Jenkins Windows从站上的dotnet恢复-值不能为空

标签： c# jenkins .net-core nuget nuget-package-restore

我有一个.Net Core应用程序，正在尝试在我们的新Jenkins服务器上构建该应用程序，并且在还原NuGet软件包时遇到了问题。

我们的新构建基础结构由在CentOS上运行的Jenkins主文件组成，并且此特定构建在Windows Server 2012从服务器上运行。两者之间的连接是通过Cygwin的SSH进行的。

此版本可以在我们的旧版Jenkins上正常工作，该版本没有构建从属，并且可以在Windows Server 2012上运行。

我们正在使用Jenkinsfile调用NAnt构建目标来运行构建。这是NAnt构建文件中的还原目标：

<target name="restore_nuget_packages" description="Restores the NuGet packages for the solution" >
    <echo message="Restoring NuGet Packages" />
    <property name="USERPROFILE" value="${environment::get-variable('USERPROFILE')}" />
    <property name="HOME" value="${environment::get-variable('HOME')}" />
    <echo message="USERPROFILE is ${USERPROFILE}" />
    <echo message="HOME is ${HOME}" />
    <exec program="${dotnet_path}" commandline="restore ${projectName}.sln"></exec>
</target>

当此目标在我们的新服务器上运行时，我得到以下输出：

[NuGet Restore] BUILD FAILED

我发现了其他类似的问题：

https://github.com/dotnet/core/issues/1037#issuecomment-338315953 https://blog.jongallant.com/2017/12/dotnet-value-cannot-be-null-parameter-name-path1/ https://github.com/dotnet/cli/issues/2385

他们使我相信，分别对于Windows和Linux，USERPROFILE或HOME变量为null是一个问题。 dotnet将这些变量用于其NuGet程序包缓存，并且在构建％USERPROFILE％.nuget \ packages的路径时，Path.Combine（）方法会引发错误。

怀疑运行Linux的主服务器和运行Windows的从服务器可能存在问题，我尝试在构建节点本身上设置这两个变量（即使已经定义了USERPROFILE，我也确保明确设置了USERPROFILE） ，以及Jenkins UI中的构建节点环境变量配置。 las，我仍然遇到错误。我什至在目标输出的顶部添加了一些回显，并且您可以看到，这些变量的设置确实正确，但是dotnet restore命令仍然会引发错误。

关于我可能会缺少的任何建议吗？

1 个答案:

答案 0 :(得分：1)

我在-v diag通话中添加了dotnet。虽然输出非常冗长，但是它没有提供有关错误的更多信息（即哪个变量为null），但是我确实获得了堆栈跟踪，还有一些Googling使我想到了这一点：

.NET Core dotnet restore failing on jenkins with System.ArgumentNullException

我在Jenkins UI的从属环境变量配置中添加了LOCALAPPDATA变量，并对其进行了修复。

看来，dotnet，更具体地说是nuget cli，依靠几个Windows内置环境变量来构建路径，但是我在任何地方都找不到这些文档的列表。这是我们在Jenkins从站上定义的当前自定义变量的完整列表：

  • APPDATA
  • LOCALAPPDATA
  • TEMP
  • USERPROFILE

当然，这通常不是问题，因为它们应该始终存在于Windows系统上，但是在Jenkins从站上构建时，它会创建自己的自定义构建环境，并且您必须显式定义这些必需的内置变量你自己
