java - How to tell maven to compile a project as an aspectj project -

my project:

src/main/aspects:

com  |---badmitrii         |---trace.aj 

src/main/java:

com  |---badmitrii         |---app.java 

i wrote following pom:

<project xmlns="http://maven.apache.org/pom/4.0.0" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="http://maven.apache.org/pom/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">     <modelversion>4.0.0</modelversion>     <groupid>com.badmitrii</groupid>     <artifactid>aspectj-test</artifactid>     <packaging>jar</packaging>     <version>1.0-snapshot</version>     <name>aspectj-test</name>     <url>http://maven.apache.org</url>     <dependencies>         <dependency>             <groupid>org.aspectj</groupid>             <artifactid>aspectjrt</artifactid>             <version>1.6.11</version>         </dependency>     </dependencies>      <build>         <plugins>             <plugin>                 <groupid>org.codehaus.mojo</groupid>                 <artifactid>aspectj-maven-plugin</artifactid>                 <configuration>                     <aspectlibraries>                         <aspectlibrary>                             <groupid>com.badmitrii</groupid>                             <artifactid>aspectj-test</artifactid>                         </aspectlibrary>                     </aspectlibraries>                 </configuration>             </plugin>             <plugin>                 <groupid>org.codehaus.mojo</groupid>                 <artifactid>exec-maven-plugin</artifactid>                 <version>1.2.1</version>                 <executions>                     <execution>                         <goals>                             <goal>java</goal>                         </goals>                     </execution>                 </executions>                 <configuration>                     <mainclass>com.badmitrii.app</mainclass>                 </configuration>             </plugin>             <plugin>                 <!-- build executable jar -->                 <groupid>org.apache.maven.plugins</groupid>                 <artifactid>maven-jar-plugin</artifactid>                 <version>2.4</version>                 <configuration>                     <archive>                         <manifest>                             <addclasspath>true</addclasspath>                             <classpathprefix>lib/</classpathprefix>                             <mainclass>com.badmitrii.app</mainclass>                         </manifest>                     </archive>                 </configuration>             </plugin>         </plugins>     </build> </project> 

but jar still being compiled java-project , when run java -jar <jar-name> didn't desirable aspectj result.

how tell maven compile jar respect aspects?

upd:

app.java:

package com.badmitrii;

public class app  {     public static void main( string[] args )     {         app  = new app ();         a.m();     }      public void m(){         system.out.println("test");     } } 

trace.aj:

package com.badmitrii.aspects;  public aspect trace {     pointcut publicmethodexecuted(): execution(public !static * *(..));      after(): publicmethodexecuted() {         system.out.printf("enters on method: %s. \n", thisjoinpoint.getsignature());          object[] arguments = thisjoinpoint.getargs();         (int =0; < arguments.length; i++){             object argument = arguments[i];             if (argument != null){                 system.out.printf("with argument of type %s , value %s. \n", argument.getclass().tostring(), argument);             }         }         system.out.printf("exits method: %s. \n", thisjoinpoint.getsignature());     } } 

try configuring plugin the documentation describes:

in order apply compiled aspects own sources need setup jar files weave in plugin configuration shown below.

which be

       <plugin>             <groupid>org.codehaus.mojo</groupid>             <artifactid>aspectj-maven-plugin</artifactid>             <configuration>                 <aspectlibraries>                     <aspectlibrary>                         <groupid>com.badmitrii</groupid>                         <artifactid>aspectj-test</artifactid>                     </aspectlibrary>                 </aspectlibraries>             </configuration>            <executions>              <execution>                <goals>                  <goal>compile</goal>                </goals>              </execution>            </executions>         </plugin>

updated after code post:

however, yours not pre-compiled aspect. don't need configuration of aspectlibraries, need goal:

       <plugin>             <groupid>org.codehaus.mojo</groupid>             <artifactid>aspectj-maven-plugin</artifactid>            <executions>              <execution>                <goals>                  <goal>compile</goal>                </goals>              </execution>            </executions>         </plugin> 

also, should add version of maven-plugin:

<artifactid>aspectj-maven-plugin</artifactid> <version>1.7</version> 

this compile aspect if comment out printf lines (they not written correctly, , beyond scope of question). may test system.out.println("i inside aspect") inside aspect see works.

like:

package com.badmitrii.aspects;  public aspect trace {     pointcut publicmethodexecuted(): execution(public !static * *(..));      after(): publicmethodexecuted() { //        system.out.printf("enters on method: %s. \n", thisjoinpoint.getsignature());         system.out.println("inside aspect - after");         object[] arguments = thisjoinpoint.getargs();         (int =0; < arguments.length; i++){             object argument = arguments[i];             if (argument != null){ //                system.out.printf("with argument of type %s , value %s. \n", argument.getclass().tostring(), argument);             }         } //        system.out.printf("exits method: %s. \n", thisjoinpoint.getsignature());     } }
