缺少Azure WebJob中的dotnet.exe

Question

我正在尝试将.NET Core Console应用程序部署为Azure WebJob.所有文件等都被复制到正确的目录,但我的控制台应用程序的输出是.dll,所以它需要dotnet.exe启动.

我用单个命令添加了一个run.cmd文件:dotnet QbiSync.dll.但输出如下,似乎找不到dotnet.exe:

[11/14/2016 13:15:29 > 4741da: SYS INFO] Run script 'run.cmd' with script host - 'WindowsScriptHost'
[11/14/2016 13:15:29 > 4741da: SYS INFO] Status changed to Running
[11/14/2016 13:15:29 > 4741da: INFO] 
[11/14/2016 13:15:29 > 4741da: INFO] D:\local\Temp\jobs\continuous\QbiSync\x4jkoxww.vy4>dotnet QbiSync.dll 
[11/14/2016 13:15:29 > 4741da: ERR ] 'dotnet' is not recognized as an internal or external command,
[11/14/2016 13:15:29 > 4741da: ERR ] operable program or batch file.
[11/14/2016 13:15:29 > 4741da: SYS ERR ] Job failed due to exit code 1
[11/14/2016 13:15:29 > 4741da: SYS INFO] Process went down, waiting for 60 seconds

使用Kudu或在Azure门户中打开控制台窗口并调用dotnet.exe它们都可以正常工作.我也试过像这样的硬链接:

• "D:\Program Files (x86)\dotnet\dotnet.exe" QbiSync.dll
• "\Program Files (x86)\dotnet\dotnet.exe" QbiSync.dll

但他们也会给出如下错误:

[11/14/2016 13:59:29 > 4741da: ERR ] The filename, directory name, or volume label syntax is incorrect.
[11/14/2016 13:59:29 > 4741da: INFO] D:\local\Temp\jobs\continuous\QbiSync\hzlkzj1q.0jt>"D:\Program Files (x86)\dotnet\dotnet.exe" QbiSync.dll 

即使dotnet.exe实际上位于那里.

更新:

可能相关的是@echo off脚本开头使用的源代码.但这也是一个似乎不被接受的"命令".

[11/14/2016 12:37:57 > 4741da: INFO] D:\local\Temp\jobs\continuous\QbiSync\3n44nly1.ucq>@echo off

问题是您run.cmd使用带有BOM(字节顺序标记)的UTF-8 ,这在某些情况下会导致脚本引擎行为异常.修复是没有BOM.

wiki(https://github.com/projectkudu/kudu/wiki/Web-Jobs)上提到了这一点,但很容易让人错过.
