Jenkins Windows slave 上的 dotnet restore - 值不能为空
dotnet restore on Jenkins Windows slave - Value cannot be null
我有一个 .Net Core 应用程序，我正在尝试在我们的新 Jenkins 服务器上构建它，并且 运行 正在解决恢复 NuGet 包的问题。
我们新的构建基础设施包括一个在 CentOS 上的 Jenkins master 运行ning，这个特定的构建是 运行 在 Windows Server 2012 slave 上。两者之间的连接是通过 Cygwin 的 SSH。
这个构建在我们的旧 Jenkins 上工作得很好，它没有构建从属，运行s 在 Windows Server 2012 上。
我们正在使用 Jenkinsfile 将 NAnt 构建目标调用到 运行 构建。这是来自 NAnt 构建文件的恢复目标：
<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>
当这个目标 运行 在我们的新服务器上时，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
他们让我相信这是一个问题，USERPROFILE 或 HOME 变量为空，分别是 Windows 和 Linux。 dotnet 将这些变量用于其 NuGet 包缓存，并且 Path.Combine() 方法在构建到 %USERPROFILE%.nuget\packages.
的路径时抛出错误
怀疑可能是master 运行ning Linux和slave 运行ning Windows的问题，我尝试在构建节点本身（我确保明确设置 USERPROFILE，即使它已经被定义），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包含了一些回声，如您所见，这些变量确实设置正确，但 dotnet restore 命令仍然抛出错误。
对我可能遗漏的内容有什么建议吗？
我在 dotnet 调用中添加了 -v diag。虽然输出非常冗长，但它没有提供更多关于错误的信息（即哪个变量为空），但我确实得到了堆栈跟踪，一些额外的谷歌搜索让我找到了这个：
.NET Core dotnet restore failing on jenkins with System.ArgumentNullException
我将 LOCALAPPDATA 变量添加到 Jenkins UI 的从环境变量配置中，然后修复了它。
似乎 dotnet，更具体地说是 nuget cli，依赖于几个 Windows 内置环境变量来构建路径，但我无法在任何地方找到这些记录的列表。这是我们在 Jenkins slave 上定义的自定义变量的当前完整列表：
- 应用数据
- 本地应用程序数据
- 温度
- 用户个人资料
当然，这通常不是问题，因为这些应该始终存在于 Windows 系统中，但是在 Jenkins 从站上构建时，它会创建自己的自定义构建环境，您必须明确定义这些需要你自己的内置变量。
我有一个 .Net Core 应用程序，我正在尝试在我们的新 Jenkins 服务器上构建它，并且 运行 正在解决恢复 NuGet 包的问题。
我们新的构建基础设施包括一个在 CentOS 上的 Jenkins master 运行ning，这个特定的构建是 运行 在 Windows Server 2012 slave 上。两者之间的连接是通过 Cygwin 的 SSH。
这个构建在我们的旧 Jenkins 上工作得很好，它没有构建从属，运行s 在 Windows Server 2012 上。
我们正在使用 Jenkinsfile 将 NAnt 构建目标调用到 运行 构建。这是来自 NAnt 构建文件的恢复目标：

[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
他们让我相信这是一个问题，USERPROFILE 或 HOME 变量为空，分别是 Windows 和 Linux。 dotnet 将这些变量用于其 NuGet 包缓存，并且 Path.Combine() 方法在构建到 %USERPROFILE%.nuget\packages.
的路径时抛出错误怀疑可能是master 运行ning Linux和slave 运行ning Windows的问题，我尝试在构建节点本身（我确保明确设置 USERPROFILE，即使它已经被定义），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包含了一些回声，如您所见，这些变量确实设置正确，但 dotnet restore 命令仍然抛出错误。
对我可能遗漏的内容有什么建议吗？
我在 dotnet 调用中添加了 -v diag。虽然输出非常冗长，但它没有提供更多关于错误的信息（即哪个变量为空），但我确实得到了堆栈跟踪，一些额外的谷歌搜索让我找到了这个：
.NET Core dotnet restore failing on jenkins with System.ArgumentNullException
我将 LOCALAPPDATA 变量添加到 Jenkins UI 的从环境变量配置中，然后修复了它。
似乎 dotnet，更具体地说是 nuget cli，依赖于几个 Windows 内置环境变量来构建路径，但我无法在任何地方找到这些记录的列表。这是我们在 Jenkins slave 上定义的自定义变量的当前完整列表：
- 应用数据
- 本地应用程序数据
- 温度
- 用户个人资料
当然，这通常不是问题，因为这些应该始终存在于 Windows 系统中，但是在 Jenkins 从站上构建时，它会创建自己的自定义构建环境，您必须明确定义这些需要你自己的内置变量。
