Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)

Question

I am getting this kind of error, how to fix it.

Error:Unable to load class 'org.gradle.tooling.internal.protocol.test.InternalTestExecutionConnection'.
Possible causes for this unexpected error Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
Stop Gradle build processes (requires restart)Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

Answer 1

I updated my Android Studio to 2.3 and it asked me to update my gradle plugin to 3.3 that created issues with my running projects. I've gone through all the Stack solutions and nothing worked for me except this workaround: I changed my distribution url in gradle-wrapper.properties with this one.

distributionUrl=https\://services.gradle.org/distributions/gradle-3.4.1-all.zip

My project is up and running.It just asked me to update to gradle build tools 25.0.0 which I did so. Everything is fine now :)

1. Go to the project section and select gradle scripts menu.
2. Under script, menu select gradle -wrapper.properties
3. Then replace the distributionUrl=https://services.gradle.org/distributions/gradle-2.2-all.zip with "distributionUrl=https://services.gradle.org/distributions/gradle-3.4.1-all.zip"

note: distributions gradle will change depended upon the version of the android studio.

Make sure you have Internet Connection then:

1.For Window Users Go to > C:\Users\username\.gradle\wrapper\dists

2.For Linux users Go to $HOME/.gradle (~/.gradle) and/or (Under Specific project) <PROJECT_DIR>/.gradle

3.Delete the gradle file(s) with the problem(i.e the zipped folders with missing with no its extracted file )

4.Sync the project with gradle files.

Answer 5

If you manually setup gradle also make sure projects build.gradle verison is compatible with it. See following as an example.

Project's build.gradle

dependencies {
        classpath 'com.android.tools.build:gradle:2.3.2'
    }

Manual gradle setup

Answer 6

Delete corrupt files

This error occurs when Gradle files are not completely downloaded or corrupted by some other reason, so we have to redownload the files. The easy way is to delete the old files in

C:\Users\username.gradle\wrapper\dists

and rebuild the project, Android Studio will automatically download the new files.

Answer 7

Try the next step to "Refresh" your IDE (android studio)

1. Let Gradle rebuild your auto-genrated files by click Build | Rebuild
2. Also try Choose File | Invalidate Caches/Restart.

Answer 8

I resolved this issue by downloading current version of graddle from link given download latest version of graddle possibly graddle 3.3

Then in next step i accessed .graddle/wrapper/dists dirctory from home directory on my Mac after showing up hidden system files and deleted previuos version folder residing there.

Now i put that downloaded latest version folder after uncompressing there. Now restarted Android studio and problem was resolved.

Answer 9

check out distributionUrl setting in gradle-wrapper.properties. I changed https to http, then my problem was solved.

Answer 10

You can try this

1. first Open your Android Studio > open any project you're doing
2. click on File > Settings > Build,Execution,Deployment > Gradle
3. At Project-Level settings , there are 2 option to sync the gradle either usin the default or local.

4. now change from default to a local gradle distribution > gradle Home

5. select the path on your computer.

C:\Program Files\Android\Android Studio\gradle\gradle-4.1

6. click on OK

7. Now build starts again it should be solved.

Answer 11

In my case,just change http to https in the gradle-wrapper and Sync it.

Answer 12

Just reimport project. :) I tried cleaning up the cache and refreshing dependencies doesn't work but failed.

Answer 13

Clear .gradle folder and rebuild

Answer 14

Finally solved this problem.

If you just copy new version's files to old folder and override files,you may face the same question as me.

To solve it:

1. makesure you saved your all settings.
2. close AS,DELETE ALL files of your mixed version.
3. extract new version to your empty folder.

It works for me.

Answer 15

If you have updated your android studio, then go to FILE, Project Structure, Project, then check gradle version. Before that check your gradle version in C:\Program Files\Android\Android Studio\gradle and check the version if it matches then sync again else change the gradle version in android studio and sync again.

Answer 16

I had a similar problem after cloning AnySoftKeyboard and opening it in Android Studio. What worked for me was deleting the AynSoftKeyboard/gradle folder and then cleaning the project via menu item Build > Clean Project.

So try deleting YourProject/gradle folder and clean the project to trigger a Gradle sync.

Hope it works for your case.

Answer 17

download gradle from here for your OS and extract the file and paste the inner folder into installLocation/gradle

than in Android Studio Goto File > Settings > bulid ,exec,deployment > gradle and choose local gradle option and provide the file path of your new downloaded gradle and hit ok it works :)

Answer 18

1. delete C:\Users\Administrator.gradle\caches\xxx (xxx gradle version)
2. rebuild

Answer 19

I had this problem i just deleted every thing related to android in c://user/your pc name / and it worked

Answer 20

If it has happened after upgrading Android Studio, It can be caused by an out of date buildtool, Update Android SDK BuildTools

Answer 21

1. Open C:\Users\Username.gradle\wrapper\dists\

2. Open latest gradle folder, e.g. gradle-4.1-rc-1-all

   You will find a random folder named 936kh1brdchce6fvd2c1o8t8x

3. Download zip file of similar name

   eg: https://downloads.gradle.org/distributions/gradle-4.1-rc-1-all.zip

4. Save it in this folder

5. Restart Android studio

   It will automatically extract the zip folder and Error will clear

Answer 22

For Mac users

1. open /Users/username/.gradle/wrapper/dists
2. Check the latest gradle-4.4-all inside that directory
3. Use the latest version and put it to gradle-wrapper.properties in Android Studio Project

In my case i was using distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip that is why I get the issue.

I change it to distributionUrl=https://services.gradle.org/distributions/gradle-4.4-all.zip and just sync again

Hope this will help.

thanks

Answer 23

Sometime problem is gradle wrapper file inside your project file. Open your current project gradle file and delete gradle wrapper.zip file and then sync project this will work.

Answer 24

Maybe you can run ./gradlew build -s in the terminal, the stacktrace would show you where went wrong.

Answer 25

This was my scenary: I had to use another Android Studio version (3.2.1) and the Gradle version was 4.6. For that, I downloaded the .zip version of Android Studio. At first it didn't work, even if I created a new project, Gradle wasn't working. But after some research and some help from this posts I did the following:

1. I went to my gradle files route (android-studio\gradle) and deleted all the gradle-4.6 files.
2. After that I went to gradle-wrapper.properties and got the Gradle version that I needed (gradle-4.6-all.zip).
3. I went to the gradle site and look for the version that I needed.
4. Downloaded and unziped it into my Android Studio's gradle file route, look step 1.
5. I went to Android Studio settings (file/settings/Gradle) and change the option "Use default gradle wrapper (recommended)" to "Use local gradle distribution".
6. I selected the route where I downloaded the Gradle version, that's step 4, and applied changes.
7. Just in case, I used the "Invalidate Cache / Restart" option (file/ "Invalidate Cache / Restart").
8. After that I used the "Sync project and Gradle files" and worked!

By the way, I am using Android Studio 3.2.1 zip version. I had the same problem when I tried to create projects with older Android Studio.
