Managing dependencies in Spring Boot can be tricky. Issues like conflicts, missing dependencies, bloated applications, and incorrect scopes can cause runtime errors and unexpected behavior. Let’s break it down and fix these problems!

Common Dependency Issues & Their Solutions
1️⃣ Dependency Conflicts
Use dependency management to enforce specific versions.
Run mvn dependency:tree (Maven) or gradle dependencies (Gradle) to detect conflicts.

Example (Maven):
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>2.7.2</version>
</dependency>
</dependencies>
</dependencyManagement>


2️⃣ Unnecessary Dependencies
Remove unused dependencies to improve performance and security.
Run mvn dependency:analyze (Maven) or gradle dependencies –scan (Gradle) to check for unnecessary dependencies.

3️⃣ Missing Dependencies
Ensure all required dependencies are included in pom.xml or build.gradle.
If a dependency isn’t available, check if the correct repository is used:
<repositories>
<repository>
<id>central</id>
<url>https://repo.maven.apache.org/maven2</url>
</repository>
</repositories>

4️⃣ Incorrect Dependency Scope
Use the right scope (compile, test, runtime) to prevent errors in different build phases.

Example (Test Dependency in Maven):
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-api</artifactId>
<version>5.7.0</version>
<scope>test</scope>
</dependency>
