EclipseLink + Maven: java.lang.NoClassDefFoundError: javax/persistence/Persistence - maven

Question

My Persistence.xml is as follows:
<persistence-unit name="SARMPersistentUnit" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>edu.deakin.sarms.model.StudentAccount</class>
<class>edu.deakin.sarms.model.LecturerAccount</class>
<class>edu.deakin.sarms.model.Unit</class>
<class>edu.deakin.sarms.model.Enrollment</class>
<class>edu.deakin.sarms.model.Attendance</class>
<properties>
<property name="javax.persistence.jdbc.url" value="jdbc:mysql://xx.yy.ss:3306/t2"/>
<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
<property name="javax.persistence.jdbc.user" value="xx"/>
<property name="javax.persistence.jdbc.password" value="ee"/>
<property name="eclipselink.ddl-generation" value="drop-create-tables"/>
</properties>
</persistence-unit>
pom.xml is as follows:

Still I am getting "java.lang.NoClassDefFoundError: javax/persistence/Persistence", on the line:
public static EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("SARMPersistentUnit");
Can anyone please suggest what am I doing wrong?
Cheers

Answer 1

I was doing a mvn clean install and then java -jar . Then I used the command mentioned by #ajozwk in the comment, but I had another issue, the persistence.xml file was under src/main/ instead of src/main/resources. So now my problem is fixed!
