如何在Nexus存储库中使用Spring快照

Question

我们可以使用Nexus存储库构建Spring Boot发布项目，该存储库代理maven-central并使用maven-public组。Spring Boot快照项目将不会构建，因为Maven无法解析快照依赖项。Spring快照被下载了，但是我们得到了这个错误消息。

Failure to find org.springframework.cloud:spring-cloud-starter-zipkin:jar:2.2.0.BUILD-SNAPSHOT
in http://[host]:8081/repository/[snapshots] was cached in the local
repository, resolution will not be reattempted until the update
interval of [snapshots] has elapsed or updates are forced

以下是设置：

pom如下所示：

我尝试过使用和不使用Nexus proxy for Spring Snapshot进行构建，但都没有帮助。

问题是2.2.0.BUILD-SNAPSHOT目前还不能在http://repo.spring.io/snapshot上公开使用。可用的最高版本是2.1.2.BUILD-SNAPSHOT。我正在与一位Pivotal员工合作，他必须比公众更早地访问更高的内部版本号。我把我的pom.xml版本降到了2.1.1版本，它起作用了。
