Missing artifact Spring data cassandra 1.5.0M1

Question

I try to use spring data cassandra 1.5.0, but when I update my pom by adding

<dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-cassandra</artifactId> <version>1.5.0.M1</version> </dependency> 

 <repositories> <repository> <id>spring-milestones</id> <name>Spring Milestones</name> <url>https://repo.spring.io/libs-milestone</url> <snapshots> <enabled>false</enabled> </snapshots> </repository> 

But I got an error

 Missing artifact org.springframework.data:spring-data-cassandra:jar:1.5.0.M1 

I need to use this version because of its support for cassandra 3.0.

The question is, how can I use this version?
