Situation with compiling a mission – JavaScript

Hello Buddies,

I get again to cocos2d-x after nearly half a decade. And having concern attempting to compile a brand new JS mission.

I’ve a contemporary Ubuntu 18.04 field setup with Java 1.8, Cmake, and all different dependencies as talked about @ https://docs.cocos.com/cocos2d-x/handbook/en/set up/Linux.html

Now once I create and run new mission with

cocos new -l js check
cd check
cocos run -p net

It really works flawlessly.

However when I attempt to compile with
cocos compile -p net -m launch
I get

Constructing mode: launch
No legitimate JDK discovered

I attempted including

JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64"
export PATH=$JAVA_HOME:$PATH

after which

JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64/jre"
export PATH=$JAVA_HOME:$PATH

after which

JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64/jre/bin"
export PATH=$JAVA_HOME:$PATH

With every of above settings, sourced .bashrc and tried operating
cocos compile -p net -m launch
solely to get

Constructing mode: launch
No legitimate JDK discovered

Any trace on what am I doing incorrect? Extremely recognize any responses.

Thanks.
