Question

When i add this below dependency to my project:

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-oauth2-client</artifactId>
</dependency>

I get this error when running project using clean spring-boot:run -Pdev in intellij idea:

Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.3.1.RELEASE:run (default-cli) on project webapp: Could not exec java

I also has this warning in logs:

[WARNING] Could not transfer metadata net.minidev:json-smart/maven-metadata.xml from/to spring-milestones (https://repo.spring.io/libs-milestone): Authentication failed for https://repo.spring.io/libs-milestone/net/minidev/json-smart/maven-metadata.xml 401 Unauthorized

You need to use starters, otherwise you may have missing dependencies and unexpected exceptions

    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-oauth2-client</artifactId>
    </dependency>

here is full xml
