Netbeans上maven项目中的Spring-boot-start jar加载错误

Question

我从https://start.spring.io/加载了一个新的Spring Boot应用程序（版本2.0.0)，并尝试使用netbeans IDE构建它。

在maven构建过程中，我遇到了以下错误：

The build could not read 1 project -> [Help 1]

  The project com.deepit.springboot.example:spring-boot-in-deep:0.0.1-SNAPSHOT (~=NetBeansProjects\spring-boot-in-deep\pom.xml) has 1 error
    Non-resolvable parent POM: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.0.0.BUILD-SNAPSHOT from/to spring-snapshots (https://repo.spring.io/snapshot): repo.spring.io and 'parent.relativePath' points at no local POM @ line 14, column 10: Unknown host repo.spring.io -> [Help 2]

To see the full stack trace of the errors, re-run Maven with the -e switch.
Re-run Maven using the -X switch to enable full debug logging.
