Gradle Apk版本。 失败（：applyRetrolambda失败）

Question

I am trying to migrate a maven project to gradle. so far i'v had success with the 'run Task' (the app is running in eclipse fine) but i am failing to generate an apk file.

build.gradle file:

'`

    buildscript {
        ext {
            springBootVersion = '2.0.3.RELEASE'
        }

    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.3.12'
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'org.javafxports.jfxmobile'
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = 'io.rainrobot.wake'

mainClassName = 'io.rainrobot.wake.android.GluonApplication'

repositories {
    maven {
        url 'http://nexus.gluonhq.com/nexus/content/repositories/releases'
    }
    mavenCentral()
}

        // Do not edit the line below. Use Gluon Mobile Settings in your project context menu instead
        plugins 'display', 'lifecycle', 'statusbar', 'storage'
    }
    android {
        manifest = 'src/android/AndroidManifest.xml'

            androidSdk='C:/Users/Roy 1/android-sdks'
    }
    ios {
        infoPList = file('src/ios/Default-Info.plist')

Answer 1

Are you sure you want to port to Android that app with all those dependencies?

If that's the case, I'm afraid it won't be possible.

When the retrolambda task fails in your case:

java.lang.RuntimeException: Failed to backport class: org/springframework/http/server/reactive/UndertowServerHttpResponse
...
java.lang.ClassNotFoundException: io.undertow.server.handlers.Cookie

the reason is a ClassNotFoundException , what means that the dependency is not available.

In other words, you need to resolve all the transitive dependencies of your build.gradle list for the Android tasks.

In this case, the problem with the Spring framework is its use of optional for dependencies.

Based on this answer , it seems all the optional dependencies have to be manually added (like runtime or androidRuntime dependency).

In this case, the list of optional dependencies is quite big. The same goes for all the different related frameworks, like spring-core .

I took the time to add one by one all the required dependencies to pass the retrolambda task:

So now you will pass the retrolambda task, but then you will run into the next issue:

> Task :GluonApplicationTestApp:mergeClassesIntoJar FAILED
Execution failed for task ':GluonApplicationTestApp:mergeClassesIntoJar'.
> archive contains more than 65535 entries.

If you check the folder \\build\\javafxports\\tmp\\android\\retrolambda , you will notice that there 500 MB of more than 150000 *.class files. And even if you could create a dex file with all those entries, the size of the application will be huge.

In conclusion, you should check for other alternatives that don't involve adding a huge back-end into a client mobile app.

You can check for instance this sample that uses Spring in the back-end, and Gluon Mobile in the client, with CloudLink to connect both.
