This sample demonstrates how to deploy an application on Google App Engine.
See the Google App Engine standard environment documentation for more detailed instructions.
- Java 8
- Maven (at least 3.5)
- Gradle (optional)
- Google Cloud SDK (aka gcloud)
• Download and initialize the Cloud SDK
gcloud init
- Create an App Engine app within the current Google Cloud Project
gcloud app create
- In the
pom.xml, update the App Engine Maven Plugin with your Google Cloud Project Id:
<plugin>
<groupId>com.google.cloud.tools</groupId>
<artifactId>appengine-maven-plugin</artifactId>
<version>2.2.0</version>
<configuration>
<projectId>myProjectId</projectId>
<version>GCLOUD_CONFIG</version>
</configuration>
</plugin>
Note: GCLOUD_CONFIG is a special version for autogenerating an App Engine
version. Change this field to specify a specific version name.
mvn package appengine:run
To use visit: http://localhost:8080/
If you encounter a "no_app_id" error when running your project locally, be sure to define your project ID with the GOOGLE_CLOUD_PROJECT environment variable:
export GOOGLE_CLOUD_PROJECT=<your-project-id>
mvn package appengine:deploy
To use vist: https://YOUR-PROJECT-ID.appspot.com
gradle appengineRun
If you do not have gradle installed, you can run using ./gradlew appengineRun.
To use vist: http://localhost:8080/
gradle appengineDeploy
If you do not have gradle installed, you can deploy using ./gradlew appengineDeploy.
To use vist: https://YOUR-PROJECT-ID.appspot.com
mvn verify
or
gradle test
As you add / modify the source code (src/main/java/...) it's very useful to add unit testing
to (src/main/test/...). The following resources are quite useful:
