检查多模块 Maven 项目中的依赖版本

Question

I have this dependencyManagement in my parent POM of my multi-module project:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>${project.groupId}</groupId>
            <artifactId>A</artifactId>
            <version>3.5</version>
        </dependency>
        <dependency>
            <groupId>${project.groupId}</groupId>
            <artifactId>B</artifactId>
            <version>1.0</version>
        </dependency>
        <dependency>
            <groupId>${project.groupId}</groupId>
            <artifactId>C</artifactId>
            <version>1.1</version>
        </dependency>
</dependencyManagement>

And this in every child module POM:

Module A:

<parent>
    <groupId>${project.groupId}</groupId>
    <artifactId>ParentId</artifactId>
    <version>1.0</version>
</parent>
<artifactId>A</artifactId>
<version>3.5</version>
<packaging>nbm</packaging>

Module B:

<parent>
    <groupId>${project.groupId}</groupId>
    <artifactId>ParentId</artifactId>
    <version>1.0</version>
</parent>
<artifactId>B</artifactId>
<version>1.0</version>
<packaging>nbm</packaging>

Module C:

<parent>
    <groupId>${project.groupId}</groupId>
    <artifactId>ParentId</artifactId>
    <version>1.0</version>
</parent>
<artifactId>C</artifactId>
<version>1.1</version>
<packaging>nbm</packaging>

Every time that we want to release, we have to check that the version in every child module is the same that the version in the dependencyManagement (developers are asked to change the version in both places every time they change something).

There is some way to check that the versions are the same automaticaly? If the versions are not the same, how could I change them automaticaly?

Parent pom discovery-ui :

<parent>
    <groupId>${project.groupId}</groupId>
    <artifactId>discovery-ui</artifactId>
    <version>1.0</version>
</parent>

<properties>
        <A.version>3.5</A.version>
        <B.version>1.0</B.version>
        <C.version>1.1</C.version>
<properties>
        
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>${project.groupId}</groupId>
            <artifactId>A</artifactId>
            <version>${A.version}</version>
        </dependency>
        <dependency>
            <groupId>${project.groupId}</groupId>
            <artifactId>B</artifactId>
            <version>${B.version}</version>
        </dependency>
        <dependency>
            <groupId>${project.groupId}</groupId>
            <artifactId>C</artifactId>
            <version>${C.version}</version>
        </dependency>
</dependencyManagement>

Module A:

<parent>
    <groupId>${project.groupId}</groupId>
    <artifactId>discovery-ui</artifactId>
    <version>1.0</version>
</parent>
<artifactId>A</artifactId>
<version>${A.version}</version>
<packaging>nbm</packaging>

Answer 2

Have you tried maven versions plugin ? Looks like processParent parameter should do the trick. I have not tested it yet, though.

mvn versions:set -DgenerateBackupPoms=false -f A/pom.xml -DnewVersion=NEW_VERSION -DartifactId=A -DprocessParent=true

Answer 3

You already have declared dependencies and their versions in your parent POM under the <dependencyManagement> section. This way you need only to declare GroupID:ArtifactID in your child POM (without version, it will be inherited from the parent POM)
