我该如何解决？我尝试使用不同版本的jira-rest-java-client-core，但结果是相同的。我已经阅读了有关排除的内容，但不确定如何使用它们来解决我的问题。
解决方法
依赖性收敛错误是通过使用<dependencyManagement>中的条目而不是使用排除项来解决的。
您执行以下操作：
- 您查看列表中哪些传递性依赖项出现在多个版本中。
- 您选择所需的版本（通常是最新版本）。
- 您可以在POM的
<dependencyManagement>部分中添加一个条目，在其中指定此版本。 - 然后，该条目将覆盖不同的传递依赖项。
该问题与传递依赖关系有关，您可以通过在dependencyManagement中移动冲突的依赖关系来解决此问题
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.atlassian.jira</groupId>
<artifactId>jira-rest-java-client-core</artifactId>
<version>5.2.1</version>
<dependency>
<dependencies>
<dependencyManagement>
然后在“依赖项”部分定义没有任何版本的依赖项
<dependencies>
<dependency>
<groupId>com.atlassian.jira</groupId>
<artifactId>jira-rest-java-client-core</artifactId>
