For me  this was something as simple as a missing version for my artifact -  1 1-SNAPSHOT

I got the same message   repository element was not specified in the POM inside distributionManagement element    I checked  target checkout pom xml and as per another answer and it really lacked  lt distributionManagement gt    It turned out that the problem was that  lt distributionManagement gt  was missing in pom xml in my master branch  using git    After cleaning up  mvn release rollback  mvn clean  mvn release clean  git tag -d v1 0 0  I run mvn release again and it worked

The ID of the two repos are both localSnap  that s probably not what you want and it might confuse Maven   If that s not it  There might be more repository elements in your POM  Search the output of mvn help effective-pom for repository to make sure the number and place of them is what you expect

You can also override the deployment repository on the command line  -Darguments -DaltDeploymentRepository myreposid  default  http   my url releases

Review the pom xml file inside of target checkout    Chances are  the pom xml in your trunk or master branch does not have the distributionManagement tag
