如何将同一个程序包的多个版本作为项目的间接依赖项？

Question

I'm working on a project which connects to Elasticsearch 5.2.1 and Neo4j 3.1.0 at the same time. These two packages both make use of Lucene but unfortunately incompatible versions. Elaticseach needs Lucence 6.4.1 and Neo4j works with Lucene 5.5.0.

As the result, I'm facing with runtime errors since some of the classes have incompatible signatures. Is there any way I can have both Elasticsearch and Neo4j (with the given versions) in one project?

What I'm trying to do is to add Elasticsearch package to this project . And here are the Elasticsearch dependencies that I added:

    <dependency>
        <groupId>org.elasticsearch</groupId>
        <artifactId>elasticsearch</artifactId>
        <version>5.2.1</version>
    </dependency>
    <dependency>
        <groupId>org.elasticsearch.client</groupId>
        <artifactId>transport</artifactId>
        <version>5.2.1</version>
    </dependency>

How can I make these two to play alongside of each other nicely?

jar的每个组合都应打包在具有依赖项或war的不同jar中，并且它们不应共享同一父类加载器，以便在具有依赖项或war的jar的两个不同版本中退出的已加载类由不同的classloader加载。
