AppHarbor build error with nuget packages

Question

I'm getting a build error when deploying to AppHarbor from bitbucket. It's related to one of the projects not being able to resolve a dependency which should come from Nuget. Everything builds and runs fine on my machine. Knowledge - I am very well versed with Nuget and an experienced dev. I probably caused this by shuffling folders around locally and recreating the bitbucket repo. I've checked the bitbucket source and it seems everything is there compared to local.

My solution is structured similar to this:

\repo\app.sln
\repo\model\model.csproj
\repo\web\web.csproj

model is a core/models class library project. web is a web application (webapi2 + html) which takes a dependency on model. Both build correctly and run fine on my local box, but I recently had some issues with Bitbucket so I moved stuff around on disk and created a new repository. This broke the build only when it gets shipped up to Appharbor.

Nuget package restore is turned on for both projects.

Here's the top of the log from AppHarbor build process:

                 For SearchPath "{HintPathFromItem}".

As you can see the "model" (#4) project is unable to resolve references for the MongoRepository nuget package. That cascades and breaks the build.

Here's the packages.config for the model proj:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="mongocsharpdriver" version="1.8.3" targetFramework="net45" />
  <package id="MongoRepository" version="1.6.3" targetFramework="net45" />
</packages>
Was it helpful?

Solution 2

There were some paths in the csproj that were broken:

  <ItemGroup>
    <Reference Include="MongoDB.Bson">
      <HintPath>..\web\packages\mongocsharpdriver.1.8.3\lib\net35\MongoDB.Bson.dll</HintPath>
    </Reference>
    <Reference Include="MongoDB.Driver">
      <HintPath>..\web\packages\mongocsharpdriver.1.8.3\lib\net35\MongoDB.Driver.dll</HintPath>
    </Reference>
    <Reference Include="MongoRepository.Net45, Version=1.6.2.0, Culture=neutral, processorArchitecture=MSIL">
      <SpecificVersion>False</SpecificVersion>
      <HintPath>..\packages\MongoRepository.1.6.3\lib\net45\MongoRepository.Net45.dll</HintPath>
    </Reference>
    <Reference Include="System" />
    <Reference Include="System.Core" />
    <Reference Include="System.Xml.Linq" />
    <Reference Include="System.Data.DataSetExtensions" />
    <Reference Include="Microsoft.CSharp" />
    <Reference Include="System.Data" />
    <Reference Include="System.Xml" />
  </ItemGroup>

Needed to change the HintPath to ..\packages to remove the web directory.

OTHER TIPS

Changing the HintPath to ..\packages didn't work for me but changing it to $(Solutiondir)\packages worked for me like a charm.
