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
groovy main.groovy someArg, then 1 will be printed
Could you, please, provide the correct main method order resolution?
