Re: [aspectj-users] Compile error

[Dave Whittaker <dave@xxxxxxxxxx>]

I just had this problem recently myself.  The trick seems to be to change the AspectJ dependencies for the aspectj-maven-plugin.  My config is below, but I use a private repo, so your artifacts would likely be different:

<plugin>

<groupId>org.codehaus.mojo</groupId>

<artifactId>aspectj-maven-plugin</artifactId>

<dependencies>

<dependency>

<groupId>aspectj</groupId>

<artifactId>aspectjrt</artifactId>

<version>1.6.1</version>

</dependency>

<dependency>

<groupId>aspectj</groupId>

<artifactId>aspectjtools</artifactId>

<version>1.6.1</version>

</dependency>

</dependencies>

<executions>

<execution>

<goals>

<goal>compile</goal>

<goal>test-compile</goal>

</goals>

</execution>

</executions>

<configuration>

<showWeaveInfo>true</showWeaveInfo>

<verbose>true</verbose>

<complianceLevel>1.5</complianceLevel>

<source>1.5</source>

<target>1.5</target>

</configuration>

</plugin>

Hi Joel,

That is certainly fixed in more recent builds, I just tried it:

1 error

no errors.

However, I don't know how to adjust your maven stuff...

I have an interface like this:

public interface EventListener<EVENTTYPE>
{
       <EV extends EVENTTYPE> void handle(EV event);
}

And I'm creating a class that implements it such as:

EventListener<SomeEvent> s = new EventListener<SomeEvent>() {
                       public <V extends SomeEvent> void handle(final V event)
                       {
// ...
                       }
}

I have tried it in non-anonymous case as well.
Compilation gives an error saying:

The type new EventListener<SomeEvent>(){} must implement the inherited
abstract method EventListener<SomeEvent>.handle(EV)

When using the eclipse or javac compiler, there is no error.

To complicate the question, I'm using maven for build, this for the compiler:
                               <groupId>org.codehaus.mojo</groupId>
                               <artifactId>aspectj-maven-plugin</artifactId>
                               <version>1.1-SNAPSHOT</version>

And I think that results in aspectj 1.5.4 being used, though if you
know how to change it so it will use more recent, please tell me.

Thanks!
