[jira] [Commented] (WICKET-6955) Wicket uses unstable slf4j version

["Thomas Kamps (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-6955?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17486309#comment-17486309 ] 

Thomas Kamps commented on WICKET-6955:
--------------------------------------

We restricted the slf4j verison as follows
{code}
        api("org.slf4j:slf4j-api") {
            version {
                strictly("1.7.35")
            }
            because("We have no compatible log4j implementation for slf4j-2.0.0-alpha5")
        }
 {code}
We need this constraint, because othwise the slf4j2 version does not find a usable logger implementation and therefore no logs are printet out.
With it Gradle is not able to reolve a slf4j version that satisfies the dependencies constraints.

>             Project: Wicket
>          Issue Type: Bug
>    Affects Versions: 9.5.0, 9.6.0, 9.7.0
>            Reporter: Thomas Kamps
>            Priority: Major
>
> Since Wicket 9.5.0 the dependency of slf4j has changed from 1.7.25 to 2.0.0-alpha2 or some later alpha versions.
> This change  keeps us from upgrading to those versions, since there is currently no compatible Log4j implementation for slf4j 2.0.0-alpha (Which i can understand, because it is an alpha version, which can change its api rapidly).
> We tried to enforce using an 1.7 version, but that did not work because of some other libs that use slf4j in a 1.7 version.
>  
> So please change the used the slf4j back to an relased 1.7 version.
