Georgii Ustinov updated GROOVY-11737:
-------------------------------------
    Description: 
Good afternoon
 
I am currently trying to support instance main methods inside IntelliJ IDEA 
groovy plugin as a part of Groovy 5 release, however, I can’t find any 
specification of how it works.
 
I have found that the feature was implemented here - 
[https://github.com/apache/groovy/pull/1910/files].
 
Looking into the source code - 
[https://github.com/paulk-asert/groovy/blob/90480bfade8c20f935311055e2ceb85288870605/src/main/java/groovy/lang/GroovyShell.java#L275]
 I can see the following order:
 
1) static void main(String[] args);
2) void main(String[] args);
3) static void main(args);
4) void main(args);
5) static void main();
6) void main();
 
The problem is that it doesn’t correspond to the reality.
 
Let’s consider the following code main.groovy
 
 
{code:java}
void main(args) {
println "1"
}
 
static void main() {
println "2"
}
{code}
 
 
If I run groovy main.groovy
 
1 will be printed (and it looks correct according to the semantics),
But if I change example:
 
 
{code:java}
void main(String[] args) {
println "1"
}
 
static void main() {
println "2"
}
{code}
2 will be printed (and thus the order in the code is violated). But if I run
 
Could you, please, provide the correct main method order resolution?
