how to choose the environment in app engine gradle plugin ?

[pradeepsimba]

I am using this plugin apply plugin: 'com.google.cloud.tools.appengine'.

I want to deploy my spring boot app on app engine's standard envronment. But , I have some doubts.

where do I represent the environment name ?

This is my project : https://github.com/Jeevasimba/appengine_example

my gradle file : https://github.com/Jeevasimba/appengine_example/blob/main/build.gradle

my YAML file : https://github.com/Jeevasimba/appengine_example/blob/main/src/main/appengine/app.yaml

what is difference between appengineDeploy and appengineDeployAll ?

I am new to gcloud app engine's standard environment .

### I referred online to deploy in standard env.

step 1: enable 'App engine Api'

step 2: INSTALL this sdk in projects terminal.

# Install the gcloud CLI
gcloud components install app-engine-java cloud-sdk

step 3: choosing server location

    # Create a new App Engine standard environment app
    gcloud app create

step 4: deploying

gradle appengineDeploy       

my doubt is where do I mention the environment's name as standard ?

This is my project : https://github.com/Jeevasimba/appengine_example. are there any mistake I have done in my project ?

is there any sample project with spring boot with gradle build for app engine's standard environment in github ?

help me to solve this problem !!!

You already specified the standard env in src/main/appengine/app.yaml.

runtime: java11
env: standard
instance_class: B8

But the current App Engine standard env doc doesn't mention the env element, so I'm guessing it defaults to standard when it's missing. OTOH, the flexible doc does say env: flexible is required.

env: flex Required: Select the flexible environment.

appengineDeployAll runs all the deploy tasks: appengineDeployCron, appengineDeployDispatch, appengineDeployDos, appengineDeployIndex, appengineDeployQueue, and most importantly, appengineDeploy. That is, it deploys all the YAML config files together with the app.

    }

    test {
        useJUnitPlatform()
    }

    appengine {
        deploy {
            stopPreviousVersion = true
        }
    }

below code is a common way to configure an App Engine app to stop the previous version when the new version is deployed using the gcloud command-line tool.

appengine {
    deploy {
        stopPreviousVersion = true
    }
}

If I push new code to github it will automatically deploy it on gcloud and stop the previous version app.

How do I do this with this plugin ?
