我想要添加几何形状的数据库，因此我需要空间插件。但是由于某些版本错配，我无法运行我的项目。

工件org.neo4j:neo4j-spatial的更新版本(自2014年以来)可在neo4j-contrib Maven存储库中使用。这个存储库可以在https://raw.github.com/neo4j-contrib/m2/master/releases上使用。

按照这里的说明，必须将这个存储库添加到您的pom.xml中：

<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>

但是，这个发行版存储库中的最新版本是

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

到目前为止，版本0.25.5-neo4j-3.4.0是在git回购中的主分支的版本，但是它看起来还没有发布到Maven存储库。最好的选择是使用上面提到的3.3.5版本，但是如果绝对需要3.4.0版本，您可以再等几天，希望它在Maven存储库中可用，或者您可以按照这些指示自己构建版本。
