Help/Discuss
1

Hello ,
I m using toolingApi to manage gradle from java code , i wanna get my dependencies declared in my build.gradle without giving me the transitive dependencies ,

For example ;

for (ExternalDependency externalDependency : project.getClasspath())
      {
 }

here i have all my dependencies even which are not declared in my build.gradle .
if i have:

 dependencies {
compile  group: 'group.X', name: 'DependencyX' , version:  "11"
}

even if DependencyX have other dependencies i don’t wanna get it i just wanna get DependencyX.
Any idea how can i get the first level of dependencies from java using toolingApi
Thank you
