Sketch doesn't run on linux

Processing Beginners

Hi!

I recently installed processing version 3.5.4-6 on my laptop which has a linux manjaro OS.

First I couldn’t open the program at all, but I figured out that I needed to change the Java environment to java-8-openjdk/jre. Now the program opens, but when I try to run the code I get a bunch of errors that I don’t know how to solve.

example:

void setup(){
 size(300,300); 
}

void draw(){
  rect(100,100,50,50); 
}

Gives this of list of errors.

Any ideas what could be the problem?

I read error so that java was not found. I run processing on a Ubuntu laptop and installation has always been a breeze. After downloading and extracting files I just ran install.sh installation script and all just worked fine. Processing comes with compatible java, so the should be no need to change jre or set environment.
