.jar File Not Generating In Android Studio

I'm working project which requires another project's .jar file. I'm using android studio 2.3.3. Following is code to generate .jar file task clearJar(type: Delete) { delete 'build/

Solution 1:

I was facing the same problem earlier, I resolved it by clearing invalidated cache and restart studio.

Go to file -> Invalidate caches and restart. It will take time.

Solution 2:

On Android studio 3.1+ the build path got changed. So change the path to "build/intermediates/packaged-classes/release/". May it help some one.

task makeJar(type: Copy)
{
    from('build/intermediates/packaged-classes/release/')
    into('build/outputs/')
    include('classes.jar')
    rename ('classes.jar', 'NAME.jar')
}

Solution 3:

Add this line into your app build.gradle file under the dependencies.

implementation fileTree(include: ['*.jar'], dir: 'libs')
