How to get the next build number in Gradle

Question

Is there any way to get the next version when publishing to a repository in gradle?

For e.g. if I have the version 3.0.1 in my repository I want the published version to be 3.0.2.

ivy has a task for ant named buildnumber which does exactly that:

<project xmlns:ivy="antlib:org.apache.ivy.ant"      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">  <target name="ivyBuildNumber" description="Use ivy get the next build number">     <ivy:buildnumber         resolver="url-chain"         organisation="${ivy.organisation}"         module="${ivy.module}"         revision="${version.base}"/>      <echoproperties prefix="ivy.new."/> </target> 

Is there a way to do so in gradle? if not how can I access ivy tasks from gradle's ant?

In my build.gradle I calling to the ant

ant.importBuild 'build.xml' 

Answer 1

I don't think there is support in Gradle, but you can try to use the Ant task. https://docs.gradle.org/current/userguide/ant.html#sec:import_ant_build

Another way to do this is to use some sort of plugin, or customized task for managing the version.

• Plugin: https://github.com/researchgate/gradle-release
• Custom task: https://www.tikalk.com/devops/increment-version-numbers-in-gradle/

Yes, you can access ivy tasks from the ant script by importing ant's build.xml file to gradle's build.gradle file. Following is the syntax to do so.

ant.importBuild 'build.xml'
