Downloading Your Application

Python 2.7/3.7 | Java 8 |PHP 5.5/7.2 |Go 1.9/1.11 |Node.js

You can download an application's files by running the appcfg.sh command with the download_app action.

appcfg.sh -A [YOUR_PROJECT_ID] -V [YOUR_VERSION_ID] download_app [OUTPUT_DIR]

where:

• [YOUR_PROJECT_ID] is your GCP project ID.
• [YOUR_VERSION_ID] is the version ID of your application that you want to download.
• [OUTPUT_DIR] is the full directory path to where you want your files downloaded.

For more information about this command, see the appcfg.sh download_app reference.

If the command is successful, you get output similar to the following:

Getting file list...
Fetching files...
Getting files...

[1/5] request.class
[2/5] login.class
[3/5] static/screen.css
[4/5] static/print.css
[5/5] images/bird.png

Tip: GCP project owners can permanently disable all users' ability to view or download an application's files through the App Engine Settings page of the GCP Console.

Troubleshooting

Command not found

If you installed the Google Cloud SDK and use the gcloud tool, the appcfg.sh command is available from the [SDK_INSTALL_PATH]/google-cloud-sdk/platform/google_appengine/ directory.

For example, to use the Google Cloud SDK, you run the appcfg.sh by specifying the directory path:

[SDK_INSTALL_PATH]/google-cloud-sdk/platform/google_appengine/appcfg.sh -A [YOUR_PROJECT_ID] -V [YOUR_VERSION_ID] download_app [OUTPUT_DIR]

Important: You must have the App Engine extension installed with the Google Cloud SDK. If you receive a "path does not exist" error, run gcloud components install app-engine-java to install the App Engine SDK as a component of your Google Cloud SDK installation. See Installing the SDK for App Engine for Java for the complete set of installation steps.

You do not have permission to download this app version

Only the authenticated user who deployed the version of the application as well as the users with the project Owner role have the privileges to download files. Other users who attempt to download the application will receive an error message similar to the following:

Fetching file list...
Error 403: --- begin server output ---
You do not have permission to download this app version.
--- end server output ---

Note: Users that have been granted the App Engine Code Viewer role are able to view the application files through the Stackdriver Debug page in the GCP Console.
