Could not initialize class org.jacoco.core.internal.flow.ClassProbesAdapter

[stanch]

Hi,

I’m having trouble running jacoco in my project. Here is the trace from last myProject/jacoco:fullClasspath:

The project aggregates several subprojects, and I get this same error whether the settings are applied to it or just to a single subproject. The settings revelant for tests look like this:

val testSettings = Seq(Test, jacoco.Config).flatMap { conf =>
  Seq(
    parallelExecution in conf := false,
    fork in conf := true,
    javaOptions in conf += "-Xmx2g",
    javaOptions in conf += "-javaagent:" + (dependencyClasspath in Test).value
      .files.find(_.name.endsWith(s"jmockit-${Versions.JMockit}.jar")).get,
    testOptions in conf += Tests.Argument(
      TestFrameworks.JUnit, "--ignore-runners=org.scalatest.junit.JUnitRunner"
    )
  )
} ++ jacoco.settings ++ Seq(
  ScoverageSbtPlugin.ScoverageKeys.coverageHighlighting := false,

  libraryDependencies ++= Seq(
    "org.scalatest" %% "scalatest" % "1.9.2" % "test",
    "de.bwaldvogel" % "mongo-java-server" % "1.2.0" % "test",

    "com.novocode" % "junit-interface" % "0.11" % "test",
    "junit" % "junit" % "4.11" % "test"
  )
)

I guess it might be related to this because of our similar exception stack trace.
jacoco/jacoco#177

Just managed to get this same error after upgrading from 3.1.0 to 3.2.0. No info what causes it.

There are several files that give this error, but this is one of them:

package macros

import scala.language.experimental.macros

object CopyWithId {
  import scala.reflect.macros.whitebox

  def withId[T, I](entity: T, id: I): T = macro withIdImpl[T, I]

  def withIdImpl[T: c.WeakTypeTag, I: c.WeakTypeTag](c: whitebox.Context)(entity: c.Expr[T], id: c.Expr[I]): c.Expr[T] = {
    import c.universe._

    val tree = reify(entity.splice).tree
    val copy = entity.actualType.member(TermName("copy"))

    copy match {
      case s: MethodSymbol if s.paramLists.flatten.map(_.name).contains(TermName("id")) =>
        c.Expr[T](
          Apply(
            Select(tree, copy),
            AssignOrNamedArg(Ident(TermName("id")), reify(id.splice).tree) :: Nil
          )
        )
      case _ => c.abort(c.enclosingPosition, "No eligible copy method!")
    }
  }
}

Manually upgrading to 0.8.4 resolves problem for me.

add this to project/plugins.sbt after addSbtPlugin("com.github.sbt" % "sbt-jacoco" % "3.2.0")

libraryDependencies ++= Seq(
  "org.jacoco"                  %  "org.jacoco.core"      % "0.8.4",
  "org.jacoco"                  %  "org.jacoco.report"    % "0.8.4",
)
