Maven artifactId should have lowercase letters. Guide to naming conventions says:
artifactId is the name of the jar without version. If you created it then you can choose whatever name you want with lowercase letters and no strange symbols.
Has Gradle something similar? How should Gradle projects be named?
By default if a Gradle project produces an archive, like a jar, the archiveName will be derived from the project name.
However this is something you can customise if you want, see documentation.
Note that if you do not name your project, in the settings.gradle, the project name will default to the folder containing it.
And finally, if what you build is to be consumed by others, then I recommend sticking with the artifactId conventions.
