Not able to integrate AspectJ with Maven

Question

I banged my head for two days to integrate aspectj with maven, But did not work. I am writing a simple program with two advices (which works fine in eclipse, so I am sure it's not a code side error).

I have recently started using maven for project building. Can't think of why I am not able to kick off aspectj compiler.

During compilation through maven - I get only class file for java without weaving. .aj file is not compiled.

Please Help!!!!

the first aspect file - ExceptionAspects.aj

package com.aspectSample;

public aspect ExceptionAspects {

pointcut ExceptionHandler(Exception e) : handler(Exception+) && args(e) && within(com.clickable.*);
pointcut callbeforeMethod():execution( public void HelloWorldExclude.*(..)) ;

before(Exception ex) : ExceptionHandler(ex)
{       
    System.out.println("Added Aspects before Exception :"+ex.toString());
}

before(): callbeforeMethod()
{
    System.out.println("Aspect Before Method Call");
}


pointcut sysOutOrErrAccess() : get(* System.out) || get(* System.err);

declare error
  : sysOutOrErrAccess()
  : "Don't write to the console";

}

The source java file HelloWorldExclude.java package com.aspectSample;

    import java.sql.SQLException;

    public class HelloWorldExclude {

 private void FoulIntro(String message, String name) throws SQLException
    {
        throw new SQLException("WriteSomething");
    }

 public void GiveMeFoulIntro(String message, String name)
    {
        try
        {
            this.FoulIntro(message, name);

        }catch(SQLException exp)
        {
            System.out.println("catching exception");
        }
    }
}

and the pom.xml file is

A couple of things that you can try:

Explicitly provide the dependencies of the maven-aspectj plugin:

    <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>aspectj-maven-plugin</artifactId>
        <version>1.4</version>
        <dependencies>
            <dependency>
                <groupId>org.aspectj</groupId>
                <artifactId>aspectjrt</artifactId>
                <version>${aspectj.version}</version>
            </dependency>
            <dependency>
                <groupId>org.aspectj</groupId>
                <artifactId>aspectjtools</artifactId>
                <version>${aspectj.version}</version>
            </dependency>
        </dependencies>

with the version of aspectjrt and aspectjtools matching the version of aspectj that you are using.

Do you by any chance have any of your sources in the test folder, with the src/test folder, then to weave the aspects to the test sources you will have to explicitly mention that in the maven-aspectj plugin:

            <executions>
            <execution>
                <goals>
                    <goal>compile</goal>
                    <goal>test-compile</goal>
                </goals>
            </execution>
        </executions>

There was a stupid mistake in pom file. aspectj plugin was added under element, which is just a configuration of all plugins. It doesn't tell compiler what to use.

It worked as soon as I removed plugin out of this element.

Thanks Pankaj
