Answer 1

我可以通过以下步骤解决问题。

将SpringBoot版本1.4.3.RELEASE更新为1.5.14.RELEASE。
关闭月食。
已删除的.m2目录。
在eclipse中打开项目。
Maven更新项目。

Answer 2

不确定为什么将javaxt添加为存储库，但是它给spring-boot-starter-parent提供了错误的内容。

只需单击http://www.javaxt.com/maven/org/springframework/boot/spring-boot-starter-parent/1.4.3.RELEASE/spring-boot-starter-parent-1.4.3.RELEASE.pom，您将看到内容。它应该是pom，但不是。

我建议删除或替换存储库。

Answer 3

如果XML格式正确并且存储库没有问题，请尝试使用早期版本的Spring boot starter。示例-

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.2.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

进行一次Maven更新，它应该可以工作。

不可解析的POM SpringBoot
