找不到Spring Boot Starter Parent 2.0.0依赖项
我决定将spring-boot-starter-parent升级到2.0.0.M1版本，以便与Spring Core 5.0.0.RC1一起使用。
但是，我在从Spring里程碑存储库下载依赖项时遇到问题。
我的pom.xml

我有一个“ clean Sheat” .m2 settings.xml，并且已经清理了本地存储库，并确保可以连接到Spring里程碑存储库。

回答：
将Spring Plugin Release Repo添加到中Plugin-Repositories。这样就可以找到了spring-boot-maven-
plugin-2.0.0.M1.jar。我已经看到它包含在该回购中
将以下各行添加到<project>标记下，如下所示：
<project><!------ others lines -->
<pluginRepositories>
<pluginRepository>
<id>repository.spring.release</id>
<name>Spring GA Repository</name>
<url>https://repo.spring.io/plugins-release/</url>
</pluginRepository>
</pluginRepositories>
</project>
由于我没有com.test.testplugin，我已经检查了以下内容。请删除<dependencyManagement>和放在<dependencies>下面<project>。最终pom.xml看起来像：
<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0"
