I don't believe the Soong transition is directly causing the increase -- in fact, as part of the transition we've enabled a number of optimizations. In addition to a growing codebase, the build has gotten more complicated, especially as Treble has been isolating the system and vendor partitions (and Soong has enabled some of this).
We expect most developers to be using incremental builds, which are far more reliable than they were a few years ago. On our CI systems, I saw the times roughly double between Lollipop and Pie, but incremental builds on average are faster than the Lollipop builds were (HW upgrades make it difficult to make comparisons over time though). Just interested, what are the units on the vertical axis? Seconds? - Dan On Fri, Dec 14, 2018 at 11:45 AM SZ Lee <skirio....@gmail.com> wrote: > Hi all > > > As the below picture shows the build time of aosp_arm64-eng on my build > machine, > > the full build time of Android Pie becomes longer than those of previous > versions. > > And latest master branch takes even longer time than pie release. > > > Could any one know the reason of the increase of the build time of aosp? > > Is it related with the build system change(make -> soong/bp) or is aosp > getting complex with more features? > > > > > [image: buildtime.png] > Thanks > > SZ > > -- > -- > You received this message because you are subscribed to the "Android > Building" mailing list. > To post to this group, send email to android-building@googlegroups.com > To unsubscribe from this group, send email to > android-building+unsubscr...@googlegroups.com > For more options, visit this group at > http://groups.google.com/group/android-building?hl=en > > --- > You received this message because you are subscribed to the Google Groups > "Android Building" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to android-building+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- -- You received this message because you are subscribed to the "Android Building" mailing list.
