Björn Kautler created GROOVY-12301:
--------------------------------------
Summary: STC does not resolve generic return type properly
Key: GROOVY-12301
URL: https://issues.apache.org/jira/browse/GROOVY-12301
Project: Groovy
Issue Type: Bug
Affects Versions: 4.0.31, 5.0.3, 6.0.0-alpha-1
Reporter: Björn Kautler
Given this snippet:
{code:java}
@Grab('org.jboss.weld:weld-spock:4.0.4.Final')
import org.jboss.weld.spock.WeldInitiator
import org.jboss.weld.spock.WeldInitiator.Builder
@groovy.transform.CompileStatic
class Foo {
def foo() {
Builder builder =
WeldInitiator.from(WeldInitiator.createWeld()).inject(this)
println(builder)
}
}
new Foo().foo() {code}
STC complains
{code:java}
Cannot assign value of type
org.jboss.weld.junit.AbstractWeldInitiator$AbstractBuilder to variable of type
org.jboss.weld.spock.WeldInitiator$Builder {code}
IntelliJ knows the type of the {{inject}} result properly as {{{}Builder{}}},
and in Java it also compiles fine.
(This time I verified it still happens in 6.0.0-alpha-1 which is available in
groovyconsole.dev :))
