当我从pom.xml中删除以下依赖项时，代码会正常构建。

<dependency>
            <groupId>com.atlassian.jira</groupId>
            <artifactId>jira-rest-java-client-core</artifactId>
            <version>5.2.1</version>
</dependency>

但是当我建立这种依赖性时，会出现以下错误。

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。

Answer 1

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。

Answer 2

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>
  <dependency>
<dependencies>
