java - 尝试设置 Maven Nexus 服务器但收到 "Could not resolve dependencies"

Question

尝试设置 Maven Nexus 服务器，但仅在某些包上出现“无法解析依赖项”。

有人可以告诉我为什么会收到此错误吗？

Answer 1

问题不在于您的项目，也不在于您的 settings.xml 文件。

Maven 将联系您的本地主机 Nexus 存储库来查找 org.springframework.webflow:spring-faces:jar:2.3.1.BUILD-SNAPSHOT显然没有找到它。

您的本地 Nexus 存储库中是否存在此 Artifact ？您是否在 Nexus 中设置了其他存储库，以便它可以获取它没有的 Artifact ？
