I also had a difficult time setting up a spring-batch-admin project, as there is not much guidance to find on the net. Finally I found this sample project, which is a good starting point.
If you are using STS you can access it via: File -> New -> Spring project -> Batch -> Simple Batch Admin Webapp
EDIT: As for the spring-batch-admin-manager 1.3.0 I dont't see a final release out there as well. But you could give a try to the latest milestone, which seems to be stable enough to be included in the afromentioned sample project.
Put this in your pom.xml
<dependency>
<groupId>org.springframework.batch</groupId>
<artifactId>spring-batch-admin-manager</artifactId>
<version>1.3.0.M1</version>
</dependency>
<repository>
<id>spring-milestones</id>
<url>http://repo.springsource.org/libs-milestone/</url>
</repository>
Good luck!
