My repository in my organisation's devops project contains a lot of .net solutions and some unity projects as well. When I run my build pipeline, it fails due to several of these:
Error MSB3491: Could not write lines to file "obj\Release\path\to\file". There is not enough space on the disk.
I would like the pipeline to only checkout and fetch parts of the repository that are required for a successful build. This might also help with execution time of the pipeline since it currently also fetches the whole of my unity projects with gigabytes of resources which takes forever.
I would like to spread my projects across multiple repositories but the admin won't give me more than the one I already have. It got a lot better when I configured git fetch as shallow (--depth=1) but I still get the error every now and then.
This is how I configured the checkout:
steps:
- checkout: self
clean: true
# shallow fetch
fetchDepth: 1
lfs: false
submodules: false
The build is done using VSBuild@1 task.
I can't find a valid solution to my problem except for using multiple repositories, which is not an option right now.
Edit: Shayki Abramczyk's solution #1 works perfectly. Here is my full implementation.
GitSparseCheckout.yml:
parameters:
access: ''
repository: ''
sourcePath: ''
steps:
- checkout: none
- task: CmdLine@2
inputs:
script: |
ECHO ##[command] git init
git init
ECHO ##[command] git sparse-checkout: ${{ parameters.sourcePath }}
git config core.sparsecheckout true
echo ${{ parameters.sourcePath }} >> .git/info/sparse-checkout
ECHO ##[command] git remote add origin https://${{ parameters.repository }}
git remote add origin https://${{ parameters.access }}@${{ parameters.repository }}
ECHO ##[command] git fetch --progress --verbose --depth=1 origin master
git fetch --progress --verbose --depth=1 origin master
ECHO ##[command] git pull --progress --verbose origin master
git pull --progress --verbose origin master
Checkout is called like this (where template path has to be adjusted):
- template: ../steps/GitSparseCheckout.yml
parameters:
access: anything:<YOUR_PERSONAL_ACCESS_TOKEN>
repository: dev.azure.com/organisation/project/_git/repository
sourcePath: path/to/files/
In Azure DevOps you don't have option to get only part of the repository, but there is a workaround: Disable the "Get sources" step and get only the source you want by manually executing the according git commands in a script.
To disable the default "Get Sources" just specify none in the checkout statement:
- checkout: none
In the pipeline add a CMD/PowerShell task to get the sources manually with one of the following 2 options:
1. Get only part of the repo with git sparse-checkout.
For example, get only the directories src_1 and src_2 within the test folder (lines starting with REM ### are just the usual batch comments):
- script: |
REM ### this will create a 'root' directory for your repo and cd into it
mkdir myRepo
cd myRepo
REM ### initialize Git in the current directory
git init
REM ### set Git sparsecheckout to TRUE
git config core.sparsecheckout true
REM ### write the directories that you want to pull to the .git/info/sparse-checkout file (without the root directory)
REM ### you can add multiple directories with multiple lines
echo test/src_1/ >> .git/info/sparse-checkout
echo test/src_2/ >> .git/info/sparse-checkout
REM ### fetch the remote repo using your access token
git remote add -f origin https://your.access.token@path.to.your/repo
REM ### pull the files from the source branch of this build, using the build-in Azure DevOps variable for the branch name
git pull origin $(Build.SourceBranch)
displayName: 'Get only test/src_1 & test/src_2 directories instead of entire repository'
Now in the builds task make myRepo the working directory.
Fetching the remote repo using an access token is necessary, since using checkout: none will prevent your login credentials from being used.
In the end of the pipeline you may want to add step to clean the myRepo directory.
2. Get parts of the repo with Azure DevOps Rest API (Git - Items - Get Items Batch).
