mvn release:perform -Dmirage2.on=true
# NOTE: for DSpace 5.x, the LNI module must be manually specified (-Pdspace-lni) to ensure it is also released

You should be prompted by Maven to specify your GPG passphrase (which you established when you created your Code Signing Key). If you run into any issues, it's possible to specify your GPG key and passphrase as arguments to the above command (e.g. -Darguments="-Dgpg.keyname=YourKeyId -Dgpg.passphrase=YourKeyPassword")

1. Login to http://oss.sonatype.org/
2. Click "Staging Repositories" in the left column, then select the checkbox next to the staged repository on the right. The contents of it will open up at the bottom of the page.
3. With the staged repository still selected, click the "Close" button at the top.

4. Download and test that the artifacts in staging are exactly as they should be once deployed to central.

   Info
   title If You Need to Revert Back before Releasing
   If anything is incorrect, select the staged repository and select "Drop". After the problem is resolved, you can re-deploy the artifacts to staging and verify them again. To re-deploy an already-tagged release: mvn release:perform -Dmirage2.on=true -Dtag=dspace-x.y -DconnectionUrl=scm:git:git@github.com:DSpace/DSpace.git -Darguments="-Dgpg.keyname=YourKeyId -Dgpg.passphrase=YourKeyPassword"

5. If everything looks good, select the repository and select "Release". The artifacts should be synced to Maven central (http://repo2.maven.org/maven2/org/dspace/) within 2 hours.

   Warning
   title Once Released, There is No "Undo" Option
   Once you select "Release", there is no way to "undo" the release. If any major issues are found, you'll have to increment the version number and perform a new bug-fix release.

Create the Distribution Zips

...

The previous actions will have checked out the release tag into the target directory under [dspace-src]/target/checkout/dspace/. Navigate to that directory and execute the creation of the distributions using the following command. This will create two zip, bzip and gzipped files in the target directory. One set of files is the "binary" release, and the other set is the source release.
