Ganttproject ne se lance pas

Stormtrooper

Bonjour à toutes et tous,

J'ai installé la dernière version de Ganttproject sur mon PC qui est sous MATE 18.04.

Le paquet est bien installé mais en cliquant sur le lanceur, l'icône apparaît dans le dock quelques secondes, puis, disparaît et rien ne se passe.

J'ai tenté de le lancer en ligne de commande, en tapant dans un terminal

ganttproject

J'obtiens un long message d'erreur auquel je ne comprends rien du tout; hormis qu'il est question de Java:

Installe une version plus ancienne de java :

sudo apt install openjdk-8-jre

Ensuite, comme tu auras une version 8 et la version 10 installées, il faut indiquer au système quelle version de JRE utiliser :

sudo update-alternatives --config java

Ceci va lister la liste des versions disponibles, et tu n'auras plus qu'à choisir le numéro de celle que tu souhaites utiliser par défaut. Dans ton cas, la 8.

Stormtrooper

Ça fonctionne parfaitement.

Merci inbox! 😃

Je passe le sujet en résolu.
