Maven can resolve package conflicts in the following ways:

  1. Tags exclude specific dependencies. For example:
<dependency>
  <groupId>org.example</groupId>
  <artifactId>example</artifactId>
  <version>1.0</version>
  <exclusions>
    <exclusion>
      <groupId>org.example</groupId>
      <artifactId>conflicting-dependency</artifactId>
    </exclusion>
  </exclusions>
</dependency>
  1. Tags specify the specific version of the project being used. For example:
<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>org.example</groupId>
      <artifactId>conflicting-dependency</artifactId>
      <version>1.0</version>
    </dependency>
  </dependencies>
</dependencyManagement>
  1. Reorder Dependencies: Maven’s resolution of dependencies could lead to package conflicts. Trying to resolve conflicts by adjusting the order of dependencies. Dependencies can be reordered in the pom.xml file.
  2. Use the new version: If there are two conflicting dependencies, you can try updating one of the dependencies to resolve the conflict. You can specify a specific version by changing the tag.
  3. Utilize plugins: Maven provides plugins like maven-enforcer-plugin and maven-versions-plugin to help resolve package conflicts. These plugins can check dependencies during the build process, provide detailed information about conflicts, and offer solutions.

In conclusion, Maven offers various ways to resolve package conflicts, and developers can choose the most suitable method based on specific circumstances.
