Question

在我的项目中，我正在使用neo4j 2.2.5版，它与lucene中的pom.xml依赖项冲突，因为我检查了相同的代码而没有lucene依赖，这很好，所以如何在没有冲突的情况下在同一个项目中使用lucene和neo4j。

Answer 1

在一个Maven项目中无法使用Neo4j和最新版本的Lucene。 Neo4j正在使用3.6版本。

您有两个选择

编写自己的类加载器
- Java Class Loaders
使用Maven Shade插件
- https://maven.apache.org/plugins/maven-shade-plugin/
- https://github.com/lagodiuk/neo4j-uber-jar/blob/master/pom.xml

java.lang.RuntimeException：启动org.neo4j.kernel.EmbeddedGraphDatabase
