PS: You can also try to invalidate IntelliJ's caches (File \ Inavlidate
Caches) to see if that helps. That's what I did when I first encountered
my problem, but that takes quite some time (and looking back I cannot be
sure if it did not just work by accident, by basically waiting some time
between builds) so it is only a last resort.

Hi John,
I have bee using IntelliJ for years and have had a non-deterministic
build problem for about the same time span, where the Groovy compiler
throws on my code overriding a method in a child class with an
incompatible return type. Only my code is correct, and the problem
dissappears every time if I rebuild the project multiple times
(without any changes between builds). Afair IntelliJ introduced some
kind of caching mechanism to speed up Groovy builds some time back,
and I assume this is the cause of the problem.
So it might sound odd, but I would suggest you try rebuilding your
project multiple times in a row, with a little bit of delay between
builds, if possible through different build paths (e.g. build a
submodule other modules depend on first, etc), to see if the build
suddenly works in your case too.
Cheers,
mg

Hi,
This becomes problematic as the containing class is part of a much
larger system. I am building a a Groovy Parallel Patterns Library
and this is just one of the demos of the library I am working on. I
have had the code working in an Eclipse envrionment with an earlier
release of 2.4 probably around 10 or 11.
I have now moved to Intellij and this has thrown up the problem.
I will download a previous release of 2.4.n and see if I can get the
code to work and that may then help you to identify the problem.
I have been doing a major revision of my codebase moving from
Eclipse/Mercurial/ Bitbucket to Intellij/Github and this has thrown
up this problem.

Not sure what happened to the formatting - here it is again:
class QueensBase {
int N = 2
double doFitness(List <Integer> board) {
List <Integer> leftDiagonal = new ArrayList(2*N)
List <Integer> rightDiagonal = new ArrayList(2*N)
double sum = 0.0D
for ( i in 1 .. 2*N) {
leftDiagonal[i] = 0
rightDiagonal[i] = 0
}
for ( i in 1 .. N) {
leftDiagonal[i+board[i]-1]++
rightDiagonal[N-i+board[i]]++
}
for ( i in 1 .. ((2*N) - 1)) {
int counter = 0
if ( leftDiagonal[i] > 1)
counter += leftDiagonal[i] - 1
if ( rightDiagonal[i] > 1)
counter += rightDiagonal[i] - 1
sum += counter / (N - Math.abs(i-N))
}
// target fitness is 0.0
// sum can be negative so return absolute value
return Math.abs(sum)
}
}
println new QueensBase().doFitness(1..16)

QueensBase().doFitness(1..16)
It worked for me in the Groovy Web Console, Intellij IDEA
2017.3.5 pointing to 2.4.15, and the GroovyConsole for 2.4.15 and
2.3.0.
Perhaps we need a bigger sample to track down your issue.
Cheers, Paul.

Daniel,
Thanks for getting back to me so quickly.
I have converted to groovy2.4.15 and the same error occurs.
I am running under Intellij IDE and had downloaded the sdk
bundle.
