#Requires -Version 5.1
<#
.SYNOPSIS
    Runs a full end-to-end CI test build of nsis-plugin-ns7zip on the Linux template.

.DESCRIPTION
    Invokes Invoke-CIJob.ps1 with the ns7zip repo parameters targeting the Linux
    build template (LinuxBuild2404) and verifies the artifact was produced.
    The Linux build cross-compiles Windows DLLs via mingw-w64.

    Exits 0 on success, 1 on failure.

.PARAMETER JobId
    Job identifier used for artifact and log directory names.
    Default: e2e-ns7zip-linux-<yyyyMMdd_HHmmss>

.PARAMETER Branch
    Branch to build. Default: main

.PARAMETER Commit
    Optional specific commit SHA. Default: empty (HEAD of branch).

.PARAMETER Config
    Plugin config to build: x86-ansi | x86-unicode | x64-unicode. Default: x64-unicode

.PARAMETER ZipVersion
    7-Zip version (Linux-supported subset): 25.01 | 26.00 | 26.01 | zstd. Default: 26.01

.PARAMETER TemplatePath
    Path to the Linux template VMX. Default: env:GITEA_CI_LINUX_TEMPLATE_PATH or
    F:\CI\Templates\LinuxBuild2404\LinuxBuild2404.vmx

.PARAMETER SnapshotName
    Snapshot name to clone from. Default: BaseClean-Linux

.PARAMETER SshKeyPath
    SSH private key for the ci_build user in the guest. Default: F:\CI\keys\ci_linux

.PARAMETER UseGitClone
    If set, skips host-side git clone and delegates cloning to the guest VM.
    Uses -GuestRepoUrl (HTTP) instead of the SSH alias URL.
    Mirrors the -UseGitClone mode of Invoke-CIJob.ps1 (same as §3.3 for Windows).

.PARAMETER GuestRepoUrl
    HTTP(S) URL used for in-VM clone when -UseGitClone is set.
    Must be reachable from inside the Linux guest VM.
    Default: https://gitea.emulab.it/Simone/nsis-plugin-ns7zip.git

.PARAMETER VerifyArtifact
    If set, expands artifacts.zip (or scans the dir) and checks that at least one DLL is present.
    Default: $true
