 https://docs.spring.io/spring-boot/docs/current/reference/html/getting-started-installing-spring-boot.html#getting-started-installing-the-cli

 Descargamos la ultima versión estable, la descomprimimos.


Creamos un lugar donde instalaremos los archivos

bext@bext-VPCF13WFX:~/Downloads$ sudo mkdir /opt/spring-boot

bext@bext-VPCF13WFX:~/Downloads$ sudo tar xzf spring-boot-cli-2.2.0.BUILD-20190708.150652-418-bin.tar.gz -C /opt/spring-boot
bext@bext-VPCF13WFX:~/Downloads$ ls /opt/spring-boot
spring-2.2.0.BUILD-SNAPSHOT

Editamos el archivo /etc/profile para agregarle

export SPRING_HOME=/opt/spring-boot/spring-2.2.0.BUILD-SNAPSHOT
export PATH=$SPRING_HOME/bin:$PATH

bext@bext-VPCF13WFX:~/Downloads$ sudo nano /etc/profile

 Actualizamos el cambio

bext@bext-VPCF13WFX:~/Downloads$ source /etc/profile

Probamos la instalación

bext@bext-VPCF13WFX:~/Downloads$ spring --version
Spring CLI v2.2.0.BUILD-SNAPSHOT

Creamos una sencillisima app web en Groovy para probar la instalación

bext@bext-VPCF13WFX:~$ nano app.groovy
bext@bext-VPCF13WFX:~$ cat app.groovy
@RestController
class ClaseAEjecutar {
 @RequestMapping("/")
 String home() {
  "Corriendo app en Groovy!!"
 }
}
bext@bext-VPCF13WFX:~$ spring run app.groovy
