I am trying to compile using sbt-scala, however this error message keeps croppig up :
error can't determine superclass of missing type java.lang.Object
[error] when batch building BuildConfig[null] #Files=0 AopXmls=#0
[error] [Xlint:cantFindType]
[error] org.aspectj.bridge.AbortException: AspectJ failed
This is my build.sbt :
name := "testingAspectScalaFullexample"
version := "0.1"
scalaVersion := "2.13.5"
lazy val buildSettings = Seq(
organization := "com.lightbend.sbt.aspectj",
version := "0.1-SNAPSHOT",
scalaVersion := "2.12.1"
)
lazy val sample = (project in file("."))
.settings(buildSettings)
.aggregate(tracer, instrumented)
// precompiled aspects
lazy val tracer = (project in file("tracer"))
.enablePlugins(SbtAspectj)
.settings(buildSettings)
.settings(
// input compiled scala classes
aspectjInputs in Aspectj += (aspectjCompiledClasses in Aspectj).value,
// ignore warnings
aspectjLintProperties in Aspectj += "invalidAbsoluteTypeName = ignore",
aspectjLintProperties in Aspectj += "adviceDidNotMatch = ignore",
// replace regular products with compiled aspects
products in Compile := (products in Aspectj).value
)
// test that the instrumentation works
lazy val instrumented = (project in file("instrumented"))
.enablePlugins(SbtAspectj)
.settings(buildSettings)
.settings(
// add the compiled aspects from tracer
aspectjBinaries in Aspectj ++= (products in Compile in tracer).value,
// weave this project's classes
aspectjInputs in Aspectj += (aspectjCompiledClasses in Aspectj).value,
products in Compile := (products in Aspectj).value,
products in Runtime := (products in Compile).value
).dependsOn(tracer)
// for sbt scripted test:
TaskKey[Unit]("check") := {
import scala.sys.process.Process
val cp = (fullClasspath in Compile in instrumented).value
val mc = (mainClass in Compile in instrumented).value
val opts = (javaOptions in run in Compile in instrumented).value
val expected = "Printing sample:\nhello\n"
val output = Process("java", opts ++ Seq("-classpath", cp.files.absString, mc getOrElse "")).!!
if (output != expected) {
println("Unexpected output:")
println(output)
println("Expected:")
println(expected)
sys.error("Unexpected output")
} else {
print(output)
}
}
Could you kindly help me in trying to figure out this problem please ?
Thanks a lot :)
