Using the WebLogic 12c Maven Plug-In for Deployment

Using the WebLogic 12c 12.1.2 Maven plug-In for deployment is much easier and quicker than going through the WebLogic Server’s AdminServer and Oracle Documentation provides good examples how to do it. The weblogic-maven-plugin provides enhanced functionality to install, start and stop servers, create domains, execute WLST scripts, and compile and deploy applications.

The weblogic-maven-plugin plug-in is provided as a pre-built JAR file and accompanying pom file. In short, installing and configuring the WebLogic 12c Maven sync plug-in contains following steps:

Open command prompt and run commands:

cd D:\oracle\wls12120\oracle_common\plugins\maven\com\oracle\maven\oracle-maven-sync\12.1.2
mvn install:install-file -DpomFile=oracle-maven-sync.12.1.2.pom -Dfile=oracle-maven-sync.12.1.2.jar
mvn -Doracle-maven-sync.oracleHome=D:\oracle\wls12120

You can validate whether you have successfully installed the plug-in using the Maven help:describe goal.

mvn help:describe -DartifactId=weblogic-maven-plugin -Dversion=12.1.2-0-0

And you’re ready to deploy with Maven. A lot more easier than generating the WebLogic 11g R2 Maven Plug-in where you had to i.a. build the jar by yourself.

The Maven plug-in can be used e.g. from application’s POM file and be bound to some phase of the Maven life cycle. For example it can be bound to “install” phase and every time you run the “mvn install” command, the deployment plug-in is also called. In my opinion better way to use the plug-in is to add it as a profile so you can call it just when you want with command like “mvn clean install -Pdeploy-wls“.

Maven Project pom.xml File


The user credentials in the POM file are provided as clear-text but for more security you can use secure configuration authentication mechanism which stores the user name and password in encrypted form in an external file, and then uses it to supply the user credentials with which to connect to the WebLogic Server domain, along with the key that was used to encrypt the file.
