build: remove logback.xml from release jar

[theborakompanioni]

The current jar includes a logback configuration file.

If a downstream consumer also defines a logback.xml, logback will complain about it on stdout, which makes cln killing the plugin. This happens even with <root level="OFF"> and no console appender defined.

11:19:14,443 |-INFO in LoggerContext[default] - Found resource [logback.xml] at [file:/home/user/workspace/tapplication/build/resources/main/logback.xml]
11:19:14,443 |-WARN in LoggerContext[default] - Resource [logback.xml] occurs multiple times on the classpath.

Logback only outputs its status messages when there is a warning or error - in this case Logback thinks that you have two logback.xml files on the classpath.

An additional side effect is that a clightning4j dir is created in the users home directory.
Would it be possible to exclude the logback.xml file in the release builds?

I guess yes, but I need to see how I can do it with the current grade plugin, I guess this is the code that should include the fix https://github.com/clightning4j/JRPClightning/blob/master/gradle/release.gradle#L19

I guess one can just include something like the following lines to the jar task in build.gradle:

    jar {
        exclude('logback.xml')
    }

But let's first consider whether it really makes sense or if some other approach is better suited. ; -)
