build.ps1

<#
.SYNOPSIS
    Runs a .NET flavoured build process.
.DESCRIPTION
    This script was scaffolded using a template from the Endjin.RecommendedPractices.Build PowerShell module.
    It uses the InvokeBuild module to orchestrate an opinonated software build process for .NET solutions.
.EXAMPLE
    PS C:\> ./build.ps1
    Downloads any missing module dependencies (Endjin.RecommendedPractices.Build & InvokeBuild) and executes
    the build process.
.PARAMETER Tasks
    Optionally override the default task executed as the entry-point of the build.
.PARAMETER Configuration
    The build configuration, defaults to 'Release'.
.PARAMETER BuildRepositoryUri
    Optional URI that supports pulling MSBuild logic from a web endpoint (e.g. a GitHub blob).
.PARAMETER SourcesDir
    The path where the source code to be built is located, defaults to the current working directory.
.PARAMETER CoverageDir
    The output path for the test coverage data, if run.
.PARAMETER TestReportTypes
    The test report format that should be generated by the test report generator, if run.
.PARAMETER PackagesDir
    The output path for any packages produced as part of the build.
.PARAMETER LogLevel
    The logging verbosity.
.PARAMETER Clean
    When true, the .NET solution will be cleaned and all output/intermediate folders deleted.
.PARAMETER BuildModulePath
    The path to import the Endjin.RecommendedPractices.Build module from. This is useful when
    testing pre-release versions of the Endjin.RecommendedPractices.Build that are not yet
    available in the PowerShell Gallery.
.PARAMETER BuildModuleVersion
    The version of the Endjin.RecommendedPractices.Build module to import. This is useful when
    testing pre-release versions of the Endjin.RecommendedPractices.Build that are not yet
    available in the PowerShell Gallery.
.PARAMETER InvokeBuildModuleVersion
    The version of the InvokeBuild module to be used.
