I just tried the transformer and I still get "ERROR StatusLogger Unrecognized
conversion specifier..."
{code:xml}
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.4.3</version>
<configuration>
<transformers>
<transformer
implementation="com.github.edwgiz.mavenShadePlugin.log4j2CacheTransformer.PluginsCacheFileTransformer"
/>
</transformers>

<dependency>
<groupId>com.github.edwgiz</groupId>
<artifactId>maven-shade-plugin.log4j2-cachefile-transformer</artifactId>
<version>2.1</version>
</dependency>
</dependencies>
</plugin>
{code}
Is this still supposed to work?
It looks like the code is hardwired to Log4j 2.1 and I am using 2.6.1. What
will happen? A 2.1 dat file which won't work on 2.6.1?

> plugin preloading fails in shaded jar files
> -------------------------------------------
>
> Key: LOG4J2-673
> URL: https://issues.apache.org/jira/browse/LOG4J2-673
> 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
