okay here's very lightweight solution with steps:

<li>Select Project from left panel</li>
<li>Now check your Gradle Version at right panel</li>
<li>In my case my Gradle Version is 3.3</li>
<li>Navigate C:\Users\ashish\.gradle\caches and delete your Gradle Version - 3.3 named folder.</li>
<li>Now restart or open your project again from workspace.</li>
</ul>

Greetings...your problem is solved.

Deleting cache folder take long time because it have more than 200k files which is more than 3GB. There is quick view as Ashish mentioned.

I also faced this error in only one app. 

Go through the step.

<ol>
<li>In you project open <code>gradle-wrapper.properties</code> file. Which is located in Gradle Script in Android structure. As shown in below image.

<a href="https://i.stack.imgur.com/dyNxj.png" rel="noreferrer"><img src="https://i.stack.imgur.com/dyNxj.png" alt="enter image description here"></a></li>
<li>In that file check <code>distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip</code>. Here gradle version is 4.6.</li>
</ol>

<a href="https://i.stack.imgur.com/URhmz.png" rel="noreferrer"><img src="https://i.stack.imgur.com/URhmz.png" alt="enter image description here"></a>

3.So all cache for that project will be store in your <code>C:\Users\Your PC Name or User Name\.gradle\caches\4.6</code>. As shown in below image.

<a href="https://i.stack.imgur.com/8JRIL.png" rel="noreferrer"><img src="https://i.stack.imgur.com/8JRIL.png" alt="enter image description here"></a>

<ol start="4">
<li>Close your android studio and delete the 4.6 folder. After deletion open android studio.</li>
</ol>

That's all. It took mine 6 hours to figure out and deleting cache folder. So I decide to post this answer. So people will not waste same time.

blocks|key|1570857|text|在android+studio中，单击“无效缓存/重新启动..”并确认。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1570858|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I had the same problem.
And deleting the project's .gradle folder didn't fix the problem.

I solved the problem by deleting the <code>C:\Users\&lt;username&gt;\.gradle</code> folder and made studio refresh the entire gradle build. I found I had 4 different versions of gradle installed from my upgrade path.

I faced the same problem in Android Studio 4.0.1 when my computer froze and I had to force shut down.
What I did to resolve the issue was delete .gradle folder from the project directory and build the project again.
<ol>
<li>Open the Project pane, if not open already.</li>
<li>Select the Project view (not Android) from the drop-down menu</li>
<li>The first folder (in red colour) will be .gradle, Right Click &gt; Delete.</li>
<li>Build the project again.</li>

None of the above worked for me ....

You just need to go to File -> Project Structure or jus press Ctrl+Alt+Shift+S

and then on the top left click Project Make sure that your Android Plugin Version is the same as you Android Studio Version .. This should fix it 

additionally 

You can also create a new Project and check under Project view initially you'll be in Android .. change the view to ... Project - > gradle (Note .. not .gradle only gradle ) ->wrapper ->gradle-wrapper properties.. open this file and you can see the last line ie ..

<pre><code>distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip
</code></pre>

make sure you have the same gradle version in your old files as well

-
Go into your local file project and search for the ".gradle" folder,(folder from user directory, not from project, it`s a hidden directory, if you used linux-based system it is in /home/user/.gradle and press "alt"+"." to show hidden folders,) 

<ul>
<li>Erase it and restart your IDE</li>
</ul>

if this doesnt work then,
All of these solutions did not work for me on Android Studio 2.1. What worked was me opening gradle-wrapper.properties in project folder and changing my gradle reference on the line below:

<pre><code>distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip

This was changed to:

For the persons who have this problem on &lt;Android Studio 3.1.2>.
After I got this problem, I done all solutions in this topic. But each of the solutions alone did not solve my problem.
So I've combined some strategies.

<hr>

<ol>
<li>First I removed application from Android Studio Launcher List.</li>
<li>Second I deleted all the content from .gradle (FOLDER FROM USER
DIRECTORY).</li>
<li>Third I import the project again (after sync i got the error
again).</li>
<li>Fourth while project is open I used &lt;Invalidate Cache / Restart>
option from FILE menu.</li>
</ol>

<hr>

I hope this solution work for you too.

Removing the <code>.gradle</code> directory from the user directory is not enough. Make sure to delete the <code>.gradle</code> directory from the project directory as well. In fact I would start with the project and only if that isn't enough should you delete at the user level.

I found a root cause of this problem for my case under Ubuntu 16.04. Both .gradle and project directories should have proper permissions. I've created this directories by myself and that's why they had more restricted permissions.

In my case, none of the previous answers worked for me. The solution was to delete the entire gradle folder (not the .gradle folder inside the project) and replaced it with a gradle folder backup, independenly where it's located in the operative system.
I had tried deleting only the cache folder but the problem persisted maybe because I was using a customized gradle folder provided from my job.
I do not recommend this solution in general but if none of the others works, then replace the complete gradle directory or reinstall could be a solution.

If this error occurs while you are trying to run an app on your mobile device via phone USB, make sure the compiled compileSdkVersion and buildToolsVersion are up to date, if they are, just uninstall the app in your phone and run the app again.

After upgrading Android Studio to 1.3, I can't compile my project anymore. I am getting <code>Unexpected lock protocol found in lock file. Expected 3, found 0.</code>. I have tried with deleting my <code>.gradle</code> folder but that does not solve the problem. Anything else I can do?
