gradle-retrolambda: Unsupported major.minor version 52.0 2.5.0

Hi all FYI, It’s happening randomly for a couple of weeks now. I can get rid of it only adding

org.gradle.java.home=/Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home

to my gradle.properties. JAVA_HOME and JAVA8_HOME are properly set too. Ivan

Just a heads up, it was as simple as changing the SDK path in project settings to point to my JDK 8 home directory. I had started my project before including this plugin and was at that pointed to 7, but during setup for this library installed 8, but didn’t update my project settings. Updating the path fixed the issue for me. HTH

Note that current Anndroid tools/google libraries require JDK8 or you will get “Unsupported major.minor version 52.0”. This is true even if you are not using Retrolambda.

Change build gradle version it’s work for me before: -classpath ‘com.android.tools.build:gradle:2.2.0’ after: -classpath ‘com.android.tools.build:gradle:2.1.3’

I have the trable (Unsupported major.minor version 52.0) in fresh version classpath 'me.tatarka:gradle-retrolambda:3.2.3'. What did i do wrong? There is my gist https://gist.github.com/kolipass/ebaa82476a89946e0505 .

I try to use jvmArgs '-noverify' and projectlombok then i have lombok/ast/Node : Unsupported major.minor version 52.0 If i didn’t use projectlombok i received java.lang.UnsupportedClassVersionError Unsupported major.minor version 52.0 for every test.

Solution: export JAVA_HOME=$JAVA8_HOME

I also faced the same problem, it can be solved by following two steps:

Step 1: Download Java 8. Step 2: Update Android Studio to the latest version 2.2.

Hi All,

I was also facing same issue: Error:(1, 1) A problem occurred evaluating project ‘:app’.

java.lang.UnsupportedClassVersionError: com/android/build/gradle/AppPlugin : Unsupported major.minor version 52.0

I just updated JDK location on below setting(from “JDK 1.7” to "C:\Program Files\Android\Android Studio" and select the check box for Embedded JDK).

File->Other Settings=>Default Project Struture

For me I just had to restart Android Studio, lol.

I had the same problem. I tried changing JAVA_HOME in several variations but it didn’t help.

My solution was changing JDK location in module settings in Android Studio. Before this change it was set to java7 which was not working for me.

My build.gradle relevant parts look like this:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.fada21.android.x"
        minSdkVersion 10
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

apply plugin: 'me.tatarka.retrolambda'
retrolambda {
    jvmArgs '-noverify'
    jdk System.getenv("JAVA8_HOME")
    oldJdk System.getenv("JAVA7_HOME")
    javaVersion JavaVersion.VERSION_1_7
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile "com.android.support:appcompat-v7:21.0.3"

    retrolambdaConfig 'net.orfjackal.retrolambda:retrolambda:1.+'
}
