Add support to analyze and package studio projects

[thschmitt]

Integrated uipathcli with UiPath Studio to build, package and analyze studio projects.

Added two new plugin commands:

• uipath studio package analyze
• uipath studio package pack

Implementation:

• Created infrastructure to download external plugins like the uipcli. The studio commands download the uipcli to the user cache dir and use it for packaging any studio project. Depending on the targetFramework the uipathcli either downloads the tool chain for building and packaging cross-platform or windows Studio projects.

• Added ExecCmd abstraction which is used to start processes and can easily be faked in unit tests in order to validate the behavior with different exit codes

• Refactored the existing browser launcher to use the ExecCmd abstraction

• Extended the progress bar rendering to allow displaying a simple bar without any percentage or bytes indicator so that the build process can be visualized without knowing the total time in advance.

• Increment the uipathcli version to 2.0. There are no backwards-incompatible changes. The major version increase only indicates that an important new feature has been added.

Examples:

uipath studio package analyze --source plugin/studio/projects/crossplatform

analyzing...        |██████████          |

{
  "error": null,
  "status": "Succeeded",
  "violations": [

  ]
}

uipath studio package pack --source plugin/studio/projects/crossplatform --destination . --debug

The following snippet allows users to package a local UiPath studio project, upload the package, create a release and run a job:

uipath studio package pack --source plugin/studio/projects/crossplatform --destination . --package-version 1.0.0
uipath orchestrator processes upload-package --file MyProcess.1.0.0.nupkg
$folderId = uipath orchestrator folders get --query "value[0].Id"
$releaseKey = uipath orchestrator releases post --folder-id $folderId --name "MyProcess" --process-key "MyProcess" --process-version "1.0.0" --query "Key" --output text
$jobId = uipath orchestrator jobs start-jobs --folder-id $folderId --start-info "ReleaseKey=$releaseKey" --query "value[0].Id" --output text
uipath orchestrator jobs get-by-id --folder-id $folderId --key $jobId
