I don't know what should I do for this ...
I tried many ways but doesn't work with me until now ...

I think this question already exists, your key.properties file is probably the issue.
Execution failed for task ':app:validateSigningDebug'.
java.util.concurrent.ExecutionException:
com.android.builder.utils.SynchronizedFile$ActionExecutionException: java.io.IOException:
com.android.ide.common.signing.KeytoolExcepti
on: Failed to create keystore.
According to this gradle has failed to create the keystore file.this is probably due to your keystore.properties file missing. Have you signed your app? If not u can follow this guide here.

Error:com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details
see this link, Aapt2 is enabled by default to speed up builds.
Update your gradle version and this error should disappear, alternatively disable aapt2, but prefer to upgrade the gradle version, as just disabeling aapt2 hides the problem, and also slowes down your build.
updating
build.gradle(top level)
buildscript {
dependencies {
classpath 'com.android.tools.build:gradle:3.1.4
}
}
gradle-wrapper.properties
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip
alternatively disable it in gradle.properties
android.enableAapt2=false

Any sugestions what can be wrong?

This is happening because AAPT2 still has issues with long paths on windows (only supports paths up to 145 characters or so for now, sadly). This file path is around 170, so it's over that limit.
The issue should be fixed soon, in the meantime you can move your cache directory closer to the C: root.

I faced the same issue. The solution proposed here helped.
Simply add enviornmental variable GRADLE_USER_HOME
env GRADLE_USER_HOME= ${WORKSPACE}/gh
Note: Make sure gh is close to the main drive location
