MSBUILD : Logger error MSB4104: Failed to write to log file Intermittent Issue RRS feed

  • Question

  • Hi Team,

    We are using Azure Devops for our CI pipelines .We are using the Ms Build task to build the solution file with Create log file enabled. recently we have noticed following ms build errors sporadically. the Agent has all the Required Administrative permissions on the build server.And also excluded the agent folders as part of the scanning also.


    Error Message:

    MS BUILD : Logger error MSB4104: Failed to write to log file "E:\VstsAgent01\_work\374\s\***.sln.log". The process cannot access the file 'E:\VstsAgent01\_work\374\s\***.sln.log' because it is being used by another process.
    ##[error]Process 'msbuild.exe' exited with code '1'.

    MSBuild Task Details:

    Task         : MSBuild
    Description  : Build with MSBuild
    Version      : 1.151.0

    Agent Version: 2.133.3

  • Hi friend,

    Thanks for posting here.

    This forum is about the MSBuild locally in VS(Discuss the Microsoft build engine aka MSBuild. Topics including: usage of MSBuild, build customization, and MSBuild extensibility via tasks, loggers and hosting). 

    As your issue is more related to the Devops, I suggest that you could open an new thread on the DeveloperCommunity or Stack OverFlow with Devops tag for better support.

    If you have some MSBuild questions, please feel free to contact us. We will try our best to give you a solution.

    Thanks for your understanding and cooperation. 

    Best Regards
