Generate Build Number Maven

Generate Build Number Maven

While working with maven project and if you are using any SCM as repository which is mandatory in any company then it’s required to generate build number dynamically when build new jar of the project. As this is very simple by using org.codehaus.mojo plugin in your maven pom.xml. I will be creating sample project where I am using git as reposiroty and javahonk Git is public repository you can use it without any issue. Sample maven project structure:

• You could download this project form Git here
• Please add below to your maven pom.xml file:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>com.javahonk</groupId>
	<artifactId>GenerateMavenBuildNumber</artifactId>
	<version>${version}</version>
	<name>GenerateMavenBuildNumber</name>

	<properties>
		<version>1.0</version>
	</properties>

	<build>
		<finalName>${project.artifactId}-${project.version}_${buildNumber}</finalName>
		<plugins>
			<plugin>
				<groupId>org.codehaus.mojo</groupId>
				<artifactId>buildnumber-maven-plugin</artifactId>
				<version>1.1</version>
				<executions>
					<execution>

				</executions>
				<configuration>
					<doCheck>false</doCheck>
					<doUpdate>false</doUpdate>
					<revisionOnScmFailure>true</revisionOnScmFailure>
					<format>{0,date,yyyy-MM-dd_HH-mm}_{1}</format>
					<items>
						<item>timestamp</item>
						<item>${user.name}</item>
					</items>
				</configuration>
			</plugin>
		</plugins>
	</build>

	<scm>
		<connection>scm:git:git://github.com/javahonk/GenerateMavenBuildNumber.git</connection>
	</scm>

</project>
