How to release an update to Maven Central

I have used following two guides, go there in case of problems:
Sonatype OSS Maven Repository Usage Guide
Publish an aar file to Maven Central with Gradle
I have already added most of the required configurations to the project, but you need some setup on your machine. Particularly:
latest Java, Git, Android SDK
GPG installed, public key distributed though their servers and path to the key and credentials in ~/.gradle/gradle.properties
add these properties: signing.keyId(short code visible for example in GPG Keychain Access on Mac), signing.password(password to GPG private key), signing.secretKeyRingFile(path to GPG file secring.gpg), nexusUsername(username to Sonatype), nexusPassword(password to Sonatype)
Sonatype account and permissions to the project in Sonatype.

Push & pull
setup target version in gradle.properties in project root
run gradle uploadArchives in project root
go to Staging repositories, select repository and click Close.
add this repo manually to some project and test the new version of the library
when everything is fine, let's do the final push. Go to Staging repositories and click Release
- artefacts will be in Maven Central in about 2 hours
Create release in GitHub Releases, it will create proper tag in git
