Maven release: next development version in batch mode

Question

I have configured a Jenkins job to release my maven project automatically. This is done by using the following: mvn --batch-mode clean release:prepare release:perform

Answer 1

I had the same problem and I wanted to resolve it without running more than one command or by inserting the version manually.

Here is my solution for y (or minor) increment:

I run a Groovy script in initialize phase. This script creates release.properties. Add this to your project/build/plugins section in your pom.xml:

        
            org.codehaus.gmavenplus
            gmavenplus-plugin
            1.5
            
                
                    org.codehaus.groovy
                    groovy-all
                    2.4.6
                
            
            
                
                
                    release-parameters
                    initialize
                    
                        execute
                    
                    
                        
                            
                        
                    
                
            
        

This script changes also the tag name for vX.Y.Z in your SCM. The initialize phase is not executed in the release:prepare phase. To resolve this issue, you can run a "mvn install" before a release, or change your release command to:

mvn --batch-mode initialize clean release:prepare release:perform
