Hi,
I cannot test the plugin any more for the moment, i get this error :
Plugin ‘Diffblue Cover Community Edition - Unit Test Generator’ (version ‘2020.11.04-eval’) is not compatible with the current version of the IDE, because it requires build 202.* or older but the current build is IC-203.5981.155
Do i have to update my version of IntelliJ ? i don’t understand why it would have installed a wrong version of the plugin… 
And for your tip, i can tell you that i have already put my log4j2.xml file in the src/main/resources folder (i’ve tried src/test/resources also). I’ll test it again.
Thank you,
Frederic
