how to choose the environment in app engine gradle plugin ?

[chanseokoh]

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.

gradle.build

    buildscript {
        repositories {
            mavenCentral()
        }
        dependencies {
            classpath 'com.google.cloud.tools:appengine-gradle-plugin:2.4.5'
        }
    }
    
    plugins {
        id 'java'
        id 'org.springframework.boot' version '2.5.4'
        id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    }
    
    apply plugin: 'com.google.cloud.tools.appengine'
    
    repositories {
        mavenCentral()
        maven { url "https://packages.jetbrains.team/maven/p/ij/intellij-dependencies" }
        flatDir {
            dirs 'lib'
        }
        google()
    }
    
    dependencies {
        testImplementation platform('org.junit:junit-bom:5.9.1')
        testImplementation 'org.junit.jupiter:junit-jupiter'
    
        implementation 'com.google.firebase:firebase-database:20.0.1'
        implementation 'com.google.firebase:firebase-admin:9.0.0'
        // https://mvnrepository.com/artifact/org.json/json
        implementation group: 'org.json', name: 'json', version: '20230618'
    
        implementation 'org.springframework.boot:spring-boot-starter-web'
        implementation 'org.springframework.boot:spring-boot-starter'
        testImplementation 'org.springframework.boot:spring-boot-starter-test'
    }
    
    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 ?
