Hello Groovy users
I am looking for help in setting up my class loaders with the Groovy
compiler. This is my understanding so far
1. The compiler is an external tool to compile (Groovy is a java based
compiler) and therefore it must have its own class paths and a class loader
to load lib

Hello Groovy users
What is the right way to define this java annotation in groovy? I am
testing this out in Groovy 5.0, I have not tried 4.x.
I tried using [] after the default keyword, but I get the error

Hello there
I am compiling standard Java code with Groovy (it works for the most part
with some exceptions) and want to call out some differences. Is there a way
for me to auto fix these discrepancies with say a text pre-processor or
some AST parsing modifications?

Hello folks

of mutable and immutable objects. Java lets me hold mutable objects in
immutable object lists (as per the code below). But my DSL also wants to
allow immutable objects to be held in mutable lists. The meaning it

Hello Groovy users
I am using Groovy 3.0.5
- I have a file A.groovy and B.groovy. B depends on A
- I have ast transformations that add annotations to methods in A
(specifically an annotation with a list expression that contains other
annotations)
- I compile A.groovy using the load

Hello all,
I am trying to do two things
1) Extract comments from inside a function code (not the function's groovy doc,
but comments embedded inside the function code itself)
2) Extract the source code of the function itself
For example
/* Comments about myFunction *./
void myFunction() {

I am using Groovy 3.0.5 and it supports multiple assignment statements from

def(var1, var2) = Tuple.tuple("a", 1)

Also it defaults to identifying var1 and var2 as objects. Thi
Hello,
I am using a closure inside an annotation over an interface method. I then
decompile the class in intellij (open the .class file essentially) and I see
that the closure class was created, but I dont see the class definition
anywhere. I am however able to access it in code. Is this a limi
better approach.

I have a requirement where I load all my groovy files into a remote
database. I then have to pull them down to compile and I am wondering what
is the best way to do this. Right now I do this
* I pull down the names of all files (not the actual file)
* I then use a GroovyClassLoader to load
