I feel I missed something obvious, but I can’t google for anything useful, so please guys, help me out here 
The tutorial at https://docs.gradle.org/current/userguide/signing_plugin.html states that you should reference your secring.gpg file to sign your jars. However, this file is deprecated and no longer created by the gnupg tool. I am unable to create that file.
I have created a bug report at https://github.com/alkemist/gradle-signing-plugin/issues/2, but I fear that project is not managed actively.
Is there any way to force gnupg to create that secring.gpg file? Thank you!
