Java OpenSAML3缺少工件

尝试在eclipse中构建一个小样本项目（尝试了eclipse的火星和氧气释放）。使用Java1.8。当我添加opensaml依赖项时，它在opensaml saml impl上失败，表明：

Missing artifact org.apache.commons:commons-collections:jar:3.2.1
Missing artifact org.apache.commons:commons-lang:jar:2.6
Missing artifact org.apache.jakarta:oro:jar:2.0.8

具有以下pom.xml的空项目：

我已尝试在底部添加存储库，但没有更改：

有人知道为什么吗？我尝试过“更新项目…”，尝试过作为maven项目删除/添加，尝试过一个空的新项目，尝试过将oxygen作为新ide安装，但仍然遇到同样的问题。

通过一系列步骤解决。最终，我认为最后一步是解决问题的主要步骤（maven build）。以下是系列：

• 删除整个本地存储库（您的.m2/存储库）
• 删除了对旧JVM的所有引用
• 重新启动的eclipse
• 多次重置为Java1.8接口，当我选择maven |“Update Project…”时，maven中的某些东西认为它是JVM1.5
• 根据Mike Salleses的回答运行Maven构建
  • 作为| maven build |目标“干净安装-U”运行|运行

maven构建是一种我从未见过的新技术。它基本上构建了包含maven拉取的项目，您可以以日志样式的格式查看失败的细节

maven构建最终强制下载所有JAR并编译。此时，其余的测试项目都使用了干净的构建。

您是否尝试将那些缺少的jar依赖项也添加到pom中？是的，尝试使用3.2.1版本手动添加commons集合，如错误中所示。没有变化。
