Hi everyone, Someone can help me?, I'm trying to generate the .jar with intellij and maven, using artifacts, but when I double click on the generated file nothing happens. The program only works when run from intellij

Running a jar directly depends on your opearting system. Under Linux, it needs to be executable and binfmt has to be setup. I think under Ubuntu (and other Debian based systems) the package neede for that is

binfmt-support

thanks, but im on windows and i can open others .jar. Only this is not working and i dont know why

[Draget]

Ah okay. Then it is probably missing a Manifest or the Manifest does not specify the main class.

When packaging using the manven-jar-plugin you can add a configuration to set the main class.

IDEA (or other IDEs) know the main class by looking through the code and generting a run-configuration (IDE-specific) but regular java always wants to have the main class specified that should run (and this can be done via the Manifest which is added by that maven-jar-plugin)
