Hi thanks for your reply... I read the maven dependency mechanism and I understud how it's works...
The definition of 'provided' scope is that "is only available on the compilation and test classpath" and the user should provide the dependency at runtime. And the definition of 'runtime' scopoe is that "the dependency is not required for compilation" so my question is: why the provided transitive dependency is NOT included in 'compile' classpath and the 'runtime' transitive dependency IS included in the compile classpath? Furthermore IMHO this behavior could break some builds (see my little example) because if the project A needs B at compile time and the project B needs C at compile time.. for the 'transitivity' theorem also A might need of C at compile time, isn't it?. thanks ciao -- Marco Speranza <[email protected]> Google Code: http://code.google.com/u/marco.speranza79/ 2012/7/18 abhijith tn <[email protected]>: > Hi Marco, > > It is very simple.
