[jira] [Commented] (LOG4J2-1614) Package attribute for discovering custom plugins within jars fails

["Frank Conover (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LOG4J2-1614?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15527571#comment-15527571 ] 

Frank Conover commented on LOG4J2-1614:
---------------------------------------

Some test notes...

I am exporting a project as a jar from eclipse via right clicking the project and selected export. Even with annotation processing on, the Log4j2Plugins.dat file is not generated.

Next I compiled my project using with a script using javac and a Log4j2Plugins.dat file was created.

Just to verify the dat file option works. Using my original log4j2.xml file with the packages attribute still configured and trace on, I get the message that 0 appenders were found but my appender does get created. I took the packages attribute out and the 0 appenders line goes away and the appender is still created. So the dat file option is working for me.

> I am experiencing this issue with 2.6.3 and I tried 2.3. I have a custom plugin in a jar file. Works fine from eclipse, or a non-jar java app but not as a jar project. I have packages="... attribute filled out in my log4j2.xml. I added it to get the custom appender found while running from eclipse. As a non-maven program using jars which are on the classpath the appender is not found. Is there another way I should be doing this? Is packages still fixed / or still an available feature?
> Note: If I extract my jars and run, the appender is found.
> See: LOG4J2-741
> This referenced issue and the stack overflow link in the description of this issue sound like my issue. Do I need to compile with a certain flag turned on? Generate my jar a certain way?
