This is the compilation of a clean QtQuick project.
I already set JAVA_HOME to correct path:

but continue to have this error:

> Android Gradle plugin requires Java 11 to run. You are currently using Java 1.8.
  Your current JDK is located in  /usr/lib/jvm/java-8-openjdk-amd64/jre

I suspect that there is another place to change this path, but I don't where go to see.
Can you help me?
Thanks.

@JoeCFD Hi and thanks for your help.
As I already wrote, I've already installed Java 11 and changed JAVA_HOME path in Qt environment, but I cotinue to have this error and I don't know where I can change configuration for Gradle.

JoeCFD

sorry I did not see it. It must be some path issue. Can you purge java 1.8 in /usr/lib/jvm/java-8-openjdk-amd64?
also try to add:

set(JAVA_HOME $ENV{JAVA_HOME})

in your cmake file

@Stefanoxjx Did you try https://computingforgeeks.com/how-to-set-default-java-version-on-ubuntu-debian/ ?

@jsulm Hi, yes, this is first thing that I did.
Now I purged 1.8 version too, as reccomended by joeCFD, but at the moment I've another compilation problem and I have to fix this first.

Stefanoxjx

I solved the compilation problem and with purge of old java version all works fine :)
Thanks a lot at all for help :)
