为什么我的JAVA_HOME指向jre而不是jdk？

Question

I want to compile a project on my manjaro system using mvn and every time I get this error:

The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK, not a JRE

Can somebody help?

Answer 1

Found the Solution myself:

sudo archlinux-java set <target java package name>

For Example:

sudo archlinux-java set java-15-jdk
