How to install your project into Maven local repository

In Maven, you can use “mvn install” to package your project and deploy to local repository automatically, so that other developers can use it.

mvn install

mvn install example

A Java project, with following pom.xml file

File : pom.xml

<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/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.mkyong.core</groupId>
  <artifactId>mkyong-core</artifactId>
  <packaging>jar</packaging>
  <version>99</version>
  <name>mkyong-core</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.4</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
</project>

Based on above pom.xml file, when “mvn install” is executed, it will package the project into “mkyong-core-99.jar” file and copy to your local repository. See following diagram :

mvn clean install

Access Deployed Project

Now, other developers are able to access your deployed “jar” file by declaring below dependency tag in their pom.xml file.

<dependency>
      <groupId>com.mkyong.core</groupId>
      <artifactId>mkyong-core</artifactId>
      <version>99</version>
 </dependency>
