Sorry but I'm not sure to follow you.
Let's take my guava example on master.
In the gradle.properties, I see: guavaVersion=30.0-jre
In the WEB-INF/lib directory of the cas-server-webapp WAR, I see:
guava-2.9.0.jar
guava-30.0-jre.jar
guava-30.1.1-jre.jar
jackson-datatype-guava-2.12.3.jar
listenablefuture-9999.0-empty-to-avoid-conflict-with-guava.jar
What should I do? Update the gradle.properties file to version 30.1.1-jre for guava or search from which CAS dependency this version 30.1.1-jre comes from and exclude it in the dependencies.gradle file?
Thanks.
Best regards,
Jérôme
