Problem compiling APK

[rasmusson]

I am trying to set up retrolambda for android but I am having some trouble. When Im trying to build a APK I get this error message. com.sun.tools.javac.code.Symbol$CompletionFailure: class file for java.lang.invoke.MethodType not found

Any Idea how to debug this further? Im running on mac Gradle wrapper version 2.9 JDK 1.8.0_40 JDK 1.7.0_05

Top level .gradle

    buildscript {
        repositories {
            jcenter()
        }
        dependencies {

            classpath 'com.android.tools.build:gradle:1.1.0'
        }
    }

    allprojects {
        repositories {
            jcenter()
        }
    }

Project Level .gradle

    buildscript {
        repositories {
            maven { url 'https://maven.fabric.io/public' }
            mavenCentral()
        }

        dependencies {
            classpath 'io.fabric.tools:gradle:1.+'
            classpath 'me.tatarka:gradle-retrolambda:3.2.4'
        }
    }

    repositories {
        maven { url 'https://maven.fabric.io/public' }
        mavenCentral()
    }

    apply plugin: 'com.android.application'
    apply plugin: 'io.fabric'
    apply plugin: 'me.tatarka.retrolambda'

    retrolambda {
        oldJdk JAVA7_HOME
        jdk JAVA8_HOME
        javaVersion JavaVersion.VERSION_1_7
    }

    android {
        compileSdkVersion 21
        buildToolsVersion "21.1.2"

        defaultConfig {
            applicationId "no.steras.ruter"
            minSdkVersion 16
            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
        }
    }

Check that JAVA8_HOME/JAVA7_HOME are resolving correctly.

[rasmusson]

I have these defined in gradle.properties JAVA8_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home" JAVA7_HOME="/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home"

Is there a good way I can check that they are resolved?

[rasmusson]

I added println JAVA7_HOME println JAVA8_HOME

In the build script. It prints "/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home" "/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home" This is correct

[emredirican]

I had a similar problem in our CI machine, which is also a mac. Like evant said, somehow environment variables weren't resolved correctly. I couldn't fix it via launchd for some reason, so I assigned the variables to CI tasks and agents, which solved my problem.

I guess you need to make sure the variables are resolved correctly where your scripts are executed.

[rasmusson]

As my last comment says, I am printing the variables and they correctly resolves to the location of the java bin folder on the corresponding jdk

I've had similar problem. Locally everything compiled fine whereas on Build server I received the error above. Build server and localhost have had same project configuration. Having set JAVA_HOME for System-wide environment variable to C:\Program Files\Java\jdk1.8.0_66 fixed the problem

[rasmusson]

JAVA_HOME is set to my JDK8

[mradzinski]

Same error here on Windows 10 using JDK1.8.0_66

[mradzinski]

Weirdly enough, I ended up solving the issue by swapping the plugins order:

apply plugin: 'me.tatarka.retrolambda' // <---
apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'

retrolambda {
    jdk System.getenv("JAVA8_HOME")
    oldJdk System.getenv("JAVA7_HOME")
    javaVersion JavaVersion.VERSION_1_7
}

I'm having what seems to be the same issue. If I build from within Studio it fails with the error

com.sun.tools.javac.code.Symbol$CompletionFailure: class file for java.lang.invoke.MethodType not found Error:Execution failed for task ':Autosense:compilePaidDebugJavaWithJavac'. Compilation failed; see the compiler error output for details.

But if I build from the terminal with Gradle it is successful.
