And its corresponding package also configured.y
But when I’m trying to run the program it throws some errors like;dg How to fix this ? …
Or else Is there any other way to add the external jars in CUBA 7.0 ?

Make sure you have added the dependencies for the web module:

configure(webModule) {
    configurations {

    dependencies {
        // add your dependencies here
