Problems using MSBuild target in TFS build (Visual Studio Online hosted build controller)

May 11, 2014 at 4:10 PM

I'm trying to have JSLint execute as part of our TFS build using a Visual Studio Online hosted build controller. I added the build-target using the JSLint NuGet package. Locally the solution builds just fine using MSBuild in a command line correctly reporting the issues from JSLint, but the TFS build fails with the following error:

"C:\a\src\XXX\ProjectX\ProjectX.csproj" (default target) (8) ->

Does anyone else have seen this problem? It might very easy be that some environment difference triggers this error, but is it not possible to have some more details from Noesis in order to debug this problem?

Shame there isn't a more specific exception other than that the task failed unexpectedly.

Do you happen to know if it's running under x64 or x86 MSBuild? If it's not something to do with the bitness, then it's possible V8 can't find the bundled VCplusplus runtimes.

It may be possible to install those manually on the build machine.

Edit: Oh, and it might also be worth trying the beta. It doesn't use V8, but it does required IE9plus:

To be honest, I do not know whether it's running x64 or x86 of MSBuild, but I will investigate. Unfortunately it's not possible to install any software on the build controller (at least as long as we are using the hosted build controller) - the current specs are as in

In the meantime I've tried with 2.0.0-beta4, but then I get a NullReferenceException instead - is something missing on the build controller?

That's great information, thank you. I'll try to spin up a VM with similar specs and see if I can replicate the problem.

I've been been able to play a bit more with the build. Changing MSBuild to run as x86, then then it seems work with the 1.6.2 version! :) Ideally, I would like to continue with the default build settings ("Auto" which seems to imply x64), so is there anything that I could investigate why it's not working in the x64 environment?
Unfortunately the 2.0.0-beta4 fails with the same error (NullReferenceException). :(

That's very interesting, and should make replication easier. Will update with my findings once I've had a chance to look at it.

I've had a chance to do some research around this, and it seems like the x64 version of the Microsoft C runtime libraries can't be found. Normally they're already on a machine so the versions we bundle with JSLint.NET aren't used.

It's related to JavaScript.NET and it's use of V8. See the comments on redistribution here:

I've created an experimental version of JSLint.NET with the paths moved around a bit. I'm hoping this will allow the bundled versions of the Microsoft C runtime libraries to be located on your build server.

Would you mind testing out a custom NuGet package?
