Cannot build a project in Android Studio

Question

I am trying to import a project in Android Studio. This code supposedly works but I cannot seem to be able to build the project. This is the error that is produced when I am trying to build:

Error:Execution failed for task ':openCVLibrary2410:compileReleaseJava'.

Cannot find System Java Compiler. Ensure that you have installed a JDK (not just a JRE) and configured your JAVA_HOME system variable to point to the according directory.

I have searched for a solution, but what I found was was either referring to eclipse or changing the jdk position for

File > other Settings > Default Project Structure

Which is not a valid solution for me because I checked my previous Android Studio Projects and all have the same position

This is the stacktrace:

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task     ':openCVLibrary2410:compileReleaseJava'.

mainProject Gradle:

// Top-level build file where you can add configuration options common to      all sub-projects/modules.
buildscript {
     repositories {
         jcenter()
     }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'
    }
}

 allprojects {
    repositories {
        jcenter()
    }
}

FaceRecognition Gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
buildToolsVersion "21.1.2"

defaultConfig {
    applicationId "eu.upcom.recred.facerec"
    minSdkVersion 9
    targetSdkVersion 9
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'),     'proguard-rules.txt'
        }
    }
}

dependencies {
     compile files('libs/javacpp.jar')
     compile files('libs/javacv.jar')
     compile project(':openCVLibrary2410')
 }

openCV2410 gradle

    apply plugin: 'com.android.library'

android {
    compileSdkVersion 19
    buildToolsVersion "21.1.2"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 8
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),     'proguard-rules.txt'
        }
    }
}

post your gradle file..because recently i used this library on my camera app — Vishal Senjaliya, Nov 29 '16 at 09:35
is you project and 'openCVLibrary2410' project in the same directory? — Atif Farrukh, Nov 29 '16 at 10:01
Check your java compiler path.Like this select file---->Other settings--->Default project structure and see your java path is properly set or not...because your gradle is perfect. — Vishal Senjaliya, Nov 29 '16 at 10:10

While I was posting here the gradle files my eye caught something. I changed the build tools version from 'com.android.tools.build:gradle:1.1.0' to 'com.android.tools.build:gradle:2.2.2'and now it is building as it should
