How to generate a signed release APK with Gitlab CI/CD?

I am experimenting with GitLab's CI/CD and is figuring out how to generate a signed release APK.
I've read this article here.
and it suggested the following:
- ./gradlew assembleRelease
-Pandroid.injected.signing.store.file=$(pwd)/my.keystore
-Pandroid.injected.signing.store.password=$KEYSTORE_PASSWORD
-Pandroid.injected.signing.key.alias=$KEY_ALIAS
-Pandroid.injected.signing.key.password=$KEY_PASSWORD
and storing the variables at Gitlab CI/CD variables.
But everytime I run the pipeline it always results to this:
* What went wrong:
Execution failed for task ':app:packageRelease'.
> 1 exception was raised by workers:
java.lang.RuntimeException: java.lang.RuntimeException:
com.android.ide.common.signing.KeytoolException: Failed to read key key0 from store "/tmp/Lp7GrQLJ/0/XXXXX/sample-android-project/keystore": Keystore was tampered with, or password was incorrect
Can anyone please guide me here? What could I possible be doing wrong?

May this will helps you.

I have a problem to generate an APK in an android project through GitLab CI every time I run the gradle with the arguments assemble, assembleRelease or assembleDebug I get this error Task 'assemble' not found in root project 'MyProject'.

You have no variable ANDROID_SDK_TOOLS as used in the wget, you only have:
ANDROID_BUILD_TOOLS
ANDROID_COMPILE_SDK

Git lab pipeline Android project

I create an android project in git lab. I'm trying to use pipelines .
The build failed with message
Before building your project, you need to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager.
How can I accept this licences automatically?
Adding --no-ui --all is not enough (I have already tried to add them!).
I tried all the soluctions presented [here](you need to accept the license agreements and complete) with no success.
Does someone actually managed to make git lab pipelines works for android?
Below my .gitlab-ci.yml file.

The sdkmanager cli can be used to update sdks/ accept licenses.
To accept all licenses you can run
echo y | tools/bin/sdkmanager --licenses

I finnally resolve the problem using sdkmanager but I had to download the sdk zip instead of the tools zip like the code in my original question.
This is the final code I copied from Nick Petrovsky post on gitlab issue tracker
image: openjdk:8-jdk
variables:
ANDROID_COMPILE_SDK: "24"
ANDROID_BUILD_TOOLS: "25.0.3"
# ANDROID_SDK_TOOLS: "25.0.3"

before_script:
- mkdir $HOME/.android # For sdkmanager configs
- echo 'count=0' > $HOME/.android/repositories.cfg # Avoid warning
- wget --quiet --output-document=android-sdk.zip https://dl.google.com/android/repository/sdk-tools-linux-${ANDROID_SDK_TOOLS_REV}.zip
- mkdir $PWD/android-sdk-linux
- unzip -qq android-sdk.zip -d $PWD/android-sdk-linux
- export ANDROID_HOME=$PWD/android-sdk-linux
- export ANDROID_NDK_HOME=$ANDROID_HOME/ndk-bundle # Remove if you don't need NDK
- export PATH=$PATH:$ANDROID_HOME/platform-tools/:$ANDROID_NDK_HOME
- echo y | $ANDROID_HOME/tools/bin/sdkmanager --update
- echo y | $ANDROID_HOME/tools/bin/sdkmanager 'tools'
- echo y | $ANDROID_HOME/tools/bin/sdkmanager 'platform-tools'
- echo y | $ANDROID_HOME/tools/bin/sdkmanager 'build-tools;'$ANDROID_BUILD_TOOLS
- echo y | $ANDROID_HOME/tools/bin/sdkmanager 'platforms;android-'$ANDROID_COMPILE_SDK
- echo y | $ANDROID_HOME/tools/bin/sdkmanager 'extras;android;m2repository'
- echo y | $ANDROID_HOME/tools/bin/sdkmanager 'extras;google;google_play_services'
- echo y | $ANDROID_HOME/tools/bin/sdkmanager 'extras;google;m2repository'
- chmod +x ./gradlew

At the end I used this gitlab-ci-android docker image
It is faster and cause much less problems:
before_script:
- export GRADLE_USER_HOME=`pwd`/.gradle
- mkdir -p $GRADLE_USER_HOME
- chmod +x ./gradlew
cache:
paths:
- .gradle/wrapper
- .gradle/caches
build:
stage: build
script:
- ./gradlew assemble
test:
stage: test
script:
- ./gradlew check

I have created a CI image for Android, which can be found at https://gitlab.com/mvglasow/android-gitlab-ci.
It is based on what is described at https://about.gitlab.com/2018/10/24/setting-up-gitlab-ci-for-android-projects/, but it has all the Android tools in the image already so you don’t have to install them again for every CI run. Compared to the instructions, the image saves you about 30 seconds per pipeline.

How to accept android library licenses automatically from command line?

after executing this, I am getting this error:

How to accept ConstraintLayout 1.0.0-beta4 licence from command line?

in my case helped adding before_script: part:
- mkdir -p "${ANDROID_HOME}/licenses"
- echo -e "\n8933bad161af4178b1185d1a37fbf41ea5269c55" > "${ANDROID_HOME}/licenses/android-sdk-license"

- echo -e "\nd975f751698a77b662f1254ddbeed3901e976f5a" > "${ANDROID_HOME}/licenses/intel-android-extra-license"

Try while true; do echo "y"; sleep 1;done instead of echo y
