使用 maven-enforcer-plugin 解决依赖收敛错误的策略
Strategy for resolving dependency convergence errors with maven-enforcer-plugin
我正在尝试在我的应用程序中使用 Neo4j 的嵌入式 InProcess 服务器。同时，我们需要修复 Maven maven-enforcer-plugin 并强制执行 dependencyConvergence 规则以保持依赖项干净整洁。
这是我正在谈论的项目：https://github.com/k-kalinowski/GraphDatabase
现在，我决定采用解决收敛错误的策略，如下所示：选择满足最明确依赖关系的工件版本并将其放入 dependencyManagement。
在 dependencyManagement 部分完成一些清理后，我能够使项目通过 dependencyConvergence 规则并最终编译它。在 运行 测试时，我遇到了一些运行时异常，我猜这是由于我弄乱了我在 dependencyManagement 部分中选择的正确工件的版本。

好的，看来我在模块中的清理工作还不错。经过一些调查，它就像 neo4j-ogm-1.1.3 MetaData 匹配器中的错误。默认情况下，@Relationship 的注释字段类型是在 CamelCase 中生成的，而对于 @RelationshipEntity 它是用下划线生成的，所以当 Neo4j-ogm 试图匹配给定关系字段的关系实体时，它找不到 none。快速修复是手动提供匹配类型
例如。变化：
@Relationship
private AdminAction adminAction;
和
@RelationshipEntity
public class AdminAction {
至：
@Relationship(type = "ADMIN_ACTION")
private AdminAction adminAction;
和
@RelationshipEntity(type="ADMIN_ACTION")
