Gradle sync failed after deleting some files in gradle wrapper and cache. what should I do?

in Users/myName/.gradle/wrapper/dists
I deleted some files in this directory. the files are like this
gradle-5.x.x-all
because I thought I no longer need it and I just need the latest version. (i.e gradle-7.0.2-all )
and in Users/myName/.gradle/caches
in this directory, I also delete some files, and I delete 'old' file, only left 7.0.2
and when I open my android project, the gradle failed to sync, and I have this error
Deprecated Gradle features were used in this build, making it
incompatible with Gradle 7.0."
how to solve this issue? can I get that deleted file back? unfortunately I have deleted it from trash
I may delete more files, but unfortunately I forget. please help :(
I have tried to:
invalidate cache and restart
delete .gradle folder in my home directory
but I have this error now
Gradle sync failed: Sync failed: reason unknown
When I try to rebuild the project. I have this error
Unable to find Gradle tasks to build: [:].
Build mode: REBUILD.
Tests: None.

Android Studio: Unable to build app due to gradle distribution url error

I know this question has been asked before but I haven't been able to fix the issue. I am running Android Studio version 3.1.4. I am trying to run an app that I cloned from a Github repository. But even before I try to run it, I get this error:
my-app: sync failed
Cause: https://downloads.gradle.org/distributions-snapshots/gradle-4.4-20171031235950+0000-all.zip
How do I fix this error? Thanks in advance.

You can check and change the distribution url in the properties file $rootDir/gradle/wrapper/gradle-wrapper.properties. See property distributionUrl.
Value should be something as follows (update the gradle version depending on your Android Studio version)
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

I've encountered a similar error when I tried importing the Sunshine project from the Udacity Android development course. I fixed the issue by downloading the mentioned zip file and extracted it to the C:\Users\<username>\.gradle\native folder.
Then in Gradle settings, use local Gradle distribution and set the Gradle home path to the downloaded gradle folder.

You can fix it by the following steps: (currently using Android 3.6.3)
This worked for me.
Exit android studio then make the below changes.
Go to C:\Users\UserName.android and rename the build-cache folder to build-cache.bak.
Go to C:\Users\UserName.AndroidStudio3.6\system and rename these folders:
caches to caches.bak
compiler to compiler.bak
compile-server to compile-server.bak
conversion to conversion.bak
external_build_system to external_build_system.bak
frameworks to frameworks.bak
gradle to gradle.bak
resource_folder_cache to resource_folder_cache.bak
Open the Android Studio and open your project again.
If the folder is not in the Android3.6 folder, move to the next step.

Find the Gradle version from the gradle-wrapper.properties file
Download the Gradle bin file from internet, then extract it.
File menu-->Settings-->Build & Tools-->Gradle-->Use Gradle from: From
drop down select a specified location and browse to the location
where you have saved the Gradle bin zip file. (Default settings is use from ;gradle-wrapper.properties' file)
4.File menu-->Invalidate caches and re-run
[Gradle properties file]
[Gradle settings]

Android project building error - Symbol file with package cannot be empty

I have cloned an android project from gitlab. After building the project it shows the below error with build failed.
java.io.IOException: Internal error: Symbol file with package cannot be empty.
The project is okay on the other android studio from where it pushed to gitlab. what should I do to prevent this error. thanks in advance.

the solution that worked for me was to change the Gradle version from project structure.
in my case, I changed the version to match the local Gradle distribution I downloaded before and then going into Gradle setting in the project settings to check the use local Gradle distribution option of the same version.

Importing eclipse projects to android studio

I'm trying to import an eclipse project to android studio but keep getting the error message:
Gradle 'PhotoGallery' project refresh failed:
Error:C:\Users\user\.gradle\caches\2.14.1\scripts-remapped\settings_2yhllogm103q9sdcjkhbixdfg\9ejwtyixtds2dlx9q4hqm4iap\cp_settings57408229\cache.properties (The system cannot find the file specified)
I've already tried the below, but the problem persists:
File > Invalidate Caches/Restart > Invalidate and Restart
Here is a screenshot of the issue:

Removing .gradle directory should resolve your problem because android studio will recreate gradle directory without an error.

Android studio: Project refresh failed.. error in opening zip file

I've installed Android Studio on my laptop and also run the updates from 0.52 to 0.61
After creating a new project or opening a sample project that I've downloaded it displays this error:
Gradle '{ProjectName}' project refresh failed
Error:Cause: error in opening zip file
I couldn't find anything related to this specific error on Google or anywhere else on Stackoverflow.
Please help?

download manually
http://downloads.gradle.org/distributions/gradle-1.12-all.zip
and paste: (not unzipping)
C:\Users\ (USER NAME) \ .gradle\wrapper\dists\gradle-1.12-all[hash code]/
C:\Users\ (USER NAME) \ .gradle\wrapper\dists\gradle-1.12-all[hash code]/gradle-1.12-all.zip
update
For Mac OS X and Other Unix based OS, the path is
~/.gradle/wrapper/dists/gradle-1.x/[hash code]/

I had the same problem after updating Android Studio from 2.2.3 to 2.3; Here is the solution that worked for me:
1) In your project open 'gradle-wrapper.properties', change the 'distributionUrl' value
distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-all.zip
2) In you project open the project's 'build.gradle' file, and change the classpath
classpath 'com.android.tools.build:gradle:2.3.0'
This is the latest gradle setting.
Hope this work.
NOTE: The version of the gradle depends on your android studio version. So change the version(as in he code) according to that.

I fixed this issue by...
Going to Settings... > Gradle
Selecting "Use local Gradle distribution."
Pointed it to my Gradle zip file: home/kersting/.gradle/wrapper/dists/gradle-1.12-all/6vpvhqu0efs1fqmqr2decq1v12/gradle-1.12
It should be something similar for you if you downloaded Gradle which you should have when you downloaded Android Studio. Be careful, the .gradle file may be hidden. I found it through the terminal, but "ls" didn't reveal it.
