Using Maven Release Plug-In

You can use the Maven Release plug-in to package and release your Developer Studio projects. As a practice, at the development stage of the project, it is the SNAPSHOT version of the artifacts that is used. This is similar to the next major/minor version to be released. For example, if the next planned release version is 1.1.0, it is 1.1.0-SNAPSHOT that is used for versioning in the development stage.

Follow the steps below to deploy WSO2 artifacts to a nexus repository:

1. In the pom.xml file, configure the SCM configuration. For example,

    <scm>
       <connection>scm:svn:https://svn.wso2.com/wso2/interns/2013/vijithae/release/trunk</connection>
       <developerConnection>scm:svn:https://svn.wso2.com/wso2/interns/2013/vijithae/release/trunk</developerConnection>
       <url>https://svn.wso2.com/wso2/interns/2013/vijithae/release/trunk</url>
     </scm>

2. Point to the nexus repository of the project. For example,

   <distributionManagement>
          <repository>
              <id>deployment</id>
              <name>Internal Releases</name>
              <url>http://localhost:8081/nexus/content/repositories/releases/</url>
          </repository>
          <snapshotRepository>
              <id>deployment</id>
              <name>Internal Snapshot Releases</name>
              <url>http://localhost:8081/nexus/content/repositories/snapshots/</url>
          </snapshotRepository>
      </distributionManagement>

3. Configure with the wso2-release-helper-plugin and tag base. For example,
   
   

   <plugin>
       <artifactId>maven-release-plugin</artifactId>
       <version>2.5</version>
       <configuration>
   	 <preparationGoals>               
             org.wso2.maven:wso2-release-helper-plugin:1.0.0-SNAPSHOT:prepare-release
          </preparationGoals>
          <completionGoals>
             org.wso2.maven:wso2-release-helper-plugin:1.0.0-SNAPSHOT:prepare-snapshots
          </completionGoals>
   <tagBase>https://svn.wso2.com/wso2/interns/2013/vijithae/release/tags</tagBase>
       </configuration>
   </plugin>

   Note that the wso2-release-pre-prepare-plugin is now deprecated since the plug-in only supported svn and provided no support for rollbacks, dryRun mode etc.  

4. Execute the mvn release:prepare command inside the Maven Multi Module project. Give appropriate values for release, development, and tag versions when prompted.
5. Execute the mvn release:perform command inside the Maven Multi Module project.
