Import the file into psakefile.ps1 using the Include Function. A script block that returns a boolean value. False means validation has failed to cause the whole script to stop. Assuming you have the PSake project from GitHub on your local machine, you’ll first need to run through a few steps to get it set up.
- The name psakefile.ps1 is not mandatory, but it is the default name expected by the engine.
- You will learn about these advantages as you read along.
- At a minimum, a task should have a name and an action block.
- PostAction – A script block to run right after the task has completed with success.
The important word here is cleanly since the build pipeline will be building in a clean environment. Forgetting to add a file to VCS is a common mistake that will let you successfully build locally, but will lose a cycle on the build. In addition, Get-Help provides help content for all of the other functions inside the psake module. Since psake is just a PowerShell module with functions inside, it can use all of the functionality and discoverability that makes PowerShell so easy to use. To get a complete list of all parameters possible for each task, psake has built-in help. This makes it easy to scour through all of the options available.
Notice in the example below the $installSqlOn_C_Drive and $installSqlOn_D_Drive variables. When Invoke-PSake invokes this script, these variables will contain a True or False value depending on if a C or D volume exists. Let’s build these files one by one with minimal implementation. At the top of the file, set strict mode and framework then dot-source any other files. With PowerShell, you can easily install a printer driver, add a printer to the repository, and then add a… This command is intended to be used within the Package Manager Console in Visual Studio, as it uses the NuGet module’s version of Install-Package.
The small amount of extra work it takes pays back big time in the medium and long terms. To do so, define a hashtable with each of the key/value pairs you’d like to override. Then, pass the hashtable to the Properties parameter. https://bitcoin-mining.biz/ engine will use the values in the passed-in hashtable over those specified in the Properties block within the psakefile.ps1 script. At this stage, you’re not actually building the code to do anything; you’re simply scaffolding out the tasks and creating the PSake file.
Versions
28.9K Hangfire.Build Psake tasks and functions to build Hangfire projects with ease. For example, maybe you have a Pester test to confirm the SQL setup ZIP file exists in a folder after you run the DownloadSql task. In that case, you build a simple Pester test and invoke the DownloadSql task within the test and check for the ZIP file right after it runs. Wherever you can invoke a PowerShell script, you can invoke a PSake file.
If used, any errors that may occur during the task runtime will not cause the whole script to break. PostAction – A script block to run right after the task has completed with success. PreAction – A script block to run prior to the task.

Function that can delete a directory, whether empty or not, we use here in cleanup tasks. Build Reusable Functions – these are some of the basic powershell functions we need to build, so that use them later in the process. This functionality was working perfectly fine and then suddenly stopped working. No changes were made to project files or VS Code besides monthly updates. I am able to build the file using the shortcut (CTRL+SHIFT+B) or by using the command “Invoke-Psake -BuildFile FilePath” in the vscode command line.
This is helpful when running in an Azure DevOps pipeline that’s on a hosted machine since it may not have what you need to run the build. The script below is a sample that installs psake, SQL Change Automation, and VsSetup then callInvoke-psakewith parameters. You’ll see that at its heart, psake is just a task management engine made for software builds. A container for one or more commands that, when performed together, achieve a certain goal. These commands go into a script block that is passed to the Action parameter.
The basic steps for creating a psake build
You will need to “unblock” the zip file before extracting – PowerShell by default does not run files downloaded from the Internet. Just right-click the zip and click on “properties” and click on the “unblock” button. Clean the solution using dotnet clean command, in addition to directories like bin, obj, etc. This section defines variables that you can reference in anytaskin the script, like a global. They can be overridden on the command line. The following list are the basic steps to get building with psake.
Otherwise the ERP Software Development Services Custom ERP Solutions GitHub site has directions for installing it. Note that to run unsigned PowerShell scripts locally, you should issue the following command from an Administrative PowerShell prompt. You can see that psake executed a PowerShell script, which contained three tasks called Clean, Compile, and Test. Psake allows you to define these tasks and any dependencies required among them to execute PowerShell code within each task. To make sure you have all dependencies installed , you can wrap psake with a simple script to install such modules.
A task has many advantages over a function. You will learn about these advantages as you read along. Setting Up Properties/Variables – these are the variables required by the tasks (restore, build, test, etc.). We can keep the solution name and project name same for simplicity.
Azure DevOps
You will usually have a high-level task for devs to run for a quick build, and one for a build with tests that they should run before committing to VCS. Psake executes the Task functions and enforces the dependencies between tasks. Since psake is written in a real programming language and not XML, you have a lot more freedom and flexibility in your build scripts. You can use all the features of PowerShell and the .NET Framework within your build.
The precondition parameter allows you to define code that will return either $true or $false. If it returns $false, the task will not run at all. Each Task is a function that can define dependencies on other Task functions. The code you produce with PSake becomes more readable, maintainable, and easier to test. After some practice you will find that dividing your steps to different tasks makes them easier to script.
You’ll notice the Write-Host references in the tasks below; you’ll be adding to the tasks later. Create a script named psakefile.ps1 with a single task. At a minimum, a task should have a name and an action block. The name psakefile.ps1 is not mandatory, but it is the default name expected by the engine. But now you’ve got a disorganized mess of scripts and modules with a hodgepodge of manual script executions, scheduled tasks, and more.
If You Unscramble PSAKE… What Does It Mean?
Get many of our tutorials packaged as an ATA Guidebook. Time summary with the duration of each task, plus the total duration of the whole script. Now run Get-Module PSake -ListAvailable to confirm it shows up. If you don’t receive an error, you’re ready to proceed. Extract the PSake zip file downloaded from GitHub. Anyone can fork the main repository and submit patches, as well.
To ensure you can manage all of those tasks, you should focus on modularization or splitting tasks up to make things easier to manage. Using the InstallSqlDriveD task from the example above as a starting point, perhaps you have an additional request for the installation. Depends – A name of a task that must run before the current task is executed. PSake will use this information to execute the task dependencies in the right order. E.g., if task A is dependent on task B, then PSake engine will run B before A.
Each of these tasks is defined inside of a single pssakefile.ps1 script. If you anticipate adding more many more tasks over time, you should split those tasks up into separate files with each task inside e.g. ValidateDiskSpace.ps1, DownloadSql.ps1, InstallSqlDriveD.ps1, InstallSqlDriveD.ps1, etc.
Based on the sample we built above, we can execute the build from a command line using build.cmd or ./build.sh which uses the default task. Configure-build.ps1 – this script is called first, which configures the dependencies. In another blog post we looked atCake, which is the C# cousin of psake. The depends parameter is just one of many useful parameters you can pass to each task. Also useful are a couple of the validation parameters called precondition and requiredvariable.
