After update to Android Studio 2.2 / gradle plugin

问题:

After updating Android Studio to version 2.2 and the Gradle-plugin to 2.2.0, I get following error:

"Could not get unknown property 'assembleRelease' for project ':app' of type org.gradle.api.Project."

When I change the plugin version back to 2.1.3 the code still works, but that's no long-term option for me.

My code:

apply plugin: 'com.android.application'

dependencies {
...
}

android {
...
}

...    
assembleRelease.doLast {
  file('build/outputs/apk/app-release.apk').renameTo("AppName-1.0.0-${project.ext.androidVersionCode}.apk")
}

Hint: project.ext.androidVersionCode is a variable defined otherwhere and contains a build number. The code in assembleRelease.doLast shall just move/rename the generated apk file.

Thank you for advices! tangens

You may rewrite your task a bit and try like this:

task renameBuildTask() << {
  file('build/outputs/apk/app-release.apk').renameTo("AppName-1.0.0-${project.ext.androidVersionCode}.apk")
  dependsOn 'assembleRelease'
}

Also you can check this question to get better understanding.

EDIT

As @tangens said in a comment:

It works when I replace the call gradle assemble by e.g. gradle renameBuildTask. Thank you! The answer contains an error. Correct would be: task renameBuildTask() << { ... }

回答2:

tasks.whenTaskAdded { task ->
  if (task.name == 'assembleRelease') {
    task.finalizedBy 'yourRenameTasks'
  }
}

回答3:

maybe wrap code in afterEvaluate{} will be work:

afterEvaluate {
    assembleRelease.doLast {
       file('build/outputs/apk/app-release.apk').renameTo("AppName-1.0.0-${project.ext.androidVersionCode}.apk")
    }
}

gradle-2.14.1 and android gradle plugin 2.2.0

details: Could not get unknown property 'assembleDebug' (2.2-beta)

I had the same problem after upgrading Android Studio to 2.2 and Gradle to 2.2. I have task copyApk that needs to be run at the end of building. For brevity, let me skip what was working before, and post only what is working right now:

tasks.create(name: 'copyApk', type: Copy) {
    from 'build/outputs/apk/myapp-official-release.apk'
    into '.../mobile'
    rename('myapp-official-release.apk', 'myapp.apk')
}

tasks.whenTaskAdded { task ->
    if (task.name == 'assembleRelease') {
        task.dependsOn 'copyApk'
    }
}

Gradle console shows copyApk was run near the end after packageOfficialRelease, assembleOfficialRelease, right before the last task assembleRelease. "Official" is a flavor of the app. I got the workaround from this SO post. I essentially copied the answer here for your convenience. All credits go to the author of that post.

inside buildTypes {} method, I put this code : worked like a charm

task setEnvRelease << {
            ant.propertyfile(
                    file: "src/main/assets/build.properties") {
                entry(key: "EO_WS_DEPLOY_ADDR", value: "http://PRODUCTION IP")
            }
        }

        task setEnvDebug << {
            ant.propertyfile(
                    file: "src/main/assets/build.properties") {
                entry(key: "EO_WS_DEPLOY_ADDR", value: "http://DEBUG IP TEST")
            }
        }
tasks.whenTaskAdded { task ->
            if (task.name == 'assembleDebug') {
                task.dependsOn 'setEnvDebug'
            } else if (task.name == 'assembleRelease') {
                task.dependsOn 'setEnvRelease'
            }
        }

回答6:

you can do this:

task copyApk(dependsOn: "assembleRelease") << {
    file('build/outputs/apk/app-release.apk').renameTo("AppName-1.0.0-${project.ext.androidVersionCode}.apk")
}
