Running Unit Tests using Maven in Spring LTW Environment - spring

Question

I am developing an application in a ddd architecture using Spring LoadTimeWeaving feature. The problem is i can run my Junit tests using eclipse but not through Maven. I have tried all the options given on various sites but it simply isn't working. I get the following exception:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loadTimeWeaver': Initialization of bean failed; nested exception is java.lang.IllegalStateException: ClassLoader [sun.misc.Launcher$AppClassLoader] does NOT provide an 'addTransformer(ClassFileTransformer)' method. Specify a custom LoadTimeWeaver or start your Java virtual machine with Spring's agent: -javaagent:org.springframework.instrument.jar
I have added the instrument jar as a part of argLine to surefire plugin. Following are my code artifacts. Please let me know where i am going wrong or if there is any other solution.
I am using Eclipse Indigo for Development, Maven 3.0 on Mac OSX

Answer 1

you need to include a spring-instrument.jar agent as:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.4</version>
<configuration>
<forkMode>once</forkMode>
<argLine>
-javaagent:"${settings.localRepository}/org/springframework/spring-instrument/${spring.framework.version}/spring-instrument-${spring.framework.version}.jar"
</argLine>
<useSystemClassloader>true</useSystemClassloader>
</configuration>
</plugin>
( replace ${spring.framework.version} and ${settings.localRepository} with your values )
and of course an AspecJ Maven plugin as:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>aspectj-maven-plugin</artifactId>
<version>1.3</version>
<executions>
<execution>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
<goals>
<goal>compile</goal> <!-- use this goal to weave all your main classes -->
<goal>test-compile</goal> <!-- use this goal to weave all your test classes -->
</goals>
</execution>
</executions>
</plugin>
For AspectJ to work, you would also need to add an aspectjrt dependency:
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjrt</artifactId>
<version>${aspectjrt.version}</version>
</dependency>
Here a full example on how to run AspectJ tests with Maven
