Migrating to the new version of sbt-aspectj

[hasansozer]

I am trying to compile and run a tool, which is using an old version of sbt-aspectj (com.typesafe.sbtaspectj" % "sbt-aspectj" % "0.5.3"). I updated the plugins.sbt file to switch to the new version ("com.lightbend.sbt" % "sbt-aspectj" % "0.11.0"). I updated the build file as well. The original build file can be found in this link: https://github.com/samira-t/Bita/blob/master/project/Build.scala

Hereby, I updated the import statements as follows:

mport com.lightbend.sbt.SbtAspectj import com.lightbend.sbt.AspectjKeys.{ aspectjInputs, aspectjBinaries, aspectjWeave }

Then I updated the library dependencies as follows:

libraryDependencies ++= Seq( "com.typesafe.akka" %% "akka-actor" % "2.4.1", "org.scalatest" %% "scalatest" % "2.2.4" % "test", "org.scala-lang" % "scala-reflect" % "2.11.7", "org.scala-lang.modules" %% "scala-xml" % "1.0.4" ),

The following definition does not work since "inputs in Aspectj" is apparently not defined anymore:

inputs in Aspectj <<= update map { report => report.matching(moduleFilter(organization = "com.typesafe.akka", name = "akka-actor")) },

So, I changed it as follows (hoping that this value in AspectjKeys is representative):

aspectjInputs <<= update map { report => report.matching(moduleFilter(organization = "com.typesafe.akka", name = "akka-actor")) },

I changed the last two lines for using the instrumented versions as well (hoping that they are comparable to the use of AspectjPlugin.useInstrumentedClasses and AspectjPlugin.useInstrumentedJars):

fullClasspath in Test <<= SbtAspectj.aspectjUseInstrumentedClasses(Test), fullClasspath in Runtime <<= SbtAspectj.aspectjUseInstrumentedClasses(Runtime)))

Assuming that the above modifications are correct, the part that I am really puzzled with is the definition of an aspect filter as copied below:

aspectFilter in Aspectj := { (jar, aspects) => { if (jar.name.contains("akka-actor") ) aspects filter (jar => (jar.name.startsWith("Actor"))) else Seq.empty[File] } },

Apperrently such a filter is not defined in the version. I also could not find a representative definition.

Hi, sorry for the late response. Let's see if this can help you:

• aspectjInputs still needs to be scoped to the Aspectj configuration, despite it's prefix. i.e.: aspectjInputs in Aspectj <<= update map { ... }
• Your use case looks very very similar to this specific example: https://github.com/sbt/sbt-aspectj/blob/master/src/sbt-test/weave/external/build.sbt. It's about instrumenting an external JAR file and then reusing it later in a different module. You might be interested on mimic part of it.
• You are using a very old version of SBT, 0.12.x, the latest version of this plugin it's only being tested with SBT 0.13.5+ and 1.0.x. Upgrading SBT to the latest will also force you to change the <<= syntax though.

Thank you for help. Scoping leads to a compile error in my case (keyword Aspectj is not recognized); however, I will study and try to mimic the statements in the example build file. I will also try to upgrade the SBT version.
