[jira] [Commented] (LOG4J2-346) Cyclic dependency in OSGi-context.
Apache Log4j SLF4J Binding <-> slf4j-api
[ https://issues.apache.org/jira/browse/LOG4J2-346?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13917621#comment-13917621 ]
Matt Sicker commented on LOG4J2-346:
------------------------------------
Shouldn't the module names match the artefact names in some way? Like for instance, log4j-core-osgi-jpa should be in a directory called log4j-core-osgi-jpa. I'm not positive on that, but it seems to be common Maven practice to do so. At least that's what I could grok from the maven site plugin bug MSITE-695 mentioned in the root pom.
Also, I'd prefer to use the name "bundle" over "osgi". I would think that including "osgi" in the name indicates specific OSGi framework things like implementations of core or compendium OSGi services, etc. Then you'd get a name like log4j-bundle-core-jpa which kind of looks weird. I'd prefer log4j-core-jpa-bundle. This way, all the normal JARs have corresponding *-bundle JARs as well.

> The bundle "Apache Log4j SLF4J Binding" (2.0.0.beta8) has an unresolved dependency to the package org.slf4j which is exported by the slf4j-api bundle. The Slf4j-api bundle has also an unresolved dependency to the package org.slf4j.impl which is exported by the bundle "Apache Log4j SLF4J Binding". Without the slf4j-api everything works. But the Slf4j-api bundle is needed because of given dependencies of third-party-bundles. The "Apache Log4j SLF4J Binding" bundle should also export the package org.slf4j.
