Além disso, meu JAVA_HOME:

Como as dicas de mensagem de erro, você não tem um Java Development Kit (JDK) instalado, apenas um Java Runtime Environment. Um JDK é um superconjunto de um JRE e inclui ferramentas para desenvolver programas Java, ferramentas como o compilador Javac Java, que o plugin Maven precisa. Para corrigir, instale um JDK.
Eu instalei tools.jar e resolvi.
[root@server-1]# yum install java-1.8.0-openjdk-devel
