Apache Maven Beginner to Guru - Example of Maven Bill of Materials (BOM)

The video tutorial explains how to use a bill of materials (BOM) in a multi-module Maven project. It covers refactoring to centralize dependency management, focusing on MapStruct and handling transitive dependencies. The tutorial emphasizes organizing version properties for easier maintenance and concludes with finalizing the setup in a GitHub branch.

What is the primary purpose of using a bill of materials in a Maven project?

• To compile the project faster

• To manage and centralize dependency versions

• To increase the project's security

• To list all available plugins

Why is it beneficial to centralize properties in a Maven project?

• It simplifies version management

• It makes the project more secure

• It reduces the project's size

• It speeds up the build process

What happens to a dependency line in a child module when its version is managed in the parent POM?

• It becomes optional

• It is removed from the child module

• It is ignored during the build

• It is duplicated in the child module

What is a transitive dependency in Maven?

• A dependency that is directly declared

• A dependency that is not used

• A dependency that is optional

• A dependency that is automatically included through another dependency

How does managing transitive dependencies benefit a Maven project?

• It increases the project's complexity

• It ensures consistent versions across modules

• It reduces the number of dependencies

• It speeds up the build process

What is the advantage of externalizing version properties in Maven?

• It makes the project more secure

• It allows for easier updates and maintenance

• It speeds up the build process

• It reduces the project's size

What should typically be avoided in the dependency management section of a Maven POM?

• Using transitive dependencies

• Declaring version properties

• Providing the scope

• Listing all dependencies
