Description
I faced pretty strange annotations-related behavior (bug?) with scala macro. Its pretty hard to describe it in one message so I decided to create a sample repo to show it.
https://github.com/akozhemiakin/sandbox-one
In brief, here is the test itself:
package sandbox
import org.scalatest.FunSuite
import sandbox.sub.B
class SandboxSpec extends FunSuite {
class A[T](el: T)
test("Test 1") {
// Here we use simple macro to return number of annotations attached to the "foo" method of the A type arg
assert(Macro.annosOnFoo(new A(new C)) == 1) // Will succeed
}
test("Test 2") {
// Exactly the same case as above. The only difference: B is not in the same package as A and this test
assert(Macro.annosOnFoo(new A(new B)) == 1) // Will fail
}
}So the problem is, that in the second case scala does not see any annotations attached to the target method.
I did my best to find some similar issue but did not succeed, hope it is not a duplicate.
