appcfg.sh Command Line Arguments

Note: Instead of using appcfg and other App Engine SDK-based tooling, you can use Cloud SDK-based tooling, such as the gcloud command line, or the Cloud SDK-based Maven, Gradle, Eclipse, or IntelliJ plugins.

The appcfg.sh tool does a variety of application management tasks including deploying your app and updating datastore indexes. The appcfg tool is included with the App Engine SDK, which you can download and install at App Engine Java SDK.

Alternatives to appcfg command line for staging configuration

The command line staging options include the following:

• --enable_jar_splitting
• --jar_splitting_excludes=SUFFIXES
• --disable_jar_jsps
• --enable_jar_classes
• --delete_jsps

Instead of using these command line options, you should consider setting staging configuration in the application configuration file. This means you can set configuration once for your application instead of having to specifying configuration every time you deploy.
