Gerar pacote JAR para desktop
No Linux, na pasta do projeto executar:
./gradlew desktop:dist
No Windows, na pasta do projeto executar:
gradlew desktop:dist
Vai ser gerado um jar na pasta desktop/build/libs/ . Copie o arquivo ou execute lá:
java -jar desktop-1.0.jar
Você pode renomear o arquivo para o nome do projeto.
