Jak zainstalować Groovy?

Kiedy próbuję uruchomić to:

sudo apt-get install groovy 

Otrzymuję ten duży błąd:

Mam już zainstalowaną Javę na moim komputerze. Kiedy biegnę:

java -version

Dostaję :

java version "1.7.0_04"
Java(TM) SE Runtime Environment (build 1.7.0_04-b20)
Java HotSpot(TM) Server VM (build 23.0-b21, mixed mode)

gdzie popełniam błąd?

Z góry dziękuję.

Odzyskałem po tym błędzie, wykonując:

sudo apt-get purge openjdk*

Spowoduje to monit o usunięcie tych openjdk, które zostały zainstalowane w systemie. Kontynuuj z tym. Po openjdkusunięciu z komputera możesz:

sudo apt-add-repository ppa:groovy-dev/groovy
sudo apt-get update
sudo apt-get install groovy

Spowoduje to zainstalowanie stabilnej wersji. Następnie zrób to w swoim terminalu:

groovy -version

To powinno dać ci wynik:

Groovy Version: 1.8.6 JVM: 1.6.0_24 Vendor: Sun Microsystems Inc. OS: Linux

Zamiast tego po prostu zainstalowałem GVM (Groovy enVironment Manager) i użyłem go do zainstalowania Groovy .
