Tar Extract Fails on Zip Repos Submodules: Solution
When working with repositories that contain submodules, you may encounter issues when trying to extract and use them. One such issue is the failure of the tar command to extract a Zip file containing submodules. This article will discuss the problem in detail and provide a solution.
Problem: Tar Extract Fails on Zip Repos Submodules
The problem occurs when you download a repository as a Zip file from GitHub and then try to extract it using the tar command. The error message you receive may look something like this:
This error occurs because the tar command is not designed to handle submodules within Zip files. When you download a repository as a Zip file, GitHub does not include the submodules in the Zip file. Instead, it includes a .gitmodules file that contains information about the submodules. When you extract the Zip file, the .gitmodules file is extracted, but the actual submodules are not.
Solution: Use Git to Clone the Repository
The solution to this problem is to use Git to clone the repository instead of downloading it as a Zip file. Cloning the repository will ensure that all submodules are downloaded and extracted correctly. Here's how to do it:
Step 1: Install Git
If you don't have Git installed on your system, you can download it from the official Git website: https://git-scm.com/downloads.
Step 2: Clone the Repository
To clone the repository, open a terminal and navigate to the directory where you want to clone the repository. Then, use the following command:
Replace org and repo-with-submodules with the actual organization and repository name. This command will clone the repository and all its submodules to your local system.
Step 3: Extract the Repository
After cloning the repository, you can extract it using the tar command:
This command will extract the repository and all its submodules to a new directory with the same name as the repository.
In conclusion, the tar command is not designed to handle submodules within Zip files. To avoid this issue, it's recommended to use Git to clone the repository instead of downloading it as a Zip file. This will ensure that all submodules are downloaded and extracted correctly.
