Hi Vincent,
We are using FinalBuilder7 version on our Build servers to build our applications. For example we are having multiple builds in a single Project.We are uisng MSBuild action to build but recently we are getting an error while building a Project in the middle (while building a particular build). The error message is like this “MSBuild.exe has stopped working” We had searched a lot regarding this but did not find any solution. This is highly impacting our automated build(Scheduled using Scheduler) as it is stopping in the middle.
Please find the attached error screen shot(msbuilderror.png) for this and also Error description below . Please help do needful…

Is there any log output in FinalBuilder for this action? Any other eventlog entries?

Check your environment variables.

Hi Vincent,
We are using the following path in the solution path of Msbuild action at which we are getting the above mentioned error (Unhandled Exception: Microsoft.Build.Shared.InternalErrorException: MSB0001: Internal MSBuild Error: Environment variable name or value is too long. )
Path we are using :
%ABCApplicationPath%%Release%\Site\Areas\members\Members.sln.
Here %ABCApplicationPath%=F:\ABCCode\_Automate\ABC\Releases
%Release%=Release\_14\_06
When we are building this we are gettting the error for first time after that we are stopping the Final builder solution and when tried to rebuild again from error point its working. We are not sure about this behaviour. Could you please help regardig this?Its affecting our automated builds.

You really haven’t given us anything to work with. What environment variables do you have, how long are you variables names in FinalBuilder, do you have any of those set to be exposed as Environment variables?

Actually we created Project variables while creating the variables we checked(checkbox) all the variables as(Make it as Environment variable). The below variables are project variable.
%ABCApplicationPath%%Release%\Site\Areas\members\Members.sln.
Here %ABCApplicationPath%=F:\ABCCode\_Automate\ABC\Releases
%Release%=Release\_14\_06
