Why aapt2 generate compile error "Check failed"?

I'm running AAPT2 from the command line:
%PATH_AAPT2%\aapt2.exe compile -v --dir res -o build
Many resource files are compiled. But after a time aapt2 is aborting with the message
Check failed: node_stack.size() == 1u
The build output is:
>C:\Android\aapt2\aapt2.exe compile -v --dir res -o build
res\color\button_back.xml: note: compiling XML.
...
res\drawable\rectangle.xml: note: compiling XML.
res\drawable\row.xml: note: compiling XML.
res\drawable\splash_screen.xml: note: compiling XML.
res\menu\menu_main.xml: note: compiling XML.
aapt2.exe F 08-23 07:52:20 16152 15008 ResourceParser.cpp:346] Check failed: node_stack.size() == 1u
What is the reason?
The used AAPT2 version is 4.1.0 rc01, but the error occurs with other versions too.
The error seems not to be related to any resource. I removed the recently compiled resources like menu_main.xml, but the error occurs furthermore.

Android - Copy build output to another folder with Gradle

I am trying to build my React Native Android app on Visual Studio App Center and I get this error:

It's incorrectly looking for my APK in the app/app/build/... instead of app/build/...So I want to copy the files to app/app/build/.. so it finds them there.
I can't copy the files with a post-build script because it runs after the script that throws the error.
Is it possible to somehow achieve copying with Gradle? Or maybe have multiple build paths? Or some other solution?

The problem was that I had gradlew, gradlew.bat and gradle folder in my appmodule folder. I must have mistakenly opened the app folder alone in Android Studio and synced the project.
I solved it by creating a fresh React Native project.

Execution failed for task generateJsonModelArmDebug

I try to use Android Studio to build native c++ project using cmake 3.14.0 version. Like in documentation: https://developer.android.com/studio/projects/add-native-code#use_a_custom_cmake_version . So I add version "3.14.0" to my build.gradle and add cmake.dir=C\:\\CMakeWin32 to my local.properties about vanilla cmake.
And then:
> Task :UnitTests:generateJsonModelArmDebug
> Task :UnitTests:generateJsonModelArmDebug FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':UnitTests:generateJsonModelArmDebug'.
> Illegal char <:> at index 47: C:/j/client/dava.framework/Programs/UnitTests\C:/r15c/sources/android/cpufeatures/cpu-features.c
If I use default cmake 3.6 in NDK bundle all works. My environment is:
Windows - 10
Android Studio - 3.4.1
gradle - try 4.10.1 and 5.4.1
ndk - try 15c and 19c
In my CMakeLists.txt I add dependency:
add_library( ${PROJECT_NAME} SHARED ${PLATFORM_ADDED_SRC} ${REMAINING_LIST} )
include(AndroidNdkModules)
android_ndk_import_module_cpufeatures()
target_link_libraries( ${PROJECT_NAME} cpufeatures)
I understand from error message full path to C:/r15c/sources/android/cpufeatures/cpu-features.c gradle want's to concatenate with path to current project C:/j/client/dava.framework/Programs/UnitTests. I think problem with gradle and how it use cmake_server to generate json code model. But how to fix it? Thanks in advance.
Update(more info):
If I build like: C:\j\client\dava.framework\Programs\UnitTests\Platforms\Android>gradlew :UnitTests:generateJsonModelArmDebug --info > log.txt 2>&1
in log file copy responce from cmake server and save it in file test.json
open test.json in Firefox and see target libcpufeatures.a in source section has full path to one source file.
sourceDirectory remainse from parent project C:/j/client/dava.framework/Programs/UnitTests
so I think gradle try to combine this two together bug in cmake or in gradle work with json responce from cmake.

Bug was in google gradle plugin so I just upgrade it and it works with new cmake 3.14.
Just update your gradle plugin:
dependencies { classpath 'com.android.tools.build:gradle:3.4.1' }

Migration of a project from Maven to gradle

I cannot perform the gradle init command in the directory of the project: the command line show this error :
gradle is not recognized as an internal or external command,
operable program or batch file
should I insert gradle as an environmental variable ? if so, how?

How to build apk using commandline

I Want to build apk using commandline, I am using ant server by using it I am building apk with commandline but when I give this command ant debug it shows error BUILD FAILED Unable to locate tools.jar and then it gives error source resource doesnt exist

This might be because your JAVA_HOME is not set to your C:\Program Files\Java\jdk folder.
instead it might be set to C:\Program Files\Java\jre so it's not getting tools.jar.
just check out this.
You can do this in this way:
C:\>set JAVA_HOME=C:\Program Files\Java\jdk
C:\>ant debug
You need tools.jar file from your jdk/lib/ folder.
