Missing artifact when trying to add spring-data - spring

Question

I am trying to add the spring data dependency to my Spring boot starter project but I am getting the error: Missing artifact org.springframework.data:spring-data-jdbc-ext:jar:1.0.0.RELEASE
Here is my pom.xml file. What am I missing here?

Answer 1

For some reason the documentation on the Spring Data JDBC Extensions website is wrong (or the distribution is wrong!).
According to that page you, indeed, need to include the dependency you mention.
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jdbc-ext</artifactId>
<version>1.0.0.RELEASE</version>
</dependency>
However if you take a look in the spring repository for that artifact it contains a zip file with the release instead of a jar or pom file.
The spring-data-jdbc-ext project consists of 2 artifacts, which both are available. Change your dependency to the following
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jdbc-core</artifactId>
<version>1.0.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-oracle</artifactId>
<version>1.0.0.RELEASE</version>
</dependency>
If you don't need the specific Oracle extensions than you could leave that one out.
A small note there is a 1.1.0.M1 version also (a milestone/pre-release versio) which works with a newer version of Spring Data. You might want to try that instead of the 1.0.0.RELEASE version which was build against an older version of Spring Data.
