Re: [aspectj-users] AspectJ + Scala: Not working

[Andy Clement <andrew.clement@xxxxxxxxx>]

I can only assume it is the way you are building it.  I took your
pieces and did as follows and it worked for me:

javac CallJava.java -d output

scalac CallScala.scala -d output

ajc -inpath output TestAspect.aj -showWeaveInfo
Join point 'method-execution(void CallScala.call())' in Type
'CallScala' (CallScala.scala:3) advised by before advice from
'TestAspect' (TestAspect.aj:2)
Join point 'method-execution(void CallJava.call())' in Type 'CallJava'
(CallJava.java:3) advised by before advice from
'TestAspect'(TestAspect.aj:2)

scalac Test.scala

java -classpath
"\scala-2.8.0.final\lib\scala-library.jar;..\lib\aspectjrt.jar;." Test
Start application
Before call aspect !!
Scala called
Before call aspect !!
Java called
