Questions tagged [appengine-maven-plugin]

Questions about either of the Google Maven plugins for App Engine and using the Jetty Maven plugin in conjunction with an App Engine project.

There are two appengine-maven-plugins that simplify development and add local debugging & deployment to Apache Maven. A plugin (docs) (github) based on the App Engine Java SDK for App Engine Standard, and a single integrated plugin (github) based on the Google Cloud SDK for both App Engine Standard (docs) and Flexible (docs). App Engine Flexible uses the Jetty Plugin for local debugging.
