[aspectj-users] How to compile interfaces with default implementations
|
Hello everyone
I'm reading AspectJ in Action (2nd edition) and downloaded the source
code from http://www.manning.com/laddad2/AspectJInActionSecondEdition-sources-1.0.0.zip.
I'm now trying to compile the project
"ch05\workspace\Section5.1.5ExampleVersion2". It's about interfaces
that have a default implementation like:
public interface Nameable {
public void setName(String name);
public String getName();
static aspect Impl {
private String Nameable.name;
public void Nameable.setName(String name) {
this.name = name;
}
public String Nameable.getName() {
return this.name;
}
}
}
When compiling the project, I get compilation errors:

It seems as if the aspectj-maven-plugin is not executed, although it
is configured in the parent project. I also tried to put the following
plugin configuration in the project's pom itself, with the same
result:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>compile</goal>
<goal>test-compile</goal>
</goals>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
I'm using maven 3.0.3. Any ideas?
Best regards,
James
