Starting Gradle 5.3, 5.5 and 6.1, the

ObjectFactory

has factory method to create

[Named|Polymorphic]DomainObject(Set|List|Container)

(since 5.5/6.1) and

ConfigurableFileCollection

(since 5.3). That solve the issue around

DefaultDomainObjectCollectionFactory

and

DefaultFileCollectionFactory

. However, the code linked shows that you are creating more than just those two object. Essentially, you are building

PrebuiltLibrary

instances. I would recommend receiving the instance of

Repositories

via the Software Model so you can create your own

PrebuiltLibraries

and populate it as you want. However, I see the issue you are facing.

PrebuiltLibraries

implements

NamedDomainObjectSet

which means you need to create your own instance to add them to the set (instead of the container counter part where you can use

create

). The documentation further mislead because it shows you can create instance of

PrebuiltLibrary

via the Groovy magic offered by

NamedDomainObjectContainer

. In Java, you won’t be able to replicate because

PrebuiltLibraries

is a

NamedDomainObjectSet

. However the implementation of

PrebuiltLibraries

extends from

NamedDomainObjectContainer

. I believe it’s an oversight and you should be able to cast

PrebuiltLibraries

into

NamedDomainObjectContainer<PrebuiltLibrary>

without issue. Hence, creating prebuilt libraries would just be a matter of calling

create("…")

.

Thank you very much for the valuable information. I'll be in touch again to let you know how it went or to ask more questions. ;)
