Sep 15, 2010 With many problems, such as the infamous Red X issue, the common resolution is often to flush the local cache by completing the following steps: Go to the Visual Studio IDE folder in command prompt and Run the following command 'devenv /resetuserdata' from the Visual Studio IDE folder. Dec 06, 2017 Clear Visual Studio Component Cache It is a well known fact that the Component Cache may corrupt on extensions installations. It happens randomly and without any warning. While there are many ways to ask Visual Studio 'politely' to rebuild it, this is the rudest but guaranteed way to do it.
I’m trying to use Android Studio, and the first time I boot it up, it takes like 45 MINUTES to compile… If I don’t quit the application, it is okay – each subsequent compilation/running the app will take like 45 seconds.
I’ve tried to check some of my caches: there’s a .gradle/caches folder in my home directory, and it’s like 123 MB large.
There’s also a .gradle folder in my project folder… one of the taskArtifacts was like 200 MB. I’m scared to just randomly nuke them both. What parts of the folders are safe to delete?
Is there a better explanation for why my Android Studio is taking forever to run the gradle assemble task upon first time loading the application?
Do I also have to clear the intellij cache too?
You can safely delete the whole .gradle folder located under project directory. It’ll be recreated every time the tasks are run. The same is for .gradle under home directory. It’ll also be recreated as well, but the whole dependencies must be downloaded again – it’s quite time-consuming.
As I see in various places over the web gradle for android development is quite slow and people complain about it. No idea what’s reason exactly – this is how it works.

I don’t think that low performance is because of big folders. Actually they help it to be faster.
As @Bradford20000 pointed out in the comments, there might be a gradle.properties file as well as global gradle scripts located under $HOME/.gradle. In such case special attention must be paid when deleting the content of this directory.
The cache directory holds the Gradle build cache. So if you have any error about that you can delete that. It’s on .gradle/cache
You can do it on Android Studio
To clean out the system caches:
On the main menu, choose File Invalidate Caches/Restart. The
Invalidate Caches message appears informing you that the caches will
be invalidated and rebuilt on the next start. Use buttons in the
dialog to invalidate caches, restart IntelliJ IDEA or both.
Update: above method will clear Android Studio cache, not gradle cache. Gradle cache locates at
- On Windows: %USER_HOME%.gradle/caches
- On Mac/Unix: $HOME/.gradle/caches/
You can browse to these directory and manually delete it or run
on Unix system. Run this command will also force to download dependencies.
Update 2:Clear build cache of current project
On Windows:
On Mac or Linux:
newest solution using gradle task
cleanBuildCache
available via android plugin for Gradle, revision 2.3.0 (February 2017)
Dependencies:
- Gradle 3.3 or higher.
- Build Tools 25.0.0 or higher.

Build cache:
stores certain outputs that the Android plugin generates when building your project (such as unpackaged AARs and pre-dexed remote dependencies). Your clean builds are much faster while using the cache because the build system can simply reuse those cached files during subsequent builds, instead of recreating them. Projects using Android plugin 2.3.0 and higher use the build cache by default. To learn more, read Improve Build Speed with Build Cache.
Note: The cleanBuildCache task is not available if you disable the build cache.

Close the projects which are open inside android studio and just delete .gradle and
.Android(studio version) folders in root directory(for me c://users)
and start your android studio.
This worked for me, Thank you .
