Support for changing Gradle dependency versions in TOML files

[michaelmcfadyensky]

What problem are you trying to solve?

We specify all of our dependencies and their versions inside toml files for our gradle projects. We would like a away to automate the upgrading of these versions via open rewrite.

Describe the solution you'd like

Recipe available for changing the version of a dependency specified in a toml file

Have you considered any alternatives or workarounds?

Consider using the find and replace recipe but it leads to several work arounds having to be in place for it to work.

Thanks for logging it as an issue! As indicated we do have a toml parser, but that'd need to be dusted off and cleaned up a bit before putting that to use. Likely to tie in with the recently added

• Add GradleDependency trait #4394

@steplica thanks a lot for the offer to help!

1. I think in the early stages of getting the parser to work @knutwannheden might be best to guide you, as he's been most active with recent parser developments. I'd expect rewrite-toml should still be part of openrewrite/rewrite, with an eye towards integration with Gradle
2. once the parser works we'd need to hook it into the rewrite-maven-plugin and rewrite-gradle-plugin, and rewrite-polyglot
3. then once files are parsed as Toml, we'd need to integrate with our Gradle support; at that point we can tag Shannon Pamperl (also here) for guidance, likely looking towards our Trait support to minimize recipe changes
