Re: [aspectj-users] [aspectj plugin] weaving jars to other projects + 3r

[Michael Rogger <Michael.Rogger@xxxxxxx>]

Hi Simone,

thx for the fast reply. The plugin part from the project where the 
aspect is located is the following:

           <plugin>
               <groupId>org.codehaus.mojo</groupId>
               <artifactId>aspectj-maven-plugin</artifactId>
               <executions>
                   <execution>
                       <goals>
                           <goal>compile</goal>
                       </goals>
                   </execution>
               </executions>
               <configuration>
                   <source>1.6</source>
                   <target>1.6</target>
                   <verbose>true</verbose>
                   <outxml>false</outxml>
                   <showWeaveInfo>true</showWeaveInfo>
                   <aspectDirectory>src/main/aspectj</aspectDirectory>
                   <testAspectDirectory>src/test/java</testAspectDirectory>
               </configuration>
           </plugin>

And the next plugin part is in another project where I inject the 
compiled aspects into:


           <plugin>
           <groupId>org.codehaus.mojo</groupId>
           <artifactId>aspectj-maven-plugin</artifactId>
           <executions>
             <execution>
             <phase>compile</phase>
               <goals>
                 <goal>compile</goal>
               </goals>
             </execution>
           </executions>
           <configuration>
             <source>1.6</source>
             <target>1.6</target>
             <verbose>true</verbose>
             <outxml>false</outxml>
             <showWeaveInfo>true</showWeaveInfo>
               <aspectLibraries>
                   <aspectLibrary>
                       <groupId>wsmx</groupId>
                       <artifactId>wsmx-securitymanager</artifactId>
                   </aspectLibrary>
               </aspectLibraries>
           </configuration>
           </plugin>


The error trace:
