We're getting an error from TravisCI trying to build an open source library:
You can view the error here:
Your other forums said to report a bug here,
The error is:
../Baseclass.Contrib.Nuget.Output.2.1.0/build/net40/Baseclass.Contrib.Nuget.Output.targets (CollectNugetOutputFiles target) -> error : Error initializing task PackageFilter: Not registered task PackageFilter.
THe forum theory is that "Baseclass.Contrib.Nuget.Output" is using msbuild trickery that isnt in xbuild.
Import Project="..\packages\Baseclass.Contrib.Nuget.Output.2.1.0\build\net40\Baseclass.Contrib.Nuget.Output.targets" Condition="Exists('..\packages\Baseclass.Contrib.Nuget.Output.2.1.0\build\net40\Baseclass.Contrib.Nuget.Output.targets')"
We can't remove it from our project. I'm hoping you have a fix or work around we can use.
We deprecated xbuild and recommend using msbuild instead. Switching to msbuild will also most likely resolve the issue you reported.
