Import from other module

Question

I write project using Java and Maven. In project I have many modules. My problem is that I can not import classes from other module.

My project structure looks like this:

Project  |_ module1     |_ src        |_ com.xyz.project.md1           |_ Person.java     |_ pom.xml <- pom of module1  |_ module2     |_ src        |_ com.xyz.project.md2           |_ Robot.java     |_ pom.xml <- pom of module2  |_ pom.xml <- main Project pom 

module1 and module2 are Modules in my project, which are registred in pom.xml - main Project pom

And when I am in Person.java from module1 I want import the Robot.java from module2 but I can not do this with import com.xyz.project.md2.Robot. Why ?

Answer 1

Declare dependency to module2 in module1/pom.xml, something like this:

<dependencies>     ...             <dependency>                 <groupId>XX</groupId>                 <artifactId>module2</artifactId>                 <version>0.0.1-SNAPSHOT</version>             </dependency>     ... </dependencies>
