From the docs, the variable Rev:.r
is the daily build revision count. The accepted "solution" would lead to one day finishing having a version of 1.0.12
, then the next day it will be 1.0.1
.
If you want a simple incremental and unique semver, use 1.0.$(BuildID)
.
$(BuildID)
is an internal immutable counter for your builds, and thus far cleaner than $(BuildNumber)
.
BuildID will always be incrementing - no reset.
Thus after a minor bump, you'd end up having say 1.2.123
becoming 1.3.124
.
If you want to perform this task well, this can be done using npm version or similar, such as pubspec_version for Dart or Flutter builds.
- script: npm version $RELEASE_TYPE
where $RELEASE_TYPE
is a variable you can set based on build (ie: CI, PR etc), having a value of major
, minor
, patch
, prerelease
etc.
- script: npm version $RELEASE_TYPE
condition: startsWith(variables['build.sourceBranch'], 'refs/head/release/')
env:
releaseType: minor
Update: Bump Repo Version and Use In Build (using npm)
To have the repo version update, I ended up including npm version as a DevDependency, with it's precommit hook to bump the project version on any commit.
This technique can be applied to other project types, placing them in a subfolder - although can lead to complications with server OS requirements.
To use this version in your build, add this bash script task, which gets and exports the version as a task variable:
v=`node -p "const p = require('./package.json'); p.version;"`
echo "##vso[task.setvariable variable=packageVersion]$v"
.Net Core Task only version
Unfortunately, no repo-bump.
jobs:
- job: versionJob #reads version number from the source file
steps:
- powershell: |
$fv = Get-Content versionFile
Write-Host ("##vso[task.setvariable variable=versionFromFile;isOutput=true]$fv")
displayName: 'version from file'
name: setVersionStep
- job: buildJob # consumes version number, calculates incremental number and set version using assemblyinfo.cs
dependsOn: versionJob
variables:
versionFromFile: $[ dependencies.versionJob.outputs['setVersionStep.versionFromFile'] ] # please note that spaces required between $[ and dependencies
buildIncrementalNumber: $[ counter(dependencies.versionJob.outputs['setVersionStep.versionFromFile'],1) ] #can't use $versionFromFile here
steps:
- powershell: |
Write-Host ($env:versionFromFile)
Write-Host ($env:versionFromFile + '.' + $env:buildIncrementalNumber)
displayName: 'version from file output'
This post describes a couple of others, using version-prefix and automatically applying the BuildNumber as a version-suffix.
