I get a similar issue with Android gradle plugin 3.1.0 and Timber 4.7.0

ClassCastException:WrongTimberUsageDetector.isLoggingExceptionMessage(WrongTimberUsageDetector.java:552)←WrongTimberUsageDetector.chekExceptionLogging(WrongTimberUsageDetector.java:514)←WrongTimberUsageDetector.visitMethod(WrongTimberUsageDetector.java:95)←UElementVitor$DelegatingPsiVisitor.visitMethodCallExpression(UElementVisitor.kt:1027)←UElementVisitor$DelegatingPsiVisitor.visitCallExpression(UElementVisitor.kt:1007)←KotlinUFunctionCallExpression.accept(KotlinUFunctionCallExpression.kt:114)←UQualifiedReferenceExpression$Defaulmpls.accept(UQualifiedReferenceExpression.kt:48)←KotlinUQualifiedReferenceExpression.accept(KotlinUQualifiedReferenceExpression.kt:29)

Edit: I found the statement that caused the error: Timber.e(error, error.message) and fixed it by replacing it with Timber.e(error)

Seems to me like this is an issue within Lint / UAST. Here’s a test case that won’t even jump into the visitMethod method:

@Test fun exceptionLoggingUsingExceptionMessageArgumentInKotlin() {
  lint()
      .files(TIMBER_STUB,
          kt("""
              |package foo
              |import timber.log.Timber
              |class Example {
              |  fun log() {
              |     Exception e = Exception()
              |     Timber.d(e, e.message)
              |  }
              |}""".trimMargin())
      )
      .issues(WrongTimberUsageDetector.ISSUE_EXCEPTION_LOGGING)
      .run()
      .expect("""
          |src/foo/Example.kt:6: Warning: Explicitly logging exception message is redundant [TimberExceptionLogging]
          |     Timber.d(e, e.message)
          |     ~~~~~~~~~~~~~~~~~~~~~~
          |0 errors, 1 warnings""".trimMargin())
      .expectFixDiffs("""
          |Fix for src/foo/Example.java line 5: Remove redundant argument:
          |@@ -6 +6
          |-      Timber.d(e, e.message)
          |+      Timber.d(e)
          |""".trimMargin())
}
