If you really don't want to use the Maven Release Plugin (for whatever reason), here is how I succeed on dropping the SNAPSHOT suffix (hanbdled as a classifier) from a maven POM in a standard way (that is, no scripting, no custom maven plugin).

Given the following profile:

    drop-snapshot
    
        
            
                org.codehaus.mojo
                build-helper-maven-plugin
                1.11
                
                    
                        parse-version
                        validate
                        
                            parse-version
                        
                    
                
            
            
                org.codehaus.mojo
                versions-maven-plugin
                2.2
                
                    
                        set-version
                        validate
                        
                            set
                        
                        
                            ${parsedVersion.majorVersion}.${parsedVersion.minorVersion}.${parsedVersion.incrementalVersion}
                        
                    
                    
                        upgrade-pom
                        validate
                        
                            commit
                        
                    
                
            
        
    

And simply executing: mvn validate -Pdrop-snapshot
The version of an example pom passed from 0.0.1-SNAPSHOT to 0.0.1.

How it actually works:

• The build-helper-maven-plugin, parse-version goal, will parse the current version of the POM and set it in a set of properties having by default parsedVersion as a prefix and majorVersion, minorVersion, incrementalVersion as suffixes (check the documentation, you will also have classifier and buildNumber). Hence, after its execution we can then use in our POM the properties like ${parsedVersion.majorVersion} and so on.
• The versions-maven-plugin, set goal, will then use these properties to build the new version you actually want (in this case dropping the SNAPSHOT, because we excluded the ${parsedVersion.classifier} property).
• Lastly, the versions-maven-plugin, commit goal, will make these changes effective.
