What I understand is that it cannot find beans.xml file. But it is there in src/main/resources/META-INF/beans.xml:

<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
bean-discovery-mode="all"
        version="1.1">


</beans>

My main class is:

package br.com.alexpfx.crawler.run;
import org.jboss.weld.environment.se.*;
import javax.enterprise.inject.*;
import javax.inject.*;
import br.com.alexpfx.crawler.*;
public class Main {

    @Inject
    private @Named("SuperMarket") Crawler crawler;


    public static void main(String[] args) {
        Weld weld = new Weld();
        WeldContainer container = weld.initialize();
        Main main = container.instance().select(Main.class).get();
        main.run();
        weld.shutdown();
    }


    public void run() {

        System.out.println (crawler);

    }
}

the build gradle file is:

apply plugin: 'java'
apply plugin: 'application'



repositories{
    mavenCentral()
}


dependencies{
    // http://mvnrepository.com/artifact/org.jsoup/jsoup
    compile group: 'org.jsoup', name: 'jsoup', version: '1.9.1'

    // http://mvnrepository.com/artifact/org.jboss.weld.se/weld-se-core
    compile group: 'org.jboss.weld.se', name: 'weld-se-core', version: '2.3.4.Final'



}

sourceCompatibility = '1.8'
version = '1.0'
mainClassName = 'br.com.alexpfx.crawler.run.Main'

The problem is that gradle run does not build the jar file for your app. It simply compiles the classes and runs the main class with the resources directory on the classpath (do gradle --info run to see this for yourself). Weld requires a bean archive which is a jar file that contains META-INF/beans.xml or a war file that contains WEB-INF/classes/META-INF/beans.xml. It's not enough for beans.xml to just be on the classpath.

To get around this, since you're using the application plugin, just do a gradle installDist and run the shell script or batch file in build/install/myapp/bin.
