Hello. I am having some difficulty using composite builds. I have a multiproject (called "framework") which I have included in another project, using

includeBuild

. Inside the nested project, I have a number of subprojects, for example "web" and "security". I also have a "meta" subproject, which declares all the other subprojects as dependencies. My issue is that if any of the subprojects have an external dependency declared with

api

, for example

api("org.springframework.boot:spring-boot-starter-security")

, then the whole nested multiproject fails to build with

> Could not find org.springframework.boot:spring-boot-starter-security:.
     Required by:
         project :framework:meta > project :framework:security

When working with the "framework" project directory, i.e. without

includeBuild

, it works fine. If I declare the dependencies as

implementation

instead of

api

, it works fine, but then of course I have to declare the dependencies in depending subprojects. Any help would be appreciated, because at this point I'm really out of ideas, and feel like I will have to scrap the whole idea of having the "framework" be a multiproject.

Are you using the Spring dependency management plugin?

I am, though should note that this isn't limited to Spring. I get the same error if I add any other dependency.

You should stop using it. It is a relict from times when Gradle did not have built-in BOM support. By now it does more harm than good. Even its maintainer recommends not to use it anymore, but the built-in BOM support using

platform(...)

. This will most probably also solve your problems, as they are one of the many drawbacks you earn by using it.
