Maven构建-对核心类的依赖

Question

I have two projects I am working on which share some common code - I am putting this common code in to a new project called Core.

Both my projects use maven to build, and my core classes will also use maven. In Eclipse how do I configure maven to do a maven build of the core classes and then use these in the build for my two other applications?

Is there some prebuilt rule I need to specify - for example build this project, however, go build core first and use the output of that for this.

Hope that makes some sort of sense.

Answer 1

You can add a dependency to Core artifact in your project.

If you use M2E Eclipse plug-in , workspace artifacts are quite easy to reference in the Maven editor.

The only condition for this kind of dependency to work is that dependent artifact must be retrievable from a maven repository (eventually putting it to the local maven repository through install goal).

Answer 2

You could add a parent pom, with modules

<project>
    <groupId>com.mypackage</groupId>
    <artifactId>parent</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>pom</packaging>
    <name>parent</name> 
    <packaging>pom</packaging>
...
<modules>
  <module>Core</module>
  <module>MyModuleA</module>
  <module>MyModuleB</module>
</modules>
...
</project>

And then just add your dependency in MyModuleA and MyModuleB like a normal dependency

<dependency>
    <groupId>com.mypackage</groupId>
    <artifactId>Core</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</dependency>
