You can use following maven commands to run your application. #Run Java Program

mvn exec:java -Dexec.mainClass="com.jhh.Main"  
mvn exec:java -Dexec.mainClass="akka.Main" -Dexec.args="com.jhh.HelloWorld" 

#Run Scala Program

scala -Dlog4j.configuration=conf/template-log4j.properties target/java_abstract-1.0-jar-with-dependencies.jar conf/template-application.conf
mvn scala:run -DmainClass=com.jhh.App -DaddArgs="arg1|arg2|arg3"

#Assembly all project into a single jar file

mvn clean compile assembly:single

or

mvn clean compile package

After the above command, there are two jar files would be generated:

1. a jar file with all depandent packages
2. a single jar file only containing the project source code

#Change main and premain class file in pom file You need to revise the pom file to specify a new main/premain class entry if you want to a new one in your code. The default value is "org.ucf.ml.ScalaApp"

There are two properties in the pom file

1. project.main.class: Set the main entry of all project
2. project.main.class: Set the premain entry of Java instrumenttion

Execute jar file

java -cp {all needed depandency package } -jar {the target jar file} 

For example

$ pwd
/Users/Bing/Documents/workspace/test
$ ls
README.MD	pom.xml		src		target		test.iml
$ java -jar target/test-1.0-SNAPSHOT-jar-with-dependencies.jar 
Hello World from Scala

In the pom file, "{package}.ScalaApp" is set as the main entry class of the project. If you want to switch to "{package}.JavaApp", you just modify pom file
