scala – 首次使用SBT – 检索代理后面的依赖项

2019年7月2日 365次阅读

我已经下载了SBT(sbt-0.13.15.zip)并将其解压缩,但是在运行sbt.bat时我遇到了问题.

最初,当我发现我需要仅指定https配置而不是http配置时,我修复了代理问题 – 当提供两者时,它正在接受http,并且它失败了.

所以现在我不再有代理问题了,但是在尝试获取jansi依赖项时它失败了：

它试图从存在的https://repo1.maven.org/maven2/org/fusesource/jansi/jansi/1.11/jansi-1.11.pom中获取数据,但它似乎无法解析它或其他东西(StringTokenizer抛出的NoSuchElementException).我试图将pom和jar文件放在它试图找到它们的本地：它找到但它们最终没有太大的区别.

类似的东西发生在typesafe-ivy-releases和sbt-ivy-snapshots上,为此它试图从不存在的远程URL获取一些常春藤信息：

> https://repo.typesafe.com/typesafe/ivy-releases/org.fusesource.jansi/jansi/1.11/ivys/ivy.xml
> https://repo.scala-sbt.org/scalasbt/ivy-snapshots/org.fusesource.jansi/jansi/1.11/ivys/ivy.xml

因此,在这种情况下,它失败并不是一个重大的惊喜.

什么可能是错的？

谢谢

我在这里看到https://github.com/typesafehub/activator/issues/18,它可能是Ipv4 / Ipv6的一个问题.我尝试添加推荐的属性以强制IPv4(-Djava.net.preferIPv4Stack = true),但它仍然无效.

但是,我觉得根本原因可能是这样的,或者某些编码问题,使得远程文件“不可解析”

昨天我花了整整一天手动获取依赖项,最后它还没有工作..然后我在家里试了一台没有代理的计算机,它运行得很好.所以现在我再次尝试,专注于运行sbt.bat：我在java调用之前在sbt.bat中添加了一个“echo”,以确保它符合我的预期,并且它确实：

"C:\Toolbox\apps\jdk\jdk1.8.0_25-windows-x64\bin\java.exe" -Dhttps.proxyHost=theProxyURL 
-Dhttps.proxyPort=8080 -Dhttps.proxyUser=myId -Dhttps.proxyPassword=myPassword
-cp "C:\Toolbox\apps\sbt-0.13.15_2ndTry\bin\sbt-launch.jar" xsbt.boot.Boot

但我仍然遇到问题..如果是证书问题或类似问题,我应该得到更明确的信息,对吧？

我观察到的是,即使代理配置不正确,我们也不会在日志中收到任何相关消息.例如,通过故意提供不正确的代理设置(例如,不存在的代理主机),我们得到的消息与配置正确的值时不同.这使得调试非常不方便.

另一个我发现,即使正确配置密码,当密码包含感叹号时,修改后的版本也可能会传递给SBT启动器.我为此创建了一个问题：https://github.com/sbt/sbt/issues/3139.但即使解决了这个问题,我仍然面临着问题.

实际上有几个代理相关的未决问题：https://github.com/sbt/sbt/issues?utf8=%E2%9C%93&q=is%3Aissue%20is%3Aopen%20proxy

我现在要注意的一件事是配置代理存储库：http://www.scala-sbt.org/0.13/docs/Proxy-Repositories.html(我们使用Nexus)

最佳答案即使我无法找到我最初问题的确切答案,我也学到了一些东西：

>在企业互联网代理后面使用SBT的解决方法是使用内部Nexus代理：Why is sbt trying to download non-existing dependencies?
> SBT日志记录不是很有帮助,相同的错误消息可能有几十个失败的实际原因.
>根据配置的依赖性存储库(http://www.scala-sbt.org/0.13/docs/Proxy-Repositories.html),SBT将根据各种命名约定(Ivy和Maven)尝试各种UR.这就是有时URL根本不存在的原因.
