jetty-maven-plugin and loadTimeWeaver

Question

can't seem to have my spring webapp working with jetty-maven pluging

i always get

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loadTimeWeaver': Initialization of bean failed; nested exception is java.lang.IllegalStateException: ClassLoader [org.eclipse.jetty.webapp.WebAppClassLoader] 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

though i have:

• set MAVEN_OPTS to javaagent:/Users/blabla/.m2/repository/org/springframework/spring-instrument/3.1.3.RELEASE/spring-instrument-3.1.3.RELEASE.jar
• set JAVA_OPTIONS to the same thing
• added dep to spring-instrument and spring-aspects
• added jvmArgs with -javaagent:.... to jetty-maven-plugin configuration

Answer 1

Probably you are missing few jars aspectjweaver aspectjrt spring-instrument

Additionally you may want to try explicitly defining the bean loadTimeWeaver in applicationcontext.xml file.

    <property name="loadTimeWeaver">
        <bean id="instrumentationLoadTimeWeaver" class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver"/>
    </property>
