Java 8 has reached end of support
and will be
deprecated
on January 31, 2026. After deprecation, you won't be able to deploy Java 8
applications, even if your organization previously used an organization policy to
re-enable deployments of legacy runtimes. Your existing Java
8 applications will continue to run and receive traffic after their
deprecation date. We recommend that
you
migrate to the latest supported version of Java.
Migrating from AppCfg to gcloud Command Line
Stay organized with collections
Save and categorize content based on your preferences.
AppCfg was a utility command that was included in the App Engine
SDK.
To help you replace your use of AppCfg commands with gcloud commands
from the gcloud CLI, see the following table:
appcfg command |
gcloud command line |
download_app |
You can no longer download source files, but you can view them from the Google Cloud console Versions page by selecting Source in the Diagnose column. |
request_logs |
gcloud app logs read or view and route logs with the Logs Explorer |
rollback |
No longer supported or necessary |
start_module_version |
gcloud app versions start |
stop_module_version |
gcloud app versions stop |
update |
For Python and PHP apps:
gcloud app deploy
For Java 8 apps, build the app first. Then deploy with:
gcloud app deploy WEB-INF/appengine.xml
For Java 11 apps, you can deploy the source code to the Java 11 runtime
without building locally:
gcloud app deploy pom.xml
To deploy a Java fatjar to the Java 11 runtime:
gcloud app deploy myapp.jar
You can also use the gcloud CLI-based
Maven or
Gradle plugins to
build and deploy Java 8 and Java 11 apps.

gcloud beta app migrate-config datastore-indexes-xml-to-yaml MY-INDEX-XML-FILE.xml
gcloud beta app migrate-config dispatch-xml-to-yaml MY-DISPATCH-XML-FILE.xml
gcloud beta app migrate-config queue-xml-to-yaml MY-QUEUE-XML-FILE.xml
