我有要使用Maven在Intellij中导入的Java API,这就是我得到的:

  

无法解析插件org.springframework.boot:spring-boot-maven-plugin:

这是我的pom.xml文件:

到目前为止,我能找到的关于类似问题的唯一线索是this one 我从那里尝试了最新版本的解决方案,不幸的是它没有帮助。

我有用于项目结构的Java 8,并且我也尝试过使用Maven 3.6.2和3.6.1,因为一段时间前,我能够使用Maven 3.6.1将其导入另一台笔记本电脑。

我已经仔细检查了java和maven环境变量,我知道它们还可以。我也尝试过运行mvn clean install, mvn install, mvn package, mvn validate和我可以找到的任何其他命令,但问题仍然相同。

这是一个Spring启动项目,所以pom must have a parent。只需将这些行添加到pom.xml的顶部:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.3</version>
</parent>

此父级将处理依赖项的版本。

我的版本为 2.3.4 ,这在我的IntelliJ IDEA 2019.3.1(最终版)中引起了问题。将其更改回 2.3.2 可以为我解决此问题。现在我有以下配置:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.3.2.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>
