Everything works as expected, however on all > usages I would get the warning: > {noformat} > [WARN] The SLF4J binding actually used is not supported by Maven: > org.apache.logging.slf4j.Log4jLoggerFactory > [WARN] Maven supported bindings are: > [WARN] (from > jar:file:/opt/apache-maven-3.3.9/lib/maven-embedder-3.3.9.jar!/META-INF/maven/slf4j-configuration.properties) > - ch.qos.logback.classic.LoggerContext > - org.slf4j.helpers.Log4jLoggerFactory > - org.slf4j.impl.SimpleLoggerFactory > {noformat} > This looks pretty harmless, and I was able to suppress it by manually adding > the line > {code} > org.apache.logging.slf4j.Log4jLoggerFactory > org.apache.maven.cli.logging.impl.Log4j2Configuration > {code} > to {{/META-INF/maven/slf4j-configuration.properties}} in > {{maven-embedder-3.3.9.jar}}. > I'm not sure that this is a "correct" solution, and I'm not even confident I > could explain what effect it has, hence not posting a patch, but somebody > with more knowledge might be able to triage this better. Or offer an > "official" way to do colorized output. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
