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

Question

我正在尝试运行picketlink快速入门：

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

更具体地说：

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

以下是$ mvn clean package jboss-as:deploy

之后的整个日志

我已经看到你可能需要在你的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中的内容。

Answer 1

正如您已经说过的，maven告诉您org.picketlink.distribution:picketlink-jbas7:jar:2.8.0.Beta1-SNAPSHOT依赖性缺失，我相信这是因为您之前没有安装它。

我可以看到jboss-picketlink-quickstarts是一组有父pom.xml的项目，您可以在其中找到您的项目作为模块：

<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。

这将引导您将所有需要解决的依赖项解析到本地maven存储库（通常为~/.m2/repository ）。

尝试一下，它会解决你的依赖。有时您必须使用-U调用maven来强制-SNAPSHOT依赖项。

希望它有所帮助！
