Troubleshooting OctoPack

Last updated

Sometimes OctoPack doesn't work the way you expected it to, or perhaps you are having trouble configuring your .nuspec file. Here are some steps to help you diagnose what is going wrong, and fix the problem.

  1. Run the build in your local development environment using the Visual Studio developer command prompt using arguments something like this:
msbuild MySolution.sln /t:Build /p:Configuration=Release /p:RunOctoPack=true /fl

The /p:RunOctoPack=true argument configures OctoPack to run as part of the build process The /fl argument configures msbuild.exe to write the output to a log file which will usually look like msbuild.log. Refer to the MSBuild documentation for more details. Note: You may need to change some of these parameters to match the process you are using on your build server. Take a look at the build server logs and try to emulate the process as closely as possible.

  1. Inspect the MSBuild output log file. If OctoPack has executed successfully you should see log entries like the ones shown below generated using OctoPack 3.0.42:

  • If you cannot see any OctoPack-related log messages, perhaps OctoPack isn't installed into your project(s) correctly?
    • Try completely uninstalling OctoPack and installing it again.
    • Check inside your .csproj or .vbproj file for an include statement like the following example:
<Import Project="..\packages\OctoPack.3.0.42\tools\OctoPack.targets" Condition="Exists('..\packages\OctoPack.3.0.42\tools\OctoPack.targets')" />
  • If OctoPack is running but your files are not being packed correctly, see if the file is mentioned in the build log.
    • Files that are copied to the build output directory will be included in the package. Take a look at the contents of your build output directory and compare that with the messages in the build log.
    • For web applications, files that are configured with the Visual Studio property Build Action: Content will be included in the package.
    • If you have specified the <files> element in a custom .nuspec file, perhaps you need to add the /p:OctoPackEnforceAddingFiles=true MSBuild argument as discussed above?
    • If you have specified the <files> element in a custom .nuspec file, perhaps you need to experiment with some different combinations of include and exclude?
