---------------------------------
Summary: CLONE - ASTTest annotation has runtime retention and
transform removes required member from AST
Key: GROOVY-9723
URL: https://issues.apache.org/jira/browse/GROOVY-9723
Project: Groovy
Issue Type: Bug
Reporter: Eric Milles
Assignee: Eric Milles
Consider the following:
{code:groovy}
import groovy.transform.*
import org.codehaus.groovy.ast.*
import static org.codehaus.groovy.transform.stc.StaticTypesMarker.*
class C {
void m() {
def that = this;
{ ->
@ASTTest(phase=INSTRUCTION_SELECTION, value={
ClassNode type = node.getNodeMetaData(INFERRED_TYPE)
assert type?.name == 'C'
})
def ref = getThisObject()
assert ref == that
}()
}
}
{code}
This is a typical use of {{@ASTTest}}. When compiled, the test annotation is
retained in the class file, which is unnecessary. When the transform class
runs, it removes the "value" member from the AST, which is causing compiler
errors down the line when {{ExtendedVerifier}} runs {{AnnotationVisitor}}.
Also, the variable scope of the test closure is still connected to the class
and module, so code completion is making proposals for class members which will
not be there at run-time.
This was originally investigated from the IDE side (see linked issue).
