how do i get more information from a cmake failure in android studio?

android studio 2021.2.1 on win10pro
i just moved to a new machine, and just did a "git clone" to pull my project. when i try to build it i get the error message below.
it appears cmake is failing, but there is no indication of WHY it is failing. i looked at all the various files and paths handed to cmake, and they all appear to exist.
how do i get cmake to give me more information about what has gone wrong?

the android tensorflow demo build error with bazel command

when i run the tensorflow android demo.
i have installed the bazel for a long time to build the environment.
and then when all tool is done.then run the demo in Android Studio.
the gradle console show me this:
the error image
and the error occured when the task of buildNative executed.
the full command line display in the gradle console:

Did you build native libs with these commands?
CPU=armeabi-v7a

Tensorflow cannot see the path to the NDK. You need to update the WORKSPACE file in the projects root folder with the NDK and sdk paths. you also need to install the correct NDK for your machine. Follow the instructions here

check if it helps

Compile your project in https://build.phonegap.com/
There you have no problems with OS and can compile for all OS.
I use then for IOS compilation.

Solution:
Uninstall node v0.10.25
install node 0.12 or above
remove platform android (cordova platform rm android)
add platform android (cordova platform add android)
build android (cordova build android)
Done

thanks.

You can try this
Go to this directory
C:\Users\Mohammad\.cordova\lib\npm_cache\cordova-android\3.6.4\package\framework
Edit project.properties file. Change target to 19.

Restart your terminal.

You don't have SDK correctly installed on you computer. (Path or SDK update)
It's write on your error log : You may not have the required environment or OS to build this project

you just need to install ant
sudo apt-get install ant
then do the same as before,its work correctly

Build Android project on command line on OSX: Task 'assembleDebug' not found in root project

I'm trying to build Android projects on the OSX (Mavericks 10.9.5) command line using this how-to: http://developer.android.com/tools/building/building-cmdline.html.
This How-To explains the use of assembleDebug/assembleRelease to build an Android project.
Unfortunately gradle doesn't create the assembleDebug or assembleRelease targets.
Executing ./gradlew assembleDebug returns this:
FAILURE: Build failed with an exception.
* What went wrong:
Task 'assembleDebug' not found in root project 'test'.
* Try:
Run gradlew tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

What am I missing to be able to build an Android project on the command line?

android create project does not create a gradle friendly structure. It creates an ant friendly structure. You have two options depending on your intentions.
use ant to build your project ( not currently supported by Android team )
use Android Studio to generate a gradle friendly project structure.
num 2 is the recommended approach by the Android team. It's as simple as dl'ing Android Studio and creating a new project. From there you should be able to create a new project that can be built with ./gradlew build

try This:
./android create project -p AppPAKTGV -a Main -k com.example.apppaktgv -t android-23 -g -v 0.11.+
it's works but when i try target 24 or 25 not work i don't now

Try to do this and note
a) you need to type tools/android under Step 3 (like step 2: Execute)
-- but as said the ant structure is not helpful
-- not sure I can go from there
b) I follow the advice and also ensure get the platform-tools
-- I can build
-- I can get that .apk
-- I can adb install (I rename any existing .apk)
Seems working!
