clone il2cpp_plus fail. url: {il2cppPlusRepoDir}

Error message

clone il2cpp_plus fail. url: {il2cppPlusRepoDir}

What it means

Thrown by InstallerController.PrepareLibil2cppWithHybridclrFromGitRepo when the il2cpp_plus repository directory is missing after CloneBranch. il2cpp_plus is the patched Unity IL2CPP source that hosts the hybridclr integration; the installer needs both repos to assemble the final libil2cpp.

Solutions

Confirm HybridCLRSettings.il2cppPlusRepoURL is correct and reachable (it must be the il2cpp_plus repo matching your Unity version branch).
Ensure the branch in _curDefaultVersion.il2cpp_plus.branch exists on that remote.
Re-run HybridCLR/Installer after fixing network/credentials; the installer will attempt both clones again.
Use InstallFromLocal if you have a pre-built libil2cpp-with-hybridclr directory to avoid cloning entirely.

Defensive patterns

Strategy: retry

Validate before calling

if (string.IsNullOrEmpty(HybridCLRSettings.Instance.il2cppPlusRepoURL))
    Debug.LogError("il2cppPlusRepoURL is empty in HybridCLR settings.");

Try / catch

try
{
    installer.PrepareLibil2cppWithHybridclrFromGitRepo();
}
catch (Exception ex) when (ex.Message.Contains("clone il2cpp_plus fail"))
{
    // Verify the branch exists on the remote, then retry; or use InstallFromLocal.
}

Prevention

Confirm both repo URLs and branches are correct in HybridCLR settings before installing.
Use InstallFromLocal for CI to avoid network dependency entirely.
Cache the cloned repos across installer runs to avoid re-cloning.

When it happens

Trigger: Same CloneBranch mechanism as error 185 but for il2cppPlusRepoURL. The directory check on il2cppPlusRepoDir fails, indicating the clone of the second repository did not succeed.

Common situations: Same network/auth/PATH causes as 185, plus: the hybridclr repo cloned fine but the il2cpp_plus URL is stale or points to a different host; the branch name configured for il2cpp_plus does not exist on the remote; partial network failure between the two clones.
