.Net framework assemblies in BitBucket pipelines

Hi everyone,

I'm trying to build our .Net application in Bitbucket pipelines. We want to target the .Net framework 4.5.2.

Here is my project.json file:

    "name": "MyProjectName",
    "frameworks": { 
        "net452": {
            "frameworkAssemblies": {
                "System.ComponentModel.DataAnnotations": "",
                "System.Data": "",
                "System.Web": "",

If I use the dotnet build command on my machine, it works well. But in Pipelines, I get this message:

"error DOTNET1012: The reference assemblies directory was not specified. You can set the location using the DOTNET_REFERENCE_ASSEMBLIES_PATH environment variable."

Is it possible to build .Net projects with framework assemblies? And if yes, what changes should I do?

Thanks in advance.

Hey Andreas,

It looks like this is a result of incompatibilities with .NET and docker. For more information on running .NET with pipelines check http://davevde.github.io/using-bitbucket-pipelines-with-aspnet-core/ and https://blog.maartenballiauw.be/post/2016/08/17/building-nuget-netcore-using-atlassian-bitbucket-pipelines.html.

Hi Thomas,

My application cannot be compiled with .NET Core, so I won't be able to use Pipelines for my project. I tried with a smaller one and it worked.

I will wait for .NET Core development then, thanks for the help!

Hey Andreas,

Because pipelines uses Docker to build your branch it uses Linux and therefore can only use .NET Core. Have you tried running your build using .NET Core? Have you tried running it using the docker image you have set up on pipelines?

Hi Thomas,

Thanks for your answer.

I tried building the application on the docker image and indeed it fails there as well.

I will see if I can build locally before reusing Pipelines.
