我正在尝试从以下位置运行picketlink快速入门：
https://github.com/jboss-developer/jboss-picketlink-quickstarts
进一步来说：
https://github.com/jboss-developer/jboss-picketlink-quickstarts/tree/master/picketlink-federation-saml-idp-basic
但是在每次尝试安装Maven依赖项时，我都会遇到下一个错误：
Could not find artifact org.picketlink.distribution:picketlink-jbas7:jar:2.8.0.Beta1-SNAPSHOT
这是我
$ mvn clean package jboss-as:deploy之后的完整日志[INFO] Scanning for projects...

我已经看到您可能需要在您的maven文件夹中添加settings.xml，但是我不知道该文件的制作方法或内容。
最佳答案
正如您已经说过的那样，maven告诉您org.picketlink.distribution:picketlink-jbas7:jar:2.8.0.Beta1-SNAPSHOT依赖项丢失了，我相信这是因为您以前没有安装它。
如我所见，jboss-picketlink-quickstarts是一堆具有父级pom.xml的项目，您可以在其中找到作为模块的项目：
<module>picketlink-federation-saml-idp-basic</module>
因此，您必须克隆整个
jboss-picketlink-quickstarts项目并从父项目运行mvn install。这将带您所有需要解析到本地Maven存储库（通常为
~/.m2/repository）的依赖项。试试看，它将解决您的依赖性。有时，您必须使用
-U调用maven来强制-SNAPSHOT依赖性。希望能帮助到你！
