How Do I Recover My Extension After Deleting the Project?

Even after deleting a project, you can still recover your deployed extension's source files, if needed. Use the script provided below to retrieve the source files, which you can then import into a new workspace for continued testing and configuration work.

To do this, you'll need these details:

• The deployed extension ID and extension version

  (If you need help finding this information, file a service request and include as many details about your deployed extension as possible, such as the base application you're configuring and deployment date.)

• The URL of the environment where the extension was deployed
• Credentials of a user who can access the Oracle Cloud Applications instance

You'll also need to be able to edit and run a Python script, or use curl to duplicate what the Python script does.

1. Copy this Python script and save it as getDeployedExtension.py:

   import json
   import requests
   from requests.auth import HTTPBasicAuth
   import os
   
   #get extension file list
   response = requests.get('https://myoraclecloudappsinstance.fa.ocs.oraclecloud.com/fscmRestApi/vx/v2/extensions/Extension_ID/Extension_version',auth=('username','password'))
   
   response_dict = response.json()
   print(json.dumps(response_dict, indent=4)) #pretty print the json received through the above GET cmd
   
   #write a shell script file containing the curl commands to download the necessary extension files, while recreating the exact directory structure of the deployed extension
   if os.path.exists("curlFile.sh"): os.remove("curlFile.sh")
   baseURL=response_dict["baseUrl"]
   for x in response_dict["files"]:
     # ignore files in the extension-digest folder and bundles folder, and ignore build-info.json.
     if not (("bundle" in x) or ("build-info.json" in x) or ("extension-digest" in x)):
       with open('curlFile.sh', 'a', encoding="utf-8") as f:
         f.write("curl -u \"username:password\" --create-dirs -o " + response_dict["id"] + "/" + response_dict["version"] + "/" + "sources" + "/" +  x  + " " + baseURL + "/" + x + "\n\n")
   
   #run the shell script
   os.system("sh curlFile.sh")

2. In the script, replace the environment URL, Extension_ID, Extension_version, username, and password with your extension-specific values.
3. Run the script (recommended version is Python 3). For example:
   python3 getDeployedExtension.py
   The script creates a directory structure for the extension and extracts the source files into a sources subdirectory.
4. Create a .zip file of the sources subdirectory, only.

   Note:

   On a Mac, don't use the Finder to do this because it will create an archive that's incompatible with VB Studio.
5. In VB Studio, create a workspace with a scratch Git repository. We're using a scratch repository in this example, but you can use any Git repository that fits your own best practices.
6. Open the Source tab, right-click extension1, and click Import to import the sources.zip file into your workspace.

   The extension is now available in VB Studio for testing and validation.
