Move org.openrewrite.java.apache.httpclient4.MigrateDefaultHttpClient to rewrite-apache

[JLLeitschuh]

What problem are you trying to solve?

org.openrewrite.java.apache.httpclient4.MigrateDefaultHttpClient seems to be in the wrong place as it isn't related to Spring.

Describe the solution you'd like

It would make sense to move the org.openrewrite.java.apache.httpclient4.MigrateDefaultHttpClient to a dedicated rewrite-apache package.

Hi! Yes I think you're right; We started out here as it's a requirement for the Spring migration, but by no means exclusive to it. We've similarly split off rewrite-hibernate and rewrite-openapi in the past, and this feels like a natural extension to that. We could then also move the Apache commons recipes that are now in rewrite-migrate-java into rewrite-apache.

I've gone ahead and created https://github.com/openrewrite/rewrite-apache ; Now all I need is a bit of time to wrestle with Git to keep authorship of the original files when moved into there, such that the docs will show all involved.

Completed this migration using this reference, and moving the paths to match the new target location.

Still to do:

• do an initial release and include with rewrite-recipe-bom & release bot
• update rewrite-docs and rewrite-recipe-markdown-generator
• remove references from rewrite-spring and rewrite-migrate-java
• run weekly internal vulnerability scans against rewrite-apache
• deploy to app.moderne.io & possibly others
• add quick regex recipe for folks that want to adopt the new recipe paths
