How to build Maven Repository

1. Download nexus war file from http://www.sonatype.org/downloads/nexus-2.1.2.war
2. Rename nexus-2.1.2.war to nexus.war. 
3. Put nexus.war into your tomcat webapp folder. 
4. Start tomcat server 
5. Login your nexus server:  http://127.0.0.1:8080/nexus (the default user/password: admin/admin123)
6. Use the web UI to upload your jar file, as follows: 

• Select the "3rd party" repository
• Choose the "Artifact Upload" tab. 

• Follow the steps in the screen to choose your jar file to upload. 

• Choose the "Browse Storage" tab to check your uploaded jar file
• Double click your uploaded jar file (i.e, Test-1.jar) will show the dependency content for pom.xml

In you pom.xml, you need to add the following content to connect your maven repository: 

• <repositories>
• <repository>
• <id>VPDC</id>
• <name>VPDC Repository</name>
• <url>http://localhost:8080/nexus/content/groups/public/</url>
• </repository>
• </repositories>

To get your uploaded jar file (i.e., Test.jar), you also need to add the following content in your pom.xml: 

• <dependency>
• <groupId>org.springframework</groupId>
• <artifactId>spring-hibernate3</artifactId>
• <version>2.0.8</version>
• </dependency>
