Hey folks,

I’m building an open source java library and want to use deployment to upload compiled JAR files to Sonatype’s Nexus / Maven Central.

A big requirement they have is that I sign the build with a GPG key. I have the GPG credentials but am unsure about how to deploy and use them in a Circle CI build.

Could someone advise?

Thanks,

Matthew
