Somehow Step 3. Configure your system environment part of the Installation page does not fully agree with 3.4. Environment variables part of The Gradle User Manual/Guide: the later says one should set
GRADLE_HOME, while the former doesn’t even mention such an environment variable.
GRADLE_HOME some kind of legacy thing that is no longer needed?
Can you please hint on what are the likely outcomes of it (not) being set?
p.s. Another minor inconsistency is that the User Guide is called “User Manual” on the Documentation page, but seems to be referred to as “User Guide” everywhere else.
