Custom rewrite appender not working when used like dependency on spring boot app

[NikolaSrica]

so I have a spring boot project that have his own log4j2.xml file inside resources and all is working fine ... i have the second project with the same setup but here I have a custom rewrite appender that is working fine when running that project. The problem appears when in the project A I have a dependency on project B and then the log4j2.xml is not loading correctly rewrite appender . What I need to add to log4j2.xml file so he can use the custom appender from imported project ?

Project A has a dependency on Project B, which contains a custom appender, that you want to use in the log4j2.xml of Project A, right?

1. How do you package Project B? Is it just a regular library JAR?
2. How do you import Project B into Project A? As a regular Maven/Gradle dependency?
3. You've read Extending appenders and using the PluginProcessor annotation processor while building the Project B, right?
