java-publish

This action publishes maven artifacts.

Publication

Username and password are not required when publishing to GitHub Packages. (https://maven.pkg.github.com/<your_username>/<your_repository>)

Signing

To sign the artifacts, MAVEN_GPG_SIGN_PRIVATEKEY and MAVEN_GPG_SIGN_PASSWORD must be set. You can generate a private key using the gpg command line tools:

gpg --full-generate-key
// When asked for the key type, select `RSA (sign only)`.
// For the key size, select `4096`.
// For the expiration date, select `0` to make the key never expire.
// The Key-ID will appear in the output, it will look something like this `A1B2C3D4E5F6G7H8`.
// Use a strong password to protect the key, store it in the `MAVEN_GPG_SIGN_PASSWORD` secret.
gpg --armor --export-secret-keys A1B2C3D4E5F6G7H8 | base64 -w0
// Now store the secret key in the `MAVEN_GPG_SIGN_PRIVATEKEY`
