You can get the source and log issues on GitHub.

A minimal Maven set of dependencies typically looks like the following:

pom.xml. 

<dependencies>
  <!-- ... other dependency elements ... -->
  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
  </dependency>
  <dependency>
    <groupId>org.springframework.security.oauth.boot</groupId>
    <artifactId>spring-security-oauth2-autoconfigure</artifactId>
    <version>2.1.0.M2</version>
  </dependency>
</dependencies>

All GA releases (i.e. versions ending in .RELEASE) are deployed to Maven Central, so no additional Maven repositories need to be declared in your pom.

If you are using a SNAPSHOT version, you will need to ensure you have the Spring Snapshot repository defined as shown below:

pom.xml. 

<repositories>
  <!-- ... possibly other repository elements ... -->
  <repository>
    <id>spring-snapshot</id>
    <name>Spring Snapshot Repository</name>
    <url>http://repo.spring.io/snapshot</url>
  </repository>
</repositories>

If you are using a milestone or release candidate version, you will need to ensure you have the Spring Milestone repository defined as shown below:

pom.xml. 

<repositories>
  <!-- ... possibly other repository elements ... -->
  <repository>
    <id>spring-milestone</id>
      <name>Spring Milestone Repository</name>
      <url>http://repo.spring.io/milestone</url>
  </repository>
</repositories>

A minimal Spring Security Gradle set of dependencies typically looks like the following:

build.gradle. 

dependencies {
  compile 'org.springframework.boot:spring-boot-starter-security'
  compile 'org.springframework.security.oauth.boot:spring-security-oauth2-autoconfigure:2.1.0.M2'
}

All GA releases (i.e. versions ending in .RELEASE) are deployed to Maven Central, so using the mavenCentral() repository is sufficient for GA releases.

build.gradle. 

repositories {
  mavenCentral()
}

If you are using a SNAPSHOT version, you will need to ensure you have the Spring Snapshot repository defined as shown below:

build.gradle. 

repositories {
  maven { url 'https://repo.spring.io/snapshot' }
}

If you are using a milestone or release candidate version, you will need to ensure you have the Spring Milestone repository defined as shown below:

build.gradle. 

repositories {
  maven { url 'https://repo.spring.io/milestone' }
}
