If i run java -version:

java version "11.0.3" 2019-04-16 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.3+12-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.3+12-LTS, mixed mode)

Answer 1

1. Open conf/wrapper.conf file
2. Change wrapper.java.command=java to path where your JavaDK is installed eg. wrapper.java.command=C:\Program Files\Java\jdk-11.0.4\bin\java

Answer 2

I had the same problem a few moments ago, my JAVA_HOME variable pointed to the correct version of my profile, but when I run java -version, it printed 1.8, so I run this command:

update-java-alternatives -l

This showed me all Java versions that were installed on my machine.
After that, I run this another command:

sudo update-java-alternatives -s java-11-oracle

This changed the Java version on my machine and it works just fine.
