Using PGP keys in GitHub secrets with the nexus-publish-plugin

[thunderbiscuit]

You run into problems if you paste an entire private key as it comes out in ascii-armor format on your command line. I think this is because the GitHub secrets is added as a string, and the spaces create multiple strings instead of one.

In the end, the way to make it work is to add the following in the secrets:

1. The PGP key passphrase, no quotes
2. The secret key as a single, long string, no quotes, formatted as per the docs
3. The key ID (the last 8 characters of the key fingerprint), no quotes
