Jetpack 2.1 book projects not workingfrom the CommonsWare Community archives

I am trying to do a rebuild of the Jetpack 2.1 project containing all the modules because I can’t CTRL+click on resources and stuff. However, trying that bumps me into a ton of errors, like:
Could not find androidx.core:core-ktx:1.3.5 (in the ToDoTests module)
Could not find androidx.lifecycle:lifecycle-extensions:2.3.1. (in the UnZipWork and DownloadWork modules)
and so on. If I comment these out eventually the synthetic view declarations don’t work anymore in all the modules.
Any way out of this?

androidx.lifecycle:lifecycle-extensions:2.2.0. For any others, use Google's Maven Repository or https://androidx.tech to find a version near the one the project is asking for.
I don’t know what happened here, but I will get it straightened out with Version 2.2, due out in a couple of weeks.

Done that, now it says “Unresolved reference: synthetic” with a long list of stuff that doesn’t work:
Unresolved reference: toolbar
Unresolved reference: about (the view that was solved by the synthetic mechanism that isn’t working)

Ah. For that, change
apply plugin: 'kotlin-parcelize' to
apply plugin: 'kotlin-android-extensions'. I moved all the projects over to view binding, but missed
At September 30, 2021, 10:35pm, Raptor replied:
I replaced “‘kotlin-parcelize’” in ~20 modules and now it builds, but the IDE still doesn’t color stuff differently (all the code is the same color) and CTRL+clicking on a view that points synthetically to its XML representation doesn’t work, it doesn’t do anything.
CTRL+clicking on “binding” doesn’t do anything, either.

What version of Android Studio are you using?
If it is Arctic Fox (or newer), and you have not done so already, consider allowing Studio to upgrade Gradle and the Android Gradle Plugin. For Version 2.2 (set for Arctic Fox), I also have
ext.kotlin_version set to
1.5.31 in the top-level

It’s Android Studio Arctic Fox | 2020.3.1 Patch 2
At September 30, 2021, 11:14pm, mmurphy replied:
Then, if you have not done so already, let Studio upgrade you:
classpath 'com.android.tools.build:gradle:7.0.2'in the top-level

They are already like that.

After invalidate caches/restart^^^
Sync, Rebuild after that changed nothing.

appcompat, make sure that you have the dependency.
databinding, Arctic Fox changed the syntax a bit, so you need to use
viewBinding true instead of
viewBinding = true in the module’s
More generally, you may just want to wait 10 days or so, when I have an Arctic Fox edition out and can figure out what went haywire with those dependencies.

OK, grab the current
master content from the GitLab repo. Everything in there builds and runs with Arctic Fox for me here, including from a fresh checkout of the code.

Did a pull, seems to work now. Thanks!
