Gradle wrapper version issues

Question

My task is to build an apk file using gradle wrapper via command line. I have a project in Android Studio 2.2.3, it has a line in build.gradle file classpath 'com.android.tools.build:gradle:2.2.3', which should mean, that it is using gradle version 2.2.3. But when I call gradlew command from the project folder, there is always the same error: Unsupported major.minor version 52.0

I've used gradlew -v to recognize my gradle version, it is now 2.2.1. Though when I manually change gradle version in build.gradle file from 2.2.3 to 2.2.1 I still get the same error.

I checked the folder containing gradle on my computer. It has gradle version 2.14.1.

I tried:

changing JDK path from 1.7 to 1.8 (JAVA_HOME variable)
manually changing JDK location at Project Structure -> SDK Location settings
in gradle settings: switching between using default gradle wrapper and local gradle distribution.

Interesting thing is that when I change gradle version in build.gradle to 1.5.0 the version error disappears, but I can no longer make any builds(it becomes unable to merge several jar files into one apk file)

What is this version hell and how do I get rid of this error?

EDIT #1:

My /gradle/wrapper/gradle-wrapper.properties content is:

#Fri Oct 21 12:53:56 EEST 2016
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip

EDIT #2:

I figured out that gradle versions are the same. So what JDK and JRE version should I use and how do I update them? Simply downloading into Java folder and changing JDK location in Project Structure didn't help.

EDIT #3:

My build.gradle file:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        mavenCentral()
        flatDir {
            dirs 'libs'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'
        classpath 'com.google.gms:google-services:1.5.0-beta2'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        flatDir {
            dirs 'libs'
        }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

My project-level build.gradle file:

apply plugin: 'com.android.application'


android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.test.test"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])

    compile 'com.android.support:design:23.4.0'
    compile "com.android.support:support-v4:23.4.0"
    compile 'junit:junit:4.12'
    compile 'com.google.android.gms:play-services-ads:8.4.0'
}

SOLUTION:

I needed to update targetSdkVersion and all dependencies to version 25 and set JAVA_HOME to jdk 1.8. Thanks, Abhishek Aryan

@joe yes, first of all I've made all updates in Android Studio, including downloading the latest SDK tools. It made no difference. — Sam Stone

Gradle version is different from Android Plugin for Gradle version.

This is Android Plugin for Gradle with version

classpath 'com.android.tools.build:gradle:2.2.3'

And gradle with version

distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip
