When I tried log4j2 backend [https://hagbard.github.io/the-flogger-manual/install/], I got below error. 
But when I use system backend it works

ApplicationTests > contextLoads() FAILED
    java.lang.IllegalStateException at DefaultCacheAwareContextLoaderDelegate.java:180

My current deps
//implementation 'com.google.flogger:flogger-log4j2-backend:0.8'
implementation 'com.google.flogger:flogger-system-backend:0.8'

thanks

I had to add below to force log4j2.  and added log4j2.xml. However, appenders are not working properly

configurations.all {
exclude group: 'ch.qos.logback', module: 'logback-classic'
 exclude group: 'ch.qos.logback', module: 'logback-core'
 exclude group: 'org.springframework.boot', module: 'spring-boot-starter-logging'
 exclude group: 'org.apache.logging.log4j', module: 'log4j-jul'
}

can someone pls advise if there is a simpler setup than this?

configurations.all {
exclude group: 'ch.qos.logback', module: 'logback-classic'
 exclude group: 'ch.qos.logback', module: 'logback-core'
 exclude group: 'org.springframework.boot', module: 'spring-boot-starter-logging'
 exclude group: 'org.apache.logging.log4j', module: 'log4j-jul'
}
implementation "org.springframework.boot:spring-boot-starter-log4j2"
implementation 'com.google.flogger:flogger:0.8'
implementation 'com.google.flogger:flogger-log4j2-backend:0.8'

thank you
