Nexus 存储库 - 找不到工件 - 我该如何调试？
Nexus Repository - Could not find artifact - how do I debug this?
我们正在使用 nexus 而不是直接访问 public maven 存储库。
我收到以下简化错误：

我检查了 nexus 存储库并看到以下内容：
指数
/repositories/sg-snapshots/org/menios/bakos/group/project/spring-cloud-skipper-maven-plugin/0.1.2-快照
问题
我该如何解决这个问题？
问题是上传到 nexus 的实际快照文件的名称更复杂，例如spring-cloud-skipper-maven-plugin-0.1.2-20180305.114852-2.pom ?
问题不在于文件名中的时间戳（这是标准的）。几种可能性是：
- 您的本地存储库缓存了工件的 non-existence 或者只是损坏了。从本地存储库中删除相关目录（通常位于 user/.m2/repository）
- 你的 maven 有一个错误的 settings.xml，它没有包含正确的 Nexus（或者镜像定义是错误的）。
- 您的 Nexus 使用存储库组，但不包括相关存储库。
- 您的 Nexus 元数据已损坏。尝试重新创建它们。
问题是这是一个 plugin 而我在 <pluginRepositories>.
中遗漏了一个条目
一旦我为 snapshots 和 releases 添加了两个条目，一切就开始正常工作了！
我们正在使用 nexus 而不是直接访问 public maven 存储库。
