# Execute GitVersion Task (gitversion/execute) Usage Examples
Find out how to use the **gitversion/execute** task using the examples below.
> The examples use the latest _0.x_ version of the GitVersion Execute task. It is recommended to use the latest released version in your own pipelines.
Note that if the pipeline is setup to use a shallow git fetch mode the GitVersion Execute task will fail. It is required to use fetchDepth of 0 like so:
```yaml
- checkout: self
fetchDepth: 0
```
## Inputs
The Execute GitVersion task accepts the following inputs:
```yaml
targetPath:
description: Optionally supply the path to the working directory.
required: false
default: ''
useConfigFile:
description: Whether to use a custom configuration file.
required: false
default: false
configFilePath:
description: Optional path to config file (defaults to GitVersion.yml).
required: false
default: ''
updateAssemblyInfo:
description: Whether to update versions in the AssemblyInfo files.
required: false
default: false
updateAssemblyInfoFilename:
description: Update versions in specified file.
required: false
default: ''
additionalArguments:
description: Additional arguments to send to GitVersion.
required: false
default: ''
```
## Outputs
The Execute GitVersion task creates the following job-scoped variables and multi-job output variables:
- GitVersion.Major
- GitVersion.Minor
- GitVersion.Patch
- GitVersion.PreReleaseTag
- GitVersion.PreReleaseTagWithDash
- GitVersion.PreReleaseLabel
- GitVersion.PreReleaseNumber
- GitVersion.WeightedPreReleaseNumber
- GitVersion.BuildMetaData
- GitVersion.BuildMetaDataPadded
- GitVersion.FullBuildMetaData
- GitVersion.MajorMinorPatch
- GitVersion.SemVer
- GitVersion.LegacySemVer
- GitVersion.LegacySemVerPadded
- GitVersion.AssemblySemVer
- GitVersion.AssemblySemFileVer
- GitVersion.FullSemVer
- GitVersion.InformationalVersion
- GitVersion.BranchName
- GitVersion.EscapedBranchName (since 5.2.0)
- GitVersion.Sha
- GitVersion.ShortSha
- GitVersion.NuGetVersionV2
- GitVersion.NuGetVersion
- GitVersion.NuGetPreReleaseTagV2
- GitVersion.NuGetPreReleaseTag
- GitVersion.VersionSourceSha
- GitVersion.CommitsSinceVersionSource
- GitVersion.CommitsSinceVersionSourcePadded (since 5.2.0)
- GitVersion.UncommittedChanges (since 5.5.0)
- GitVersion.CommitDate
The job-scoped variables can be accessed using the macro syntax `$(GitVersion.<variableName>)` in subsequent steps in the same job. Azure Pipelines also creates environment variables of the form `GITVERSION_<VARIABLENAME>`. See examples [5](#example-5) and [6](#example-6).
The multi-job output variables can be accessed across jobs and stages, in both conditions and variables. See examples [7](#example-7) to [10](#example-10).
**GitVersion also automatically updates the pre-defined Build variable `Build.BuildNumber`.**

## Examples
### Example 1
Calculate the version for the build.
```yaml
steps:
# gitversion/setup@0 task omitted for brevity.
- task: gitversion/execute@0
displayName: Determine Version
```
### Example 2
Calculate the version for the build using a config file with the default name **GitVersion.yml**.
```yaml
steps:
# gitversion/setup@0 task omitted for brevity.
- task: gitversion/execute@0
displayName: Determine Version
inputs:
useConfigFile: true
```
Example contents of **GitVersion.yml**:
```yaml
mode: Mainline
branches:
master:
regex: ^latest$
pull-request:
tag: pr
```
### Example 3
Calculate the version for the build using a config file named **VersionConfig.yml** in the root of the working folder.
```yaml
steps:
# gitversion/setup@0 task omitted for brevity.
- task: gitversion/execute@0
displayName: Determine Version
inputs:
useConfigFile: true
configFilePath: 'VersionConfig.yml'
```
### Example 4
Show the effective configuration for GitVersion by running the **/showConfig** command (passed as an additional argument).
```yaml
steps:
# gitversion/setup@0 task omitted for brevity.
- task: gitversion/execute@0
displayName: Display GitVersion config
inputs:
additionalArguments: '/showConfig'
```
### Example 5
Calculate the version for the build and display all the calculated variables in the next step.
```yaml
steps:
# gitversion/setup@0 task omitted for brevity.
- task: gitversion/execute@0
displayName: Determine Version

### Example 6

```yaml
steps:
# gitversion/setup@0 task omitted for brevity.
- task: gitversion/execute@0
displayName: Determine Version
- task: DotNetCoreCLI@2
displayName: Pack Example
inputs:
command: pack
packagesToPack: src/Example/LibExample.csproj
versioningScheme: byEnvVar
versionEnvVar: GitVersion.NuGetVersion # alternative syntax GITVERSION_NUGETVERSION (the former gets converted into the latter internally)
```
### Example 7
Calculate the version for the build and use the `GitVersion.BranchName` variable in a condition for starting another job.
```yaml
jobs:
- job: CalculateVersion
displayName: Calculate version using GitVersion
steps:
# gitversion/setup@0 task omitted for brevity.
- task: gitversion/execute@0
displayName: Use GitVersion
name: Version # the step MUST be named to access its output variables in another job.
- job: CreateReleaseNotes
condition: and(succeeded(), eq(dependencies.CalculateVersion.outputs['Version.GitVersion.BranchName'], 'main'))
dependsOn: CalculateVersion
```
### Example 8
Calculate the version for the build and map the `GitVersion.SemVer` variable into a variable in another job.
```yaml
jobs:
- job: CalculateVersion
displayName: Calculate version using GitVersion
steps:
# gitversion/setup@0 task omitted for brevity.
- task: gitversion/execute@0
displayName: Use GitVersion
name: Version # the step MUST be named to access its output variables in another job.
- job: BuildAndPack
variables:
Ver.MajorMinorPatch: $[ dependencies.CalculateVersion.outputs['Version.GitVersion.MajorMinorPatch'] ]
```
### Example 9
Calculate the version for the build and use the `GitVersion.Major` output variable in a condition for starting another stage.
```yaml
stages:
- stage: S1
jobs:
- job: CalculateVersion
displayName: Calculate version number using GitVersion
steps:
# gitversion/setup@0 task omitted for brevity.
- task: gitversion/execute@0
displayName: Use GitVersion
name: Version # the step MUST be named to access its output variables in another stage.
- stage: S2
condition: and(succeeded(), gt(dependencies.S1.outputs['CalculateVersion.Version.GitVersion.Major'], 0))
dependsOn: S1
```
### Example 10
Calculate the version for the build and map the `GitVersion.AssemblySemVer` variable into a variable in another job for a different stage.
```yaml
stages:
- stage: S1
jobs:
- job: CalculateVersion
displayName: Calculate version number using GitVersion
steps:
# gitversion/setup@0 task omitted for brevity.
- task: gitversion/execute@0

name: Version # the step MUST be named to access its output variables in another stage.
- stage: S2
dependsOn: S1
