I want to add geometry shapes to database hence i need spatial plugin. But due to some version mismatch am not able to run my project..

Solution

  • The newer versions (since 2014) of the artifact org.neo4j:neo4j-spatial are available in the neo4j-contrib Maven repository. This repository is available at https://raw.github.com/neo4j-contrib/m2/master/releases.

    Following the instructions from here, you have to add this repository to your pom.xml:

    <repositories>
    <repository>
        <id>neo4j-contrib-releases</id>
        <url>https://raw.github.com/neo4j-contrib/m2/master/releases</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
    <repository>
        <id>neo4j-contrib-snapshots</id>
        <url>https://raw.github.com/neo4j-contrib/m2/master/snapshots</url>
        <releases>
            <enabled>false</enabled>
        </releases>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
</repositories>

    However, the latest version that is today available in this release repository is 

    <dependency>
  <groupId>org.neo4j</groupId>
  <artifactId>neo4j-spatial</artifactId>
  <version>0.25.5-neo4j-3.3.5</version> 
</dependency>

    As of today the version 0.25.5-neo4j-3.4.0 is the version of the master branch in the git repo but it looks like it has not yet been released to the Maven repository. The best option would be the use the 3.3.5 version mentioned above, but if the 3.4.0 version is absoluetly required, you could either wait for a few more days and hope it becomes available in the Maven repository or you could try to build the version yourself following these instructions.
