Description

I am posting this issue on behalf of the official Jakarta EE Starter project at the Eclipse Foundation: https://start.jakarta.ee. We make use of Maven Archetypes in the Starter under the hood and also as an API: https://github.com/eclipse-ee4j/starter/tree/master/archetype.

We are pretty dependent on Groovy and use groovy.text.SimpleTemplateEngine for some critical functionality: https://github.com/eclipse-ee4j/starter/blob/ca9b5028b7fe3b47ecf4b5e5c22e89bc941e99a0/archetype/src/main/resources/META-INF/archetype-post-generate.groovy#L144.

A few days ago we noticed that the Archetype is suddenly broken with the following error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:3.3.0:generate (default-cli) on project standalone-pom: startup failed:
[ERROR] Script1.groovy: 144: unable to resolve class groovy.text.SimpleTemplateEngine
[ERROR]  @ line 144, column 18.
[ERROR]        def engine = new groovy.text.SimpleTemplateEngine()
[ERROR]                     ^
[ERROR]
[ERROR] 1 error

This seems to coincide with the 3.3.0 release of maven-archetype-plugin. Any idea what is going on and how to fix this?

Please LMK if you need anything from us?
