Transitive runtime dependencies are part of compile configuration


(Nils Hendricks) #1

Gradle Version: 3.1
Operating System and JVM version: Windows 7
Is this a regression? If yes, which version of Gradle do you know it last worked for? No

If I declare a compile dependency (e.g. to io.reactivex:rxnetty:0.4.19) I see that gradle also puts all transitive runtime dependencies into the compile configuration (in this case for example io.reactivex:rxjava:1.0.17). Isnt this a bug? Can i configure gradle to be “scope-safe” and only put transitive compile dependencies into my compile scope?

Example:

apply plugin: 'java'

dependencies {
compile 'io.reactivex:rxnetty:0.4.19'
}

Here is the output of gradlew.bat dependencies --configuration compile

You could do this:

configurations {
   compileNonTrans { transitive = false } 
   compile.extendsFrom compileNonTrans
} 

dependencies {
   compileNonTrans 'io.reactivex:rxnetty:0.4.19'
}

I noticed that the OP referred to getting unexpected RUNTIME dependencies, not compile dependencies. That would truly be annoying, if transitive runtime dependencies resulted in compile dependencies. However, I just checked the latest POM for that main artifact, and “rxjava” is clearly a “compile” dependency, not “runtime”. I am looking at the latest version of it, 0.5.2, not 0.4.19, so it’s possible it used to be “runtime”, but that seems unlikely.

Guess I’ll shut up, then.

I guess you agree then that this looks like a bug? If i have code which needs classes from io.reactivex:rxjava it compiles with gradle but the compile fails if i try to compile it with maven (which is what i expected) …
