Maven Usage

Maven is used for compiling and managing dependencies.
The pom.xml file is the XML representation of the project and thus contains all metadata pertaining to the project.

$ mvn archetype:generate

you will have to enter the Maven "project co-ordinates" such as groupId, artifactId, version, and package.

groupId: com.companyname

artifactId: project name

version: 1.0-SNAPSHOT

packaging: jar

2. Compile a project. Navigate to pom.xml folder.

$ mvn compile

It will download dependencies, then It will trigger the Java compiler associated with the project.

3. $ mvn test

Triggers Maven to run the tests present in the .../src/test folder

4. Download sources of dependencies, check the default settings of maven
$ mvn -X
Load sources

$mvn dependency:sources

5. Run an individual module and skip the tests


$ mvn clean install -rf :ethoca-ejb -DskipTests

6.  build the JAR

mvn clean package
