Jochen Theodorou commented on GROOVY-6864:
------------------------------------------
To solve this you require a compiler that can compile the Groovy classes
independent of the Java class compilation. That requires reading representing
the Java sources as AST elements. I think that is at least a man-week (maybe a
month even) of somebody that knows what he is doing. What is missing, is
getting that time in a big enough chunk to allow for this implementation for
most people.
> Stub generation doesn't generate constructors added by @TupleConstructor
> ------------------------------------------------------------------------
>
> Key: GROOVY-6864
> URL: https://issues.apache.org/jira/browse/GROOVY-6864
> Project: Groovy
> Issue Type: Bug
> Components: Stub generator / Joint compiler
> Affects Versions: 2.3.2
> Reporter: Jan Bols
> Attachments: jointCompilationTest.zip
>
>
> When doing joint compilation, the generated subs don't include the
> constructors created by the {{@TupleConstructor}}.
> I created a groovy class:
> {code}
> @TupleConstructor
> class SomeGroovyClass {
> String someValue
> }
> {code}
> ... and a java class:
> {code}
> public class Client {
> public static void main(String [] args)
> {
> SomeGroovyClass groovyClass = new SomeGroovyClass("val");
> }
> }
> {code}
> When I build this in maven using the gmavenplus plugin I get the following
> output:
> {code}
> [ERROR] Failed to execute goal
> org.apache.maven.plugins:maven-compiler-plugin:2.5.1:compile
> (default-compile) on project jointCompilationTest: Compilation failure
> [ERROR]
> C:\dev\projects\jointCompilationTest\src\main\java\Client.java:[21,38] error:
> constructor SomeGroovyClass in class SomeGroovyClass cannot be applied to
> given types;
> {code}
> Looking at the generated stub shows that the constructor is not added:
> {code}
> @groovy.transform.TupleConstructor() public class SomeGroovyClass
> extends java.lang.Object implements
> groovy.lang.GroovyObject {
> public groovy.lang.MetaClass getMetaClass() { return
> (groovy.lang.MetaClass)null;}
> public void setMetaClass(groovy.lang.MetaClass mc) { }
> public java.lang.Object invokeMethod(java.lang.String method,
> java.lang.Object arguments) { return null;}
> public java.lang.Object getProperty(java.lang.String property) { return
> null;}
> public void setProperty(java.lang.String property, java.lang.Object value) {
> }
> public java.lang.String getSomeValue() { return (java.lang.String)null;}
> public void setSomeValue(java.lang.String value) { }
> }
> {code}
> You can find a sample project using maven in attachment.
