Support Java > 15 and Datanucleus 6 about datanucleus-gradle-plugin HOT 9 OPEN

Thanks for reporting this. Interested in opening up a PR for this?

from datanucleus-gradle-plugin.

To be honest, I have a running version of your plugin with Datanucleus 6, Java 17 and gradle 8.1.1 on Windows.
For Windows I had had to change some path handling in tests ('/' vs. '\').
I had fixed some Closure to Closure<?> too.
I think the new version will not work for Datanucleus 5 any longer.
To get my version deployable for all I need to backport it to Java 11.
Should I try it?
Which gradle wrapper version should I use (8.2.1?)?

from datanucleus-gradle-plugin.

The plugin is still being built with Java 8, in CI.

Datanucleus 6 needs Java version 11 at least

from datanucleus-gradle-plugin.

What version Datanucleus needs is not a requirement for Gradle/plugin, in any case just saying the minimum version the plugin is currently targeting (I don't mind the bump, already using newer Java versions than 8).

from datanucleus-gradle-plugin.

If I revert the java.toolchain.languageVersion to 8 I get

bad class file: ...\datanucleus-core-6.0.4.jar(org/datanucleus/store/schema/SchemaTool.class)
    class file has wrong version 55.0, should be 52.0

So I think we do need Java 11 to support Datanucleus 6.

That assumes the plugin would not be updated to allow to specify a toolchain for Datanucleus tasks.

from datanucleus-gradle-plugin.

Do you talk about an additional toolchain for Datanucleus tasks?
Can you please explain how this could work and why we would need this?

Every project using Datanucleus 6 will need Java 11 at least.
So every user of datanucleus-gradle-plugin for Datanucleus 6 will have Java 11 at least.
