How to use Perf4J with Profiled annotation in Gradle project?

I have a Java Gradle project for which I am trying to use Perf4J. I found some examples of Perf4J only Maven. So, I modified one and ran it. Here is the Java class and Maven build file that works.

package com.mycompany.testapplication;

import org.apache.log4j.Appender;
import org.apache.log4j.ConsoleAppender;
import org.apache.log4j.Level;
import org.apache.log4j.Logger;
import org.apache.log4j.SimpleLayout;
import org.perf4j.aop.Profiled;

/**
 *
 * @author Ankit Gupta
 */
public class TestClass {

    final static Logger myLogger = Logger.getLogger("org.perf4j.TimingLogger");
    final static Appender myAppender;

    static {
        myLogger.setLevel(Level.ALL);
        // Define Appender     
        myAppender = new ConsoleAppender(new SimpleLayout());

        //myAppender.setLayout(new SimpleLayout());  
        myLogger.addAppender(myAppender);
    }

    public static void main(String[] args) {
        TestClass test = new TestClass();
        test.run();
    }

    @Profiled(
            tag = "sampleTag"
    )
    private void run() {
        try {
            Thread.sleep(5000);
        } catch (InterruptedException ex) {
            java.util.logging.Logger.getLogger(TestClass.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        }
    }

}

and the pom.xml

The code above works fine and gives me the expected output. Now, I want to do the same to my gradle project, but I don't know how. Since, I am using @Profiled annotation, I realized that I want AspectJ. I found this plugin and wrote a build.gradle file for the same Java class as follows:

apply plugin: 'java'

sourceCompatibility = '1.6'

if (!hasProperty('mainClass')) {
    ext.mainClass = 'com.mycompany.testapplication.TestClass'
}

buildscript {
    repositories {
        maven {
            url "https://maven.eveoh.nl/content/repositories/releases"
        }
    }

    dependencies {
        classpath "nl.eveoh:gradle-aspectj:1.4"
    }
}

repositories {
    mavenCentral()
}

dependencies{
    compile 'org.perf4j:perf4j:0.9.16'
    compile 'org.aspectj:aspectjrt:1.6.7'
    compile 'org.perf4j:perf4j:0.9.13:log4jonly'
    compile 'commons-jexl:commons-jexl:1.1'
    compile 'log4j:log4j:1.2.17'
}

project.ext {
    aspectjVersion = '1.6.7'
}

apply plugin: 'aspectj'

The gradle build clean and gradle run commands do not give any error or warning. However, I do not see the perf4j log on the console. How can I fix this so that I can use perf4j with Gradle?

You forgot to specify the external code to weave in (the line with ajInpath). I adopted your script (included application plugin to execute with gradle run, updated version numbers and changed to Java 8:

buildscript {
    repositories {
        maven { url "https://maven.eveoh.nl/content/repositories/releases" }
    }

    dependencies {
        classpath "nl.eveoh:gradle-aspectj:1.4"
    }
}

project.ext {
    aspectjVersion = '1.8.1'
}

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

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.perf4j:perf4j:0.9.16:log4jonly'
    compile 'org.aspectj:aspectjrt:1.8.1'
    compile 'commons-jexl:commons-jexl:1.1'
    compile 'log4j:log4j:1.2.17'

    ajInpath 'org.perf4j:perf4j:0.9.16:log4jonly'
}

sourceCompatibility = '1.8'
mainClassName = 'com.mycompany.testapplication.TestClass'

Tested with Gradle 2.0. It would be a good idea to put the version numbers into variables and to use the gradle wrapper.
