Sakai 20.x Deploy failure in sakai-portal-api

Question

System:

• Ubuntu 20.04
• Java version: 11.0.9.1
• Apache Maven 3.6.3
• Tomcat 9

deploy process stops after sakai-portal-api (without error text)

sudo mvn clean install sakai:deploy -Dmaven.tomcat.home=/usr/share/tomcat9 -Dsakai.home=/usr/share/tomcat9/sakai -Djava.net.preferIPv4Stack=true

I've tested with maven option "-Dmaven.test.skip=true" too, but same error

I also tested with the stable version "git checkout 20.0" (instead of 20.x), but then it stops at "Sakai Component Manager"

Any idea, what I can do?

Answer 1

you can't use java 8 because sakai 9 recommend it
