from one of my gradle projects, it seems that kotlin-stdlib-jre8 1.1.61 is dependent on kotlin-stdlib-jre7 1.1.51, and also kotlin-stdlib-jre7 1.1.61 is dependent on kotlin-stdlib 1.1.51. so in order to use 1.1.61 for all of them, i have to write 3 lines instead of just one line. is this intentional?
