmTarget = "1.8" }
        //        withJava()
       ....

PR #196 upgraded 7.5.1 to gradle 7.6-rc-1 in order to fix gradle/gradle#22423

PR #203 downgraded to gradle 7.4.2 in order to fix problems with test failures.

[JohnLCaron]

We could try upgrading kotlin to 1.8 and downgrading gradle to 7.3.3.

OTOH, the docs say

Latest Gradle and AGP versions should generally work without issues.

So we could also go back to trying gradle 7.6

Read https://kotlinlang.org/docs/gradle-configure-project.html for lots of confusing details.

[JohnLCaron]

We could try upgrading Java to 11 or 17 and see if theres a performance inprovement.
