[jira] [Comment Edited] (LOG4J2-673) plugin preloading fails in
shaded jar files
[ https://issues.apache.org/jira/browse/LOG4J2-673?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14595939#comment-14595939 ]

Hi,
I have the same problem when creating a jar with dependencies in maven.
I am looking how I can merge manually the dat files to overwrite them in the assembly by including it.
Is some guide available how you can merge those files or how the files need to be interpreted please?
Kind Regards
Günther

> Project: Log4j 2
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0-rc2, 2.1
> Reporter: mck
> Assignee: Matt Sicker
> Priority: Critical
> Labels: annotations, compiler, plugins
> Attachments: 0002-LOG4J2-673-plugin-preloading-fails-in-shaded-jar-fil.patch, 0005-LOG4J2-673-plugin-preloading-fails-in-shaded-jar-fil.patch

> Support for plugin preloading through the standard javax.annotation.processing tool was adding in LOG4J2-595
> But the plugin processor always creates and stores the processed "Plugin" annotated classes into the same file. This works fine when the classpath consists of individual jar files, but fails when shaded jar files are used.
> A tested fix exists at https://github.com/finn-no/logging-log4j2/tree/bugfix/LOG4J2-673
> There's also a github pull request and a manual diff attached. (I can clean up anything not used afterwards)
> The fix saves the dat file in a location under META-INF that matches the shared package all the processed plugins are found under.
> The package attribute in the config file is then used so that multiple dat files can be loaded at runtime.
> This means that the package attribute is no longer deprecated.
> This has been tested against https://github.com/finn-no/log4j2-logstash-jsonevent-layout
