Travis-CI failure with .NET Core

Hi,

You may remember me as the person who asked for .NET Core support. I finally got around to unit-testing my game and decided to add Travis-CI integration.

TL;DR it failed with something related to MonoGame. Can you please tell me if/what I’m doing wrong? It looks like it’s failing to build the project.

The core error appears to be:

/home/travis/.nuget/packages/monogame.content.builder/3.7.0.4/build/MonoGame.Content.Builder.targets(27,5): error MSB4018: The "GetMGCBTask" task failed unexpectedly.

Travis log here.

Travis configuration:

language: csharp
solution: escape-to-earth.sln
mono: none
dotnet: 2.2.200
script:
  cd EscapeToEarth.UnitTests
dotnet test

Project repository lives here. I can build this locally and run tests on Windows 8/10.

I don’t know. Travis workspaces are still a mystery to me (I don’t know how to view/save files on disk).

Instead, I did some googling on how to get MonoGame projects to build on Travis. I found this wonderful answer; the summary is that I added these changes to my .travis.yml file:

before_install:
  - wget http://www.monogame.net/releases/v3.4/MonoGame.Linux.zip
  - unzip MonoGame.Linux.zip
  - find * -type f -exec chmod 777 {} \; # lazy just make all executable
install:
  - sudo apt-get install -qq monodevelop libopenal-dev ttf-mscorefonts-installer gtk-sharp2; # install needed packages for the monogame sdk
  - sudo ./generate.sh && yes Y|sudo ./monogame-linux.run; # install monogame sdk

(This is a slightly modified version because one of the packages, erm, I think it doesn’t exist in the version of Linux that the Travis docker container is using.)

This resulted in a successful build, so I’m good to go now. Thanks for your help.

Nope, SadConsole just loads direct PNG files and doesn’t use the pipeline. I just looked up linux exit code 127 and it says that it really means file not found. https://stackoverflow.com/questions/1763156/127-return-code-from

Does /home/travis/.nuget/packages/monogame.content.builder/3.7.0.4/build/MGCB/build/MGCB.exe exist?
