After 1st Build failure - keep getting InvalidOperationException

[Guest]

We've been running great with buildmaster for a few weeks. Today I pushed out a code with a bug, so we had our 1st build failure. I fixed the code, comitted to TFS, and forced a new build.
However now we keep getting this error:

Error

Done building project "CommonClassLib.csproj" -- FAILED.

Done building project "StPlatformWebRole.csproj" -- FAILED.
An unhandled exception occurred while executing this action: System.InvalidOperationException: There are no files in the expected output directory: C:\BuildMaster_SVCTMP_A3_S7\TMP\Debug\Package\PackageTmp at Inedo.BuildMaster.Extensibility.Actions.RemoteCommandExecution.RemoteCommandExecuter.ExecuteCommand(RemoteActionBase remoteAction, String commandName, String[] commandArgs) at Inedo.BuildMaster.Extensibility.Agents.Local.LocalAgent.Inedo.BuildMaster.Extensibility.Agents.IRemoteCommandExecuter.ExecuteCommand(RemoteActionBase action, String commandName, String[] commandArgs) at Inedo.BuildMaster.Extensibility.Actions.RemoteActionBase.ExecuteRemoteCommand(String name, String[] args) at Inedo.BuildMaster.Extensibility.Actions.ActionBase.ExecuteInternal(IActionExecutionContext context, ExtensionConfigurerBase extensionConfigurer, Boolean resumeNextOnError, Boolean logErrorsAsWarnings)

Can you include the full build log? It looks like CommonClassLib.csproj failed to build, which would cause the error you've posted.

Hey Tod,

Totally odd - but this is how I fixed it.

1. I added a few extra files into the web project, clicked an "included in project"
2. Due to this the .cproj file was changes (due to new files)
3. Commited all changes in SVN
4. waited 1 min, then started the build

bam! finally it succeeded. May have been some sort of "stale" proj file or something.
