XIAOMING ZHAO created LOG4J2-3519:
-------------------------------------
Summary: Log4j2 failed to load custom plugin
Key: LOG4J2-3519
URL: https://issues.apache.org/jira/browse/LOG4J2-3519
Project: Log4j 2
Issue Type: Bug
Components: Plugins
Affects Versions: 2.17.1
Reporter: XIAOMING ZHAO
We got some issue to load the custom plugin.
we add annotation Plugin like the following:
@Plugin(name = "UnifiedLoggingFormat", category = Node.CATEGORY,
elementType = Layout.ELEMENT_TYPE, printObject = true)
public class UnifiedLoggingFormat extends AbstractStringLayout
then add the annotationProcessor in build.gradle
annotationProcessor( 'org.apache.logging.log4j:log4j-core:2.17.1')
after the build, we can see the META-INF/org/apache/logging/log4j/core/config/plugins/Log4j2Plugins.dat in the class jar file.

then in log42j.xml, we added the package of this custom plugin class.
<Configuration status="trace" monitorInterval="30" packages="com.server.logging.log4jappenders, com.common.utils">
but we still got the problem

FelixDispatchQueue DEBUG Took 0.000117 seconds to load 0 plugins from package com.common.utils
