sbt 无法下载 jna-4.1.0.jar 连接重置

Question

我有一个带有现有 Play/Scala 项目的新 SBT/Scala 设置。当我尝试在文件夹中运行 activator clean 时，出现以下错误：

如果我尝试将 jar 的 URL https://repo1.maven.org/maven2/net/java/dev/jna/jna/4.1.0/jna-4.1.0.jar 粘贴到浏览器中，我就可以下载该 jar。 我尝试删除 .sbt 和 .ivy 文件夹，然后再次运行该命令，但得到了同样的错误。

不确定发生了什么？

提前致谢。

更新 我从激活器 UI 运行构建并启用调试输出。这是我发现的：

Activator首先尝试下载https://repo.typesafe.com/typesafe/ivy-releases/net.java.dev.jna/jna/4.1.0/jars/jna.jar

这真的不存在。将网址复制并粘贴到浏览器中，它显示未找到。

然后它尝试https://repo.scala-sbt.org/scalasbt/sbt-plugin-releases/net.java.dev.jna/jna/4.1.0/jars/jna.jar 并由于同样的原因失败。

然后它尝试https://repo1.maven.org/maven2/net/java/dev/jna/jna/4.1.0/jna-4.1.0.jar 成功并开始下载，但失败并出现以下错误：

不确定是什么导致了connection reset？

更新 2： 原来有问题的 jar 中有一个 DLL 文件。我想知道是否是导致问题的 Netscaler/Antivirus。已记录与网络管理员的通话。

Answer 1

我可以得到您没有将Local Maven Repository 设置为您的存储库之一的信息，这意味着您的 sbt 项目将不会在本地 maven 存储库中搜索依赖项，该存储库是存储您的 maven 依赖项 jar 的地方。如果您的 sbt 项目无法自行从 Internet 下载 jar。您可以通过以下方式提供帮助：

首先，在你的 build.sbt 中添加以下语句

resolvers += ("Local Maven Repository" at "file:///"+Path.userHome.absolutePath+"/.m2/repository")

其次，自己从maven仓库下载依赖jar。至于你的问题，下载链接是there

然后，假设 jar 文件位于目录 ~ 中，使用以下命令将 jar 发布到本地 maven 存储库

mvn install:install-file -Dfile=~/jna-4.1.0.jar -DgroupId=net.java.dev.jna -DartifactId=jna -Dversion=4.1.0 -Dpackaging=jar

最后，刷新你的 sbt 项目。

如果你找到mvn command not found，请安装它。

reference 我对另一个问题的回答可能会对您有所帮助。

祝你好运
