The specified task executable "csc.exe" could not be run. Access is denied

Question

Hi,

I'm trying to build a small .Net solution (17 projects) but the build is failing with

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.CSharp.targets(316,9): error MSB6003: The specified task executable "csc.exe" could not be run. Access is denied [Path to Web Project]

Standard libraries are building fine it's just the 4 web projects that are failing.

Has anyone else seen this type of error before? I'm looking at creating my own custom image as it looks like the bamboo user on the elastic box doesn't have the correct permissions.

Thanks

Hi Rafael,

I'm using Bamboo Cloud with the standard elastic EC2 agents. I managed to fix the issue by adding the script below immediately after checking out the source code:

takeown /r /d y /f .
icacls . /t /grant Bamboo:F

It seems that the Bamboo user on the machine doesn't have the correct permissions on the build folder.

Regards,
Warren

Hello Warren

Thank you for your question.

Are you running Bamboo Cloud or Bamboo behind the firewall?

Are you running the build in the same box where Bamboo server is running? Or on a Remote agent? Or EC2 agent?

Are you running Bamboo as a Windows Service?

What is the full path to "csc.exe" in the box where the build is running?

Are you able top run the build manually by visiting the "Build Working Directory" in a Command Prompt run your MSBuild?
