Plugins?

[Ciberusps]

Runned workflow without plugin - all works fine

Cloned my plugin to "Plugins" folder and get error

"Error: Plugin 'UnrealHelperLibrary' failed to load because module 'UnrealHelperLibrary' could not be found.  Please ensure the plugin is properly installed, otherwise consider disabling the plugin for this project"

Tried to run checkouted project by hands

And all works fine project runs after "Yes" in this window

Looks like plugins should be build with UAT before building project?

The only time I ran into that issue was when my Github runner was failing to properly clone my submodules (in my case, plugins) into my project. Here are the first steps that I use on a build:

jobs:
  build:
    runs-on: self-hosted
    environment: ${{ 
        (github.ref == 'refs/heads/dev' && 'Development') || 
        (github.event_name == 'release' && startsWith(github.ref, 'refs/tags/') && contains(github.ref, '-alpha') && 'Staging') || 
        (github.event_name == 'release' && startsWith(github.ref, 'refs/tags/') && contains(github.ref, '-beta') && 'Staging') || 
        (github.event_name == 'release' && startsWith(github.ref, 'refs/tags/') && contains(github.ref, '-rc') && 'Staging') || 
        (github.event_name == 'release' && startsWith(github.ref, 'refs/tags/') && 'Production') || 
        'Development' 
      }}
    steps:
    - name: Checkout Repository
      uses: actions/checkout@v2
      with:
        token: ${{ secrets.ACCESS_TOKEN }}
        lfs: true
        fetch-depth: 0 # Fetches all history for all tags and branches
        submodules: recursive

    - name: Checkout LFS Objects
      run: git lfs checkout

I will test with Unreal Helper Library myself later to try and trace the issue.

Do you store your plugins compiled with "Intermediate"/"DerivedDataCache"/"Saved"?

[Ciberusps]

Its important to note that I use "Blueprint" project, it builds fine without plugin(s)

UPD my github-action setup

Do you store your plugins compiled with "Intermediate"/"DerivedDataCache"/"Saved"?

No I typically keep each plugin in it's own repository as source and then submodule them in to my projects as needed. I have never had any plugin compilation issues. Here is where I run this in my workflow:

    - name: Cook, Stage & Package UE Project
      uses: OrchidIsle/UE5-Build-Project@latest
      with:
        RUNUAT_PATH: ${{ env.RUNUAT_PATH }}
        UPROJECT_PATH: ${{ github.workspace }}\MyProject\MyProject.uproject
        BUILD_CONFIG: ${{ vars.BUILD_CONFIG }}
        PLATFORM: Win64
        COOK: true
        STAGE: true
        PACKAGE: true
        PAK: true
        SERVER: false
        EDITOR: true
        ENCRYPT_INI: true
        DELETE_PDB: ${{ github.event_name == 'release' }}
        ANTICHEAT_ENABLED: true
        ANTICHEAT_PRIVATE_KEY: ${{ secrets.ANTICHEAT_PRIVATE_KEY }}
        ANTICHEAT_PUBLIC_CERT: ${{ secrets.ANTICHEAT_PUBLIC_CERT }}

    - name: Compress Win64 Client using 7-Zip
      run: |
        $7zPath = "${{ env.SEVEN_Z_PATH }}"
        $sourceDir = "${{ github.workspace }}\MyProject\Saved\StagedBuilds\Windows"
        $archiveFile = "MyProject-Win64-${{ env.BUILD_ID }}.zip"
        & "$7zPath" a -tzip "$archiveFile" "$sourceDir\*"

    - name: Copy to Archive
      run: |
        $sourcePath = "MyProject-Win64-${{ env.BUILD_ID }}.zip"
        $destinationPath = "${{ env.ARCHIVE_PATH }}\Builds\Win64\MyProject-Win64-${{ env.BUILD_ID }}.zip"
        $destinationDirectory = Split-Path -Path $destinationPath -Parent
    
        if (-not (Test-Path -Path $destinationDirectory)) {
            New-Item -ItemType Directory -Path $destinationDirectory
        }
    
        Copy-Item -Path $sourcePath -Destination $destinationPath

I will give it a shot with Blueprint and UnrealHelperLibrary later.

[Ciberusps]

Not sure but looks like I found why I get Error: Plugin 'UnrealHelperLibrary' failed to load because module 'UnrealHelperLibrary' could not be found

This morning I received feedback from FAB on my submission of UHL to FAB, so they say that plugin not compiles, but I sure that it compiles in several projects in my studio and with production builds works fine. Looks like they use RunUAT for building plugins and building plugin via RunUAT gives same errors as FAB sended in feedback. RunUAT BuildPlugin gives somehow more errors than default build, probably RunUAT for projects internally builds plugins via RunUAT BuildPlugin if no binaries found. Thats why I get this error - I need to fix build errors in RunUAT BuildPlugin

Looks like that't not an issue in UE5-Build-Project. But if you want you can optionally improve such errors handling by looking in output of RunUAT and if it says that "Error: Plugin N failed to load" throw more clean error/addition Probably plugin not compiles right, try build it using "RunUAT BuildPlugin" https://dev.epicgames.com/community/learning/tutorials/qz93/unreal-engine-building-plugins

I'll test if it works after fixes and will text you here
