Kotlin Error : Could not find org.jetbrains.kotlin:kotlin-stdlib-jre7:1.0.7

replace

                                       JDK = Java Development Kit

Since the version with jre is absolute , just replace and sync the project

Official Documentation here Thanks for the link @ ROMANARMY

In Project level build.gradle use only this version

ext.kotlin_version = '1.3.31'

Remove other versions

This will only work with the latest version of android studio 3.4

UPDATE: Try to use the latest version of kotlin with latest Android studio to avoid an error.

The split of kotlin-stdlib into kotlin-stdlib-jre7 and kotlin-stdlib-jre8 was only introduced with Kotlin 1.1, that's why the dependency cannot be resolved, the package version simply does not exist.

It looks like the update to your project files failed at some point and set the Kotlin version to 1.0.7. If this is a new project and there's nothing holding you back from using 1.1.1, I'd switch to that. Your problem should be gone after doing this.

In "build.gradle" file, change current Kotlin version that line and press synk:

ext.kotlin_version = '1.1.1'

/// That will look like:

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

buildscript {
    ext.kotlin_version = '1.1.1'
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

Starting with Kotlin 1.1.2, the dependencies with group org.jetbrains.kotlin are by default resolved with the version taken from the applied plugin. You can provide the version manually using the full dependency notation like:

compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"

If you're targeting JDK 7 or JDK 8, you can use extended versions of the Kotlin standard library which contain additional extension functions for APIs added in new JDK versions. Instead of kotlin-stdlib, use one of the following dependencies:

compile "org.jetbrains.kotlin:kotlin-stdlib-jdk7"
compile "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
