DESCRIBE THE ISSUE IN DETAIL: The emulator CLI's -dns-server option does not seem to work on API 31 or newer.

STEPS TO REPRODUCE:

Run a local dns server and log queries: dnsmasq -dq
Start an API 31 emulator: emulator -avd emulator31 -dns-server 127.0.0.1
Resolve a domain: adb shell ping www.reddit.com
dnsmasq does not show that domain in the log.

However, on API 30, these same steps will result in the dnsmasq showing the queries to reddit.com:

dnsmasq: query[A] www.reddit.com from 127.0.0.1
dnsmasq: forwarded www.reddit.com to <ip>
dnsmasq: reply www.reddit.com is <CNAME>
dnsmasq: reply reddit.map.fastly.net is <ip>

We need to override some DNS entries in order to test our app in environments that do not have external internet access, but it stopped working in API 31 or newer.

I have tried the example project you've provided, it does not reproduce.

Could you please try running with -Pandroid.useDexArchive=false? This disables the new dexing pipeline, and fallbacks to the old one.

@Mario Did you get a chance to try the build with -Pandroid.useDexArchive=false flag?

Marked as fixed.

I'm the college of @Mario and I make it work without issues and without using -Pandroid.useDexArchive=false by using alpha6 and removing retrolambda

Sorry my comment from Apr 21, 2017 12:41PM was wrong.
With -Pandroid.useDexArchive=false it looks like this

:app:transformClassesWithDesugarForNonpayItalyCompatDebugAndroidTest
:app:transformClassesWithPreDexForNonpayItalyCompatDebugAndroidTest
Dex: warning: Ignoring InnerClasses attribute for an anonymous inner class
(org.ccil.cowan.tagsoup.Parser$1) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.

We updated our example repo

https://github.com/originx/Gradle_troubles_android_enteprise where you can see the issue.
Just run

./gradlew spoonGermanyDebugAndroidTest
or
./gradlew spoonGermanyDebugAndroidTest -Pandroid.useDexArchive=false

and you will see the issue

Your tests do not fit into a single dex file. I've tried plugin 2.3.0 (I've also had to enable retrolambda for app, core, and pay modules), and the number of references that are generated is higher than 64k.
Please note that if you are using plugin's internal or Retrolamba support for Java 8 language features, for each lambda expression you will generate 3 additional references, so it might affect your reference count quite significantly.
