unable to configure javascript JS files with WRO4J in eclipse

WRO4J is working fine with CSS files in the project but unable to configure JS file.
Here is what I did in WEB-INF/wro.xml:

<groups xmlns="http://www.isdc.ro/wro">
    <group name="all">
        <css>/asset/css/*.css</css>
        <css>/asset/css/lib/*.css</css>
        <js>/asset/js/lib/jquery-3.5.1.min.js</js>
        <js>/asset/js/lib/popper.min.js</js>
        <js>/asset/js/lib/bootstrap.min.js</js>
        <js>/asset/js/lib/bootstrapValidator.min.js</js>
        <js>/asset/js/lib/all.js</js>
        <js>/asset/js/*.js</js>
    </group>
</groups>

Please advise

Best Regards
