Update Archetype 24 to Support Eclipse

Customer is currently stuck using Archetype 20 but is running into issues with JSP support and is unable to upgrade to archetype 21,22,23 due to a previous FileNotFound Issue (https://github.com/adobe/aem-project-archetype/issues/358). The solution was to upgrade to Archetype 24 but are unable to do so since Eclipse is not supported. Looking to find out the timeline for this support and push for the update of Archetype 24 to support the use case.

Start by reviewing the Archetype 24 project and the previous FileNotFound issue #358 to understand the Eclipse compatibility gap. The issue names no files or tests, so first identify where Archetype 24 defines or limits Eclipse support. Done means the reported Eclipse use case works with Archetype 24 and is covered by appropriate validation.
