1. Add the sonatype-nexus-staging entry to the <servers> list in your maven settings file ($HOME/.m2/settings.xml). Replace username and password with your Sonatype username and password.

<!-- sonatype-nexus-staging -->
<server>
  <id>sonatype-nexus-staging</id>
  <username>username</username>
  <password>mypassword</password>
</server>

We recommend encrypting your maven passwords. See the maven password encryption guide for advice on how to encrypt your maven passwords.

1. Create a Sonatype account and request to be added to the list of users with deployment permissions.

2. Create a GPG key and publish it.

• Generate the key (brew install gpg2 to get gpg2 on a Mac)

  gpg2 --gen-key

  Use the default values for type, size, expiration, and add your name and email.

• List the key and note the key id

  gpg2 --list-keys

  The output should look similar to the following, where ABCDEF12 is your key id.

  --------------------------------
  pub   4096R/ABCDEF12 2015-02-04
  uid       [ultimate] John Doe <[email protected]>
  ...
  

• Upload your key to a key-server

  Use the following command, replacing ABCDEF12 with your own key id.

  # use the key id as shown by gpg2 --list-keys
  gpg2 --keyserver hkp://pool.sks-keyservers.net --send-keys ABCDEF12

# Make sure gpg-agent is running
eval $(gpg-agent --daemon)

# Prepare a release for the parent pom
mvn release:clean release:prepare

# Perform the release
mvn release:perform

# once staging is complete promote the release
cd target/checkout && mvn -Prelease nexus-staging:release
