You can remove the archives .class before compiling the sources. I use a modified version of build file. Try: | <?xml version="1.0" encoding="UTF-8"?> | | <project default="run" name="JBossAOP"> | <property name="jboss.aop.root" value="/opt/project/library/jboss-aop"/> | <property name="jboss.aop.lib50" value="${jboss.aop.root}/lib-50"/> | <property name="buildpath" value="${basedir}/bin"/> | <property name="class.main" value="Driver"/> | | <target name="prepare"> | | <path id="jboss.aop.classpath50"> | <fileset dir="${jboss.aop.lib50}"> | <include name="*.jar"/> | </fileset> | </path> | | <path id="classpath"> | <path refid="jboss.aop.classpath50"/> | <pathelement path="."/> | </path> | | <property name="aop50jar" value="${jboss.aop.lib50}/jboss-aop-jdk50.jar"/> | | <path id="classpath50"> | <path refid="jboss.aop.classpath50"/> | <pathelement path="."/> | </path> | | <taskdef name="aopc" classname="org.jboss.aop.ant.AopC" classpathref="jboss.aop.classpath50"/> | </target> | | <target name="clean"> | <delete dir="${buildpath}" /> | <mkdir dir="${buildpath}" /> | </target> | | <target name="compile" depends="prepare"> | <javac srcdir="." | destdir="${buildpath}" | debug="on" | deprecation="on" | optimize="off" | includes="**"> | <classpath refid="classpath"/> | </javac> | <aopc compilerclasspathref="classpath" classpathref="classpath" verbose="true"> | <classpath path="${buildpath}"/> | <src path="."/> | <aopclasspath path="."/> | </aopc> | </target> | | <target name="run" depends="clean,compile"> | <java fork="yes" failOnError="true" className="${class.main}"> | <sysproperty key="jboss.aop.class.path" value="."/> | <classpath refid="classpath"/> | <classpath path="${buildpath}"/> | </java> | </target> | | <target name="compile50standalone" depends="prepare"> | <javac srcdir="." | destdir="." | debug="on" | deprecation="on" | optimize="off" | includes="**"> | <classpath refid="classpath50"/> | </javac> | </target> | | <target name="run.50.instrumented" depends="compile50standalone"> | <java fork="yes" failOnError="true" className="${class.main}"> | <sysproperty key="jboss.aop.class.path" value="."/> | <jvmarg value="-javaagent:${aop50jar}"/> | <classpath path="${buildpath}"/> | <classpath refid="classpath50"/> | </java> | </target> | | </project> | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3990749#...
