You mean something like this?

set %ImAnEmptyMap = %();
set %RectangleProperties = %(Sides:4,Color:blue,Coordinates:%(x:10,y:15),Environments:@(Dev, QA, Prod));

The formal definition of a map

one of:

• a variable_expression for a map (%) type, or a
• a % character followed by left-parens ((), and any number of key-values pairs delimeted with commas (,), followed by a right-parens ()). A key-value pair consists of any_name, followed by a colon (:), followed by a literal_expression

Also yes you can create a map variable in the pipeline variables.

I'm looking to trigger a deployment failure at the beginning of a plan if a user-provided variable isn't valid. Based on the documentation here https://inedo.com/support/documentation/buildmaster/execution-engine/statements-and-blocks/other-statements it looks like there is a raise error command for this purpose however I can't seem to find any documentation on how to use it. What is the proper way to trigger a fatal error in a plan?

Package variables defined in a release template are not populated when creating a package from 'Packages'->'Create Release Package' (localhost:82/applications/7/packages). This results in a "Could not resolve variable" error during plan execution. The variables do populate when going through the release overview and clicking 'Create Package' (localhost:82/applications/7/releases/release?releaseNumber=1.9.0).

Is there a way to have variable expansion inside of another variable? It would be nice to be able to build up variables using other variables that are fully evaluated during execution.

{
  "CommonPath": "\common\path",
  "SpecificPath1": "$CommonPath\specific\place\here",
  "SpecificPath2": "$CommonPath\another\place\there"
}

Log-Information $SpecificPath2;

INFO:  \common\path\another\place\there

After updating from 5.5.3 to 5.6.2, plans utilizing the "Execute-PowerShell" command throw the following exception.

   Unhandled exception: System.MissingMethodException: Method not found: 'System.Nullable`1<Inedo.ExecutionEngine.RuntimeValue> Inedo.BuildMaster.Extensibility.Operations.IOperationExecutionContext.TryGetVariableValue(Inedo.ExecutionEngine.RuntimeVariableName)'.

I rolled back to 5.5.3 and verified my plans were working again and incrementally updated versions. It looks like the problem started occurring in 5.6.0

I have a map defined in my application settings as

{
"TestMap": "%(val1: foo, val2: bar)"
}

and I have a basic plan

for server MyTestServer
{
    set $test = $MapItem(%TestMap, val1);
    Execute-PowerShell >>
        $test;
        echo $test;
    >>;
}

But upon execution I am getting the following stack trace.

What is the correct way to define and access a map?

Can someone verify if the following behaviors are intended when writing scripts directly inside a PSExec operation?

1. Runtime variables are not evaluated when quoted.
2. Runtime variables are evaluated to empty when the script text is a single line.

I've created a small plan that illustrates the behavior.

##AH:UseTextMode
template foobar
{
    # General
    for server MyServer
    {
        set $var1 = foo;

        set $var2 = bar;

        Execute-PowerShell echo '$var1\$var2\test';

        Execute-PowerShell >>echo '$var1';
echo '$var2';
echo '$var1\$var2\test';>>;

        Execute-PowerShell echo $var1\$var2\test;

        Execute-PowerShell >>echo $var1;
echo $var2;
echo $var1\$var2\test;>>;

        Execute-PowerShell >>echo $var1;
echo $var2;
echo '$var1\$var2\test';>>;

        Execute-PowerShell >>echo '$var1';
echo '$var2';
echo $var1\$var2\test;>>;
    }
}

Also can someone provide a clear example of defining and accessing the inner values of a List type and a Map type variable? I see there is a ListItem function and a MapItem function but I am having trouble successfully using them.

Finally, is there any way to search the Q&A knowledge base other than tags? I'm sure this variable question has been asked before but the tag search seems pretty limited.

Is it possible to have each iteration of a loop block run in parallel? I know the general block can run statements in parallel but most of my build steps that can benefit from parallelism also benefit from being in a loop. i.e. applying database scripts

Thank you for the quick turnaround. However, I am still receiving an error due to a file not found. After upgrading extensions, the log now shows that the following path is trying to be hit:

Executing C:\BuildMaster\_SVCTMP\ExtTemp\Subversion\Resources\svn.exe

This path exists on the server hosting BuildMaster but does not exist on the agent server.

Which configuration is this exactly? When creating a new Subversion source control provider I do not see any property for executable path.

In addition I turned on the "Log command line arguments" option and found the following in the action log.

Executing C:\ProgramData\InedoAgent\BuildMaster\Temp\ExtTemp\Subversion\Resources\svn.exe

Your thought was correct and this path does not exist on the remote agent but there is a similar path at:

C:\ProgramData\InedoAgent\BuildMaster\ExtensionsTemp\Subversion\Resources\svn.exe

Is the Subversion extension supposed to be using the second path?

I am trying to create a simple plan that pulls the latest source code from a Subversion repository then runs MSBuild to compile the code before packing everything up in an artifact to be delivered to the next stage in the pipeline. When I set this plan to run under the "Local" agent on the machine hosting my instance of BuildMaster it works fine. However, when I change the plan to run on a remote Windows 7 machine that has an "Inedo" agent installed I receive the following stack trace:

Getting latest source code from path "/internaltools/"...
Ensuring local workspace at: C:\ProgramData\InedoAgent\BuildMaster\Temp\SrcRepos\qasubversion_81_svn_repos-internaltools_branches_2.4_2.4.0
