Build fails due to missing dx.jar

Question

Whenever I try to build the project, it shows the following error,

Error:Execution failed for task ':app:transformClassesWithDexForDebug'>  com.android.build.api.transform.TransformException: java.lang.RuntimeException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: java.lang.IllegalStateException: dx.jar is missing

I have recently updated my sdk and after that uninstalled android studio unchecking the sdk and downloaded the IDE(just because I wanted to update studio) without sdk and made it to use the present sdk.

Please help! I am not finding any solution working yet.

There is no option for update, I already have the updated ones — Urja Pawar, May 18 '16 at 07:20

Did you update your build.gradle as well?

sample:

android {
    compileSdkVersion 24 // this is important
    buildToolsVersion "24" // this also

    defaultConfig {
        applicationId "org.bamboomy.yarne"
        minSdkVersion 15
        targetSdkVersion 24 // recommended
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.0.0' // and don't forget this
    compile 'com.android.support:design:24.0.0' // and this
}

I'm not an expert but it seems that in the

C:\Users\myusername\AppData\Local\Android\sdk\build-tools\23.0.2

dir there is no dx.jar (only a dx.bat)

and beginning from 23.0.3 there seems to be a

C:\Users\myusername\AppData\Local\Android\sdk\build-tools\23.0.3\lib

folder with a dx.jar present

Deleting sdk platform tools and build tools and reinstalling them worked for me.

It's related to your buildToolsVersion config in build.gradle

Go to your SDK path and find the build-tools directory and search for dx.jar file. Each folder that has dx.jar file could be your buildToolsVersion.

If not exist any dx.jar use SdkManager to download one build-tools

The error has nothing to do with the dex method limit, so this answer isn't applicable. – JesusFreke May 18 '16 at 17:05
