Does anyone know if you can weave scala classes at compile time with aspectJ & spring. I have compile time weaving working for all my java classes but I can't seem to get it to work for my scala classes that use @Configurable.
For background I have been working on this for a couple of days. What a pain. Anyways here's the answer. Yes it can be done, you just can't use the aspectj maven plugin. You have to use the antrun maven plugin. Happy Scala Coding!
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.6</version>
<executions>
<execution>
<phase>compile</phase>
<goals>
<goal>run</goal>
</goals>
<configuration>
<target>
<taskdef resource="org/aspectj/tools/ant/taskdefs/aspectjTaskdefs.properties"
classpathref="maven.plugin.classpath" />
<iajc
srcDir="src/main/scala"
destDir="target/classes"
inpath="target/classes"
source="1.6"
aspectPath="${org.springframework:spring-aspects:jar}"
classpathRef="maven.compile.classpath"
Xlint="ignore" />
</target>
</configuration>
</execution>
</executions>

We got compile errors from aspectj-maven-plugin 1.0 that it missed Scala classes. An upgrade from to version 1.4 of the maven plugin solved that.
