MSBuild中的电子邮件错误 - ReadLinesFromFile“被另一个进程” [英] Email Errors in MSBuild - ReadLinesFromFile "is being used by another process"

问题描述

我正在尝试从这里实现答案：
如何访问MSBuild中的错误详细信息

 > msbuild MyProject.proj / fl /flp:v=detailed;logfile=mylog.txt 
 
<目标名称=ErrorEmail> 
< ReadLinesFromFile 
 File =mylog.txt
 Lines =_ ErrorLines
 /> 
< Mail 
 SmtpServer =mysrv
 From =me @ mysrv
 To =error @ mysrv
主题=发生错误
 Body =错误详细信息：@（_ ErrorLines，'％0D％0A'）
 /> 
< / Target> 
  

看起来很优雅，但我收到这个错误：

c：\AccuRev\Build_2012_01_02\MyApp\ErrorHandlers.targets（24,9）：
错误MSB3501：无法从文件mylog中读取行。文本。
进程无法访问文件
'c：\AccuRev\Build_2012_01_02\MyApp\mylog.txt'，因为
正在被另一个进程使用

解决方案

mylog.txt文件被锁定，因为您正在为构建日志和ReadLinesFromFile任务使用相同的文件。 / p>

编辑：尝试执行MSBuild 2次。首先建立你的项目和第二次发送电子邮件。使用/flp1:logfile=errors.txt使用 distributedFileLogger 命令行开关; erroronly命令行参数将所有错误记录到errors.txt。然后，您可以将此文件附加到您的电子邮件中，而无需发送整个构建日志。

I'm trying to implement the answer from here: How to access error details in MSBuild

> msbuild MyProject.proj /fl /flp:v=detailed;logfile=mylog.txt

<Target Name="ErrorEmail">
   <ReadLinesFromFile
      File="mylog.txt"
      Lines="_ErrorLines"
      />
   <Mail
      SmtpServer="mysrv"
      From="me@mysrv"
      To="error@mysrv"
      Subject="An error occured"
      Body="Error details: @(_ErrorLines, '%0D%0A')"
      />
</Target>

Looks elegant, but I'm getting this error:

c:\AccuRev\Build_2012_01_02\MyApp\ErrorHandlers.targets(24,9): error MSB3501: Could not read lines from file "mylog.txt". The process cannot access the file 'c:\AccuRev\Build_2012_01_02\MyApp\mylog.txt' because it is being used by another process

解决方案

mylog.txt file is locked because you are using the same file for build log and for the ReadLinesFromFile task.

EDIT: Try to execute MSBuild 2 times. First to build your projects and 2nd time to send an email. Use distributedFileLogger command line switch with /flp1:logfile=errors.txt;errorsonly command line parameters to log all errors to errors.txt. You can then attach this file into your email without sending whole build log.
