Michael Vorburger commented on FINERACT-1198:
---------------------------------------------

[~aalmiray] but that's not primarly what we are after, here.. as described 
above, it would be neat if, ideally, the second {{./gradle bootJAR}} (WITHOUT 
clean; forget that) should not spend a full 1' minute to redo :compileJava and 
:spotlessJava and :resolve as it currently does - that seems wrong. And that's 
still the case even with --build-cache (which is expected; build caches don't 
solve that problem, but just rebuilding after a clean; which IMHO isn't the 
main problem in the Fineract project, but the fact that EVEN a rebuild WITHOUT 
clean doesn't seem to use the _task output caching_ right).. To illustrate 
again, check this out:
{code:bash}
$ ./gradlew clean
$ time ./gradlew bootJAR --build-cache
...
real    1m21.503s
user    0m1.474s
sys     0m0.152s

$ time ./gradlew bootJAR --build-cache
...
real    0m59.431s
user    0m1.368s
sys     0m0.121s{code}

>          Issue Type: Bug
>          Components: Build

> One of the reasons why Gradle is (supposedly) so much cooler than e.g. Maven 
> is that it can be really support and support very fast "incremental" builds 
> (only rebuild what has changed).
> I have the impression that doesn't really work in Fineract, and suppose 
> that's not really Gradle's (core) fault, but some plugin which screws this 
> up? OpenJPA Enhancer, SpotBugs... presumably they all have to "play along" 
> for this to work perfectly?
> My Gradle foo isn't (nearly) good enough to know if it would be possible to 
> "fix" this, and how hard this may be, but filing an issue is perhaps a start 
> for getting input from people more knowledgeable about this.
> [~aleks] and/or [~ptuomola] perhaps you have ideas about this.
> [~aalmiray] as per chat during ApacheCon, not sure if this is the kind of 
> thing you may enjoy helping with?
