Hi everyone,
I forked and cloned the project from GitHub
<https://github.com/apache/logging-log4j2>. And spent the past couple of
hours trying to build from source with mvn install.
It is failing with errors saying "class file has wrong version 55.0, should
be 53.0" for "bad class file: /modules/java.base/java/util/EnumSet.class",
which I think it means I probably need to find a Java 9 to install and
build the project with? But since Java 9 was discontinued, I haven't been
able to find an Oracle nor an OpenJDK version to install.
I have attached an output txt file for maven install and my current maven
toolchain.xml if it helps clarifying what I might have been doing wrong.
Thanks,
Joseph
