Question

我们正在使用nexus而不是直接访问公共maven存储库。

我收到以下简化错误：

无法找到artif act org.menios.bakos.group.project：spring-cloud-skipper-maven-plugin：jar：0.1.2-SNAPSHOT

我检查了nexus存储库并看到以下内容：

索引 /repositories/sg-snapshots/org/menios/bakos/group/project/spring-cloud-skipper-maven-plugin/0.1.2-SNAPSHOT

问题

我该如何解决这个问题？上传到nexus的实际快照文件的名称是否具有更复杂的名称，例如spring-cloud-skipper-maven-plugin-0.1.2-20180305.114852-2.pom？

Answer 1

问题不在于文件名中的时间戳（这是标准的）。有几种可能性：

您的本地存储库缓存了工件的不存在或者只是破坏了。从本地存储库中删除相关目录（通常位于 user /。m2 / repository下）
您的maven有一个错误的settings.xml，其中不包含正确的Nexus（或镜像定义错误）。
您的Nexus使用存储库组，但不包含相关存储库。
您的Nexus的元数据已损坏。尝试重新创建它们。

Answer 2

问题是这是一个plugin而我错过了<pluginRepositories>中的一个条目。

我为snapshots和releases添加了两个条目后，一切正常！

Nexus存储库 - 找不到工件 - 我该如何调试？
