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.

Tpl warning.png

Use o oracle java 8 ou o Open Java 8.
