Estoy tratando de instalar esto desde git .
(Estoy ejecutando Ubuntu.) Recibo este error

De hecho, necesitaba actualizar JDK a JDK 8. Esto es lo que utilicé:
$ sudo add-apt-repository ppa: webupd8team / java
$ sudo apt-get update
$ sudo apt-get install oracle-java8-installer
Una vez que se instaló, también necesité agregar sudo antes de mvn clean package install
Funcionó a las mil maravillas. Gracias a @Jesper
