converting project to maven using eclipse

Question

I am trying to convert my current application into maven. I am separating the code into different modules.

Its a web application which has

 Controller package
 Model package
 services packages 
 DAO packages
 mybatis package which has interface to interact with database
 WEB-INF Folder which contains all jsps inside /jsp folder  

I created different modules I created a core module which right now has

 service package
 DAO Package
 src/main/webapp/WEB-INF

I created Model module which has all model classes and I am able to compile it successfully.

Now I am trying to compile mybatis package which is giving me error

   /home/.../mybatis/db/mybatis/dao/usersmapper.java :[7,54] error:
   package com.mycom.myproject.mybatis.db.mybatis.model does not exist

as usersmapper.class already been created with model module.

So I am not getting what I am doing wrong.

My main pom.xml is

   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Please let me know if you need any more information.

Answer 1

Your mybatis module is missing the dependency to your model project. A dependency basically includes the classes of another project in the compile classpath of a module.

So, include:

<dependency>
  <groupId>com.myproject</groupId>
  <artifactId>model</artifactId>
  <version>${project.version}</version>
</dependency>

in your mybatis module, and you should be good to go.
