Issue using within Java 7 project

[awjones76]

This plugin is compiled using Java 8 which is causing issues within my Android project (using Java 7). I receive the following error within my Android project when trying to use this plugin: "Unsupported major.minor version 52.0".

If I change my Android project to use JDK 8, then the plugin works but I would rather not use JDK 8 within my project since it is not yet officially supported.

Is there something I am doing wrong, or is it possible to update this plugin so it is compatible with Java 7?

I just hit the same problem (masked by very confusing java.lang.IllegalStateException: buildToolsVersion is not specified.)

Are there any plans to fix this?

We are currently exploring making the plugin compatible with Java 7. In the meantime, the recommended course of action is to use the Java 8 SDK in Android Studios.

kkozmic-seek,

buildToolsVersion is not specified.

is typically thrown when the android gradle plugin is misconfigured.

Using the sample at http://developer.android.com/tools/building/configuring-gradle.html:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile project(":lib")
    compile 'com.android.support:appcompat-v7:19.0.1'
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

That error occurs when

buildToolsVersion "19.0.0"

is removed from the android gradle configuration.

Hi @michael-b-willingham thanks for getting back to me.

Any ETA for when Java 7 support will go live?

As for the buildToolsVersion issue, I think it's a red herring. We most definitely have that configured in our build.gradle (set to buildToolsVersion "23.0.2" if that makes any difference to device farm plugin)

[michael-b-willingham]

We're actively working on the java 7 support for this plugin. You can expect to see a pull request soon.

[awjones76]

Awesome... Looking forward to Java 7 support!

[michael-b-willingham]

Here's the pull request. Once it gets reviewed, I'll upload the artifacts to maven central as v1.2 and push the changes to the awslabs master repo.

nicely done @michael-b-willingham

[michael-b-willingham]

The new artifacts were deployed to maven. You should be good to try it. Here's the new gradle dependency:

classpath 'com.amazonaws:aws-devicefarm-gradle-plugin:1.2'
