Maven 在 Maven Central 中找不到现有的依赖项

Question

我有一个新的Spring Boot 2.5.3项目，遇到了一些奇怪的问题。我试图在我的pom.xml中添加此依赖项，但由于某些原因Maven 3.6.3无法解决此依赖项。

<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi</artifactId>
<version>1.5.10</version>
</dependency>

当从IDE (IntelliJ)和命令提示符(bash/cmd)运行mvn clean install -U时，打印的异常是

这个依赖项存在于Maven Central中，这让事情变得很奇怪。

在Windows和CentOS操作系统的两台不同的机器上尝试，结果是相同的。

Answer 1

这个依赖项没有jar类型。只有POM类型。

您需要使用与Maven Central建议的相同的依赖声明:

<!-- https://mvnrepository.com/artifact/org.springdoc/springdoc-openapi -->
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi</artifactId>
<version>1.5.10</version>
<type>pom</type>
</dependency>

Answer 2

试着做一个maven clean install

clean目标应该重新编译项目并识别新的依赖项。如果这不起作用，请尝试关闭IDE并重新启动它。

如果依赖项实际上是在Maven中心，我有信心clean目标将工作。

这两个选项在过去解决依赖问题时都对我有效。
