|-- modP

|   |-- pom.xml

|   |-- src

|   |   |-- main

|   |     `-- java

|   |                     `-- modC

          `-- java

              `-- com

                  `-- myorg

                      `-- myapp

                          `-- modC2

                              `-- AppN.java

My pom.xml for modP 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">

    <modelVersion>4.0.0</modelVersion>



  <groupId>com.myorg.myapp</groupId>

  <artifactId>modP</artifactId>

  <version>0.0.1-SNAPSHOT</version>

  <packaging>pom</packaging>



  <name>modP</name>

  <url>http://maven.apache.org</url>



  <properties>

    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

  </properties>



  <dependencies>

    <dependency>

      <groupId>junit</groupId>

      <artifactId>junit</artifactId>

      <version>3.8.1</version>

          <scope>test</scope>

    </dependency>

  </dependencies>

</project>

My pom.xml for C1 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">

<parent>

    <artifactId>modP</artifactId>

    <groupId>com.myorg.myapp</groupId>

    <version>0.0.1-SNAPSHOT</version>

    <relativePath>.../modP/pom.xml</relativePath>

</parent>

<modelVersion>4.0.0</modelVersion>



  <groupId>com.myorg.myapp</groupId>

  <artifactId>modC1</artifactId>

  <packaging>jar</packaging>



  <name>modC1</name>

  <url>http://maven.apache.org</url>

</project>

And pom.xml for C2 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">

<parent>

    <artifactId>modP</artifactId>

    <groupId>com.myorg.myapp</groupId>

    <version>0.0.1-SNAPSHOT</version>

    <relativePath>.../modP/pom.xml</relativePath>

</parent>

<modelVersion>4.0.0</modelVersion>



  <groupId>com.myorg.myapp</groupId>

  <artifactId>modC2</artifactId>

  <packaging>jar</packaging>



  <name>modC2</name>

  <url>http://maven.apache.org</url>

</project>

My question is can I using such configuration reference AppP.java from ModP in AppC1.java and AppC2.java in ModC1 and ModC2.

I tried this and it looks like this doesn’t works. Did I misunderstood meaning of parent tag in pom.xml? What I need to do in maven for such function?

I read a lot of documentation, but now I’m even more confused than before reading. 🙁

Every answer will be highly appreciated.

Thanks

Answer 1

Since ModP is a pom (packaging) project, it should not contain any Java code.
