Maven Dependency Conflict Resolution

There are several ways in which Maven can resolve dependency conflicts:

1. exception

<dependency>
    <groupId>group-a</groupId>
    <artifactId>artifact-a</artifactId>
    <version>1.0.0</version>
    <exclusions>
        <exclusion>
            <groupId>group-b</groupId>
            <artifactId>artifact-b</artifactId>
        </exclusion>
    </exclusions>
</dependency>

This can eliminate specific versions of conflicting dependencies, thus resolving the conflict.

1. By adjusting the order of dependencies: When Maven resolves dependencies, it follows a top-down approach. This means that if higher priority dependencies are listed first in the pom.xml file, conflicting dependencies will be resolved in favor of the higher priority.
2. By using Dependency Management in a Maven parent-child project structure, dependencies can be declared in the parent project’s pom.xml file using the dependencyManagement tag, and then referenced in the child project. This allows the child project to inherit the dependency versions from the parent project, helping to avoid conflicts by managing dependencies consistently.
3. Utilize plugins provided by Maven: Maven offers various plugins to tackle dependency conflicts, such as maven-enforcer-plugin and maven-dependency-plugin, which can be used by invoking the plugin’s target command to resolve dependency conflicts.

These methods can be chosen based on the specific dependency conflict situation to find a suitable solution.
