Logback to log4j2 support

[Misha123456]

I was reading the documentation here and can see log4j2 to logback conversion is supported.
But there is no way to convert vice versa (from logback to log4j2).

Are there plans to implement this in the future?

hi @Misha123456 ! We had not planned to support a migration from logback to log4j2, but are open to contributions in case you're interested to pick that up. Implementation wise I imagine it will be very similar to the log4j2 -> logback recipes. If you're merely looking to switch dependencies you could have a look at META-INF/rewrite/logback.yml, but a full migration might also involve converting for instance logback.xml.

@timtebeek,

Could you assign this issue to me?

I would split it into two independent recipes:

• "SLF4J to Log4j API", which mostly what library developers are interested in,
• "Logback to Log4j Core", which would be targeted to application developers and just switches dependencies and configuration.

Sure sounds good; Thanks for taking this on!
