3fill in blank

hard

Fix the error in the dependency declaration by completing the missing tag.

💡 Hint

Common Mistakes

Using <scope> instead of <version> when version is missing.

Omitting the version tag entirely.

The <version> tag specifies which version of the dependency to use. Without it, Maven may not know which version to download.

  <artifactId>[2]</artifactId>
</dependency>

Using unrelated groupId with a Spring Boot artifactId.

The groupId org.springframework.boot and artifactId spring-boot-starter-security together specify the Spring Boot security starter dependency.
