How to add reference of Mavenized Projects

Question

I have two mavenized projects

1. Project_A: Java Project
2. Project_B: Java Web Project

Earlier, before mavenizing both projects, i had refrence(buildpath) of Project_A in Project_B. Now i have configured both projects with maven2. MY questions is, how can i add a refrence of Project_A in Project_B that WAR of Project_B can be runnable

so far i have tried following chunk of code which seems to work but on runtime Project_B's WAR throw an exception in applicationContext that an Instance of Project_A's class cannot be initiated.

1- Project_A is cleaned and installed in local repository with name "myproject-1.0.jar" where build snippet(Project_A's POM) is as follows#

Edited Part

  <modelVersion>4.0.0</modelVersion>
   <groupId>org.myurl<groupId>
<artifactId>projectA</artifactId>
<version>1.0</version>
<packaging>jar</packaging>
<name>${project.artifactId}-${project.version}</name>




build>
        <sourceDirectory>${basedir}/src/main/java</sourceDirectory>
        <outputDirectory>${basedir}/target/classes</outputDirectory>
        <testSourceDirectory>${basedir}/src/test/java</testSourceDirectory>
        <testOutputDirectory>${basedir}/target/test-classes</testOutputDirectory>
        <resources>
            <resource>
                <directory>${basedir}/src/main/resources</directory>
            </resource>
        </resources>
        <testResources>
            <testResource>
                <directory>${basedir}/src/test/resources</directory>
            </testResource>
        </testResources>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.6</source>
                    <target>1.6</target>
                    <optimize>true</optimize>
                </configuration>
            </plugin>

        </plugins>
    </build>

1. Snippet of Project_B's POM, where i am adding installed jar of Project_A

            <dependency>
       <groupId>org.myurl</groupId>
       <artifactId>projectA</artifactId>
       <version>1.0</version>
       <scope>compile</scope>
   </dependency>
   

Thanks for suggestions in advance.

Answer : Actually there was not any problem with maven. Above configurations in POM are absolutely correct. I had moved properties files under /Resources and later i have forgotten to change paths in those classed where properties files are utilized.

Nevertheless i am thankful to Dolphin and Nicola Musatti for their suggestions.

Answer 1

You are on good way, pom snippet is fine what you need to do now is make parent project (Maven Reactor). So you will make new project and in that project define modules (Project A and Project B). You will reference that parent in Project A and Project B, and that will do the trick. Google maven parent to see how it's done.

After building Project B, maven will first build Project A and after that Project B.

Thing is your approach should work as well (just it's not a proper way to do it). So probably you are making mistake in groupId, version. You can check this by build Project A and then checking your local maven repository. Inside of it you should see folder structure if not something went wrong.

org/myurl/projectA-1.0.jar

Project strucuture is following:

project-parent project-a project-b

in project parent you define:

<groupId>foo.bar</groupId>
<artifactId>project-parent</artifactId>
<version>00.01-SNAPSHOT</version>
<name>FooBar:: Parent Project</name>
<packaging>pom</packaging>

<modules>
    <module>../project-a</module>
    <module>../project-b</module>
</modules>

in project-a and project-b you add:

<parent>
    <groupId>foo.bar</groupId>
    <artifactId>project-parent</artifactId>
    <version>00.01-SNAPSHOT</version>
</parent>

In project-b you will have reference to project-a

    <dependency>
        <groupId>foo.bar</groupId>
        <artifactId>project-a</artifactId>
        <version>00.01-SNAPSHOT</version>
    </dependency>

Once you build parent it should build all modules correctly. Don't use plugin, forget I said Maven Reactor :)
