I create a simple JavaSE app using Weld SE.
I'm I try to run with gradle run it throws an exception:

:compileJava UP-TO-DATE

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.

I have tried the solution provided by @drenedo (sorry I don't have enough reputation for comment), the following code works fine with me:

sourceSets.main.resources {

    exclude 'META-INF/beans.xml'

}

classes {

    doLast{

        copy {

            from('src/main/resources') { include 'META-INF/beans.xml' }

            into "$buildDir/classes/java/main/"

        }

    }

}

And I'm a little confused about what the following code is intended for. Since src/main/resources/META-INF/beans.xml and $buildDir/classes/main/META-INF/beans.xml are not directories, this code would cause an error. So I just simply delete it:

inputs.dir 'src/main/resources/META-INF/beans.xml'

outputs.dir "$buildDir/classes/main/META-INF/beans.xml"

And the solution answered by @J. Lenthe also works fine with me.

Also you can try this bean-discovery-problems-when-using-weld-se-with-gradle-application-plugin :

task copyResources(type: Copy) {

    from "${projectDir}/src/main/resources"

    into "${buildDir}/classes/java/main"

}

processResources.dependsOn copyResources

Gradle 4+ uses a different output directory for the classes, so remember to use ${buildDir}/classes/java/main instead of ${buildDir}/classes/main.

I solved this issue by adding sourceSets.main.resources in the build.gradle:

sourceSets.main.resources {

   exclude 'META-INF/beans.xml'

}

  classes {

   inputs.dir 'src/main/resources/META-INF/beans.xml'

   outputs.dir "$buildDir/classes/main/META-INF/beans.xml"

} << {

   copy {

      from('src/main/resources') { include 'META-INF/beans.xml' }

      into "$buildDir/classes/main/"

   }

}

With the given example:

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'

}



sourceSets.main.resources {

   exclude 'META-INF/beans.xml'

}

  classes {

   inputs.dir 'src/main/resources/META-INF/beans.xml'

   outputs.dir "$buildDir/classes/main/META-INF/beans.xml"

} << {

   copy {

      from('src/main/resources') { include 'META-INF/beans.xml' }

      into "$buildDir/classes/main/"

   }

}



sourceCompatibility = '1.8'

version = '1.0'

mainClassName = 'br.com.alexpfx.crawler.run.Main'
