I have a spring boot application which has rest call to the neo4j. I am using following maven dependency -
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-neo4j-rest</artifactId>
<version>3.3.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-neo4j</artifactId>
<version>3.3.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-rest</artifactId>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-commons</artifactId>
<version>1.10.2.RELEASE</version>
</dependency>
With Neo4j 2.2.3, Rest App was working fine. After i upgraded Neo4j to 2.3.3, Rest App is not woking. I am getting dependency issue. Maven is not able to download Neo4j 2.3.3 jars, even though i tried with latest version of artifacts for spring-data-neo4j-rest (3.4.4.RELEASE) and spring-data-neo4j(4.0.0.RELEASE). Please let me know which artifact version of spring-data-neo4j-rest and spring-data-neo4j to use for Neo4j 2.3.3. Here is the errors which i am getting -
