How to make the Maven child project to have different version than the parent?

I am very new to Maven, and I am creating a Maven parent and child project. I want the child project to have a different version than the parent, but if I change the version, then I am getting the error Cannot resolve for some of the dependencies.

How can I have a have a parent version different than the child version?

Following are the current properties I have, which are working pretty fine:

<modelVersion>4.0.0</modelVersion>
<parent>
    <groupId>io.parent-test</groupId>
    <artifactId>io.parent-test</artifactId>
    <version>0.9.1-SNAPSHOT</version>
    <relativePath></relativePath>
</parent>

<artifactId>test-project-converter</artifactId>
<name>test-project</name>
<description>Test Project</description>

If I change the properties to include the different version for child then I get the error:


<modelVersion>4.0.0</modelVersion>
<parent>
    <groupId>io.parent-test</groupId>
    <artifactId>io.parent-test</artifactId>
    <version>0.9.1-SNAPSHOT</version>
    <relativePath></relativePath>
</parent>

<version>0.9.2-SNAPSHOT</version>
<artifactId>test-project-converter</artifactId>
<name>test-project</name>
<description>Test Project</description>

I have the following dependencies based on the version that is throwing the error:

<dependency>
    <groupId>io.parent-dep</groupId>
    <artifactId>parent-dev</artifactId>
    <version>${project.version}</version>
</dependency>

I tried to look into some of the responses online and made modifications to my parent project to include the properties:

<properties>
    <revision>0.9.2-SNAPSHOT</revision>
</properties>

and accordingly, change the child project to include the version <version>${revision}</version> but it's not working as expected.

Can someone please let me know how can I create a different snapshot version for my child project while keeping the parent project same?

Solution

  • I was able to fix it by providing the parent version ${project.parent.version} to the dependencies coming from the parent.

    I tried this, and everything worked fine.

    <modelVersion>4.0.0</modelVersion>
<parent>
    <groupId>io.parent-test</groupId>
    <artifactId>io.parent-test</artifactId>
    <version>0.9.1-SNAPSHOT</version>
    <relativePath></relativePath>
</parent>

<version>0.9.2-SNAPSHOT</version>
<artifactId>test-project-converter</artifactId>
<name>test-project</name>
<description>Test Project</description>

<dependencies>

<dependency>
    <groupId>io.parent-dep</groupId>
    <artifactId>parent-dev</artifactId>
    <version>${project.parent.version}</version>
</dependency>

</dependencies>
