org.picketlink.distribution:picketlink-jbas7:jar:2.8.0.的POM丢失，则没有可用的依赖信息。

Question

我试着从以下几个方面运行快速启动：

https://github.com/jboss-developer/jboss-picketlink-quickstarts

更具体而言：

https://github.com/jboss-developer/jboss-picketlink-quickstarts/tree/master/picketlink-federation-saml-idp-basic

但是，在每次安装maven依赖项时，我都会得到下一个错误：

Could not find artifact org.picketlink.distribution:picketlink-jbas7:jar:2.8.0.Beta1-SNAPSHOT

这是我的$ mvn clean package jboss-as:deploy之后的全部日志

我已经看到，您可能需要向maven文件夹中添加一个settings.xml，但我不知道如何制作或放入该文件。

Answer 1

正如您已经说过的，maven告诉您缺少org.picketlink.distribution:picketlink-jbas7:jar:2.8.0.Beta1-SNAPSHOT依赖项，我相信这是因为您以前没有安装它。

正如我所看到的，jboss-picketlink-quickstarts是一组具有父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。

这将导致您使用需要解析到本地maven存储库(通常是~/.m2/repository)的所有依赖项。

试一试，它会解决你的依赖性。有时，您必须使用-U调用maven来强制-SNAPSHOT依赖项。

希望能帮上忙！
