Questions: 1. Is it OK that I change all the

compile

to

implementation

(and

testCompile

to

testImplementation

)? Did I understand gradle output correctly with its deprecation warning? 2. What is the proper configuration to have library in B avaiable in A too? (if A is including B, and as we know from Gradle output,

compile

is deprecated) 3. Is there any place where I can read about currently supported configurations and what is the result of using them?

pawel.barszcz: it sounds like you want the

api

configuration

Would it be OK to have both

kotlin

and

java-library

applied? Is that plugin doing something more w/o applying `implementation`/`api` configuration or is just providing such configs (in other words: would it affect build somehow even without

api

configuration being used?) And, as I understand, it would be OK to use that

java-library

in all child projects of my whole project. I mean in all modules like

persistence

,

domain

,

http-client

etc. and to not use it in my two “end-side” projects:

runner

(Spring Boot) and

integration-tests

.

kotlin

and

java-library

should be good together (I haven't verified.it deeply yet) The

java-library

plugin is pretty thin https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/java/org/gradle/api/plugins/JavaLibraryPlugin.java
