Build failure due to missing libraries

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project spring-intergation: Compilation failure: Compilation failure:
[ERROR] \spring-intergation\src\main\java\uk\co\dd\spring\domain\User.java:[3,24] package javax.persistence does not exist

But i have added all the libraries in my eclipse by right clicking the project and adding the external jars.

When i try to run mvn compile i get these errors with a lot of other jars also missing.

The whole point of maven is that you describe all dependencies of your project in pom.xml rather than add them as jars in your IDE.

When you have dependencies configured in pom.xml, you can easily generate Eclipse project with the corresponding dependencies by running mvn eclipse:eclipse, or add them to the existing project with m2eclipse plugin.

Add this to your dependency 

<dependency>
  <groupId>javax.persistence</groupId>
  <artifactId>persistence-api</artifactId>  
  <version>1.0</version>
</dependency>
