How to clear gradle cache

Question

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 around 45 seconds   I ve tried to check some of my caches  there s a  gradle caches folder in my home directory  and it s contains 123 MB   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

Take care with gradle daemon  you have to stop it before clear and re-run gradle   Stop first daemon     gradlew --stop   Clean cache using   rm -rf    gradle caches    Run again you compilation

there seems to be incorrect info posted here  some people report on how to clear the Android builder cache  with task cleanBuildCache  but do not seem to realize that said cache is independent of Gradle s build cache  AFAIK   my understanding is that Android s cache predates  and inspired  Gradle s  but i could be wrong  whether the Android builder will be was updated to use Gradle s cache and retire its own  i do not know   EDIT  the Android builder cache is obsolete and has been eliminated  the Android Gradle plugin now uses Gradle s build cache instead  to control this cache you must now interact with Gradle s generic cache infrastructure   TIP  search for Gradle s cache help online without mentioning the keyword  android  to get help for the currently relevant cache   EDIT 2  due to tir38 s question in a comment below  i am testing using an Android Gradle plugin v3 4 2 project  the gradle cache is enabled by org gradle caching true in gradle properties  i do a couple of clean build and the second time most tasks show FROM-CACHE as their status  showing that the cache is working   surprisingly  i have a cleanBuildCache gradle task and a  lt user-home gt   android build-cache 3 4 2  directory  both hinting the existence of an Android builder cache   i execute cleanBuildCache and the 3 4 2  directory is gone  next i do another clean build    nothing changed  most tasks show FROM-CACHE as their status and the build completed at cache-enabled speeds  the 3 4 2  directory is recreated  the 3 4 2  directory is empty  save for 2 hidden  zero length marker files     conclusions    caching of all normal Android builder tasks is handled by Gradle  executing cleanBuildCache does not clear or affect the build cache in any way  there is still an Android builder cache there  this could be vestigial code that the Android build team forgot to remove  or it could actually cache something strange that for whatever reason has not or cannot be ported to using the Gradle cache   the  cannot  option being highly improvable  IMHO     next  i disable the Gradle cache by removing org gradle caching true from gradle properties and i try a couple of clean build    the builds are slow  all tasks show their status as being executed and not cached or up to date  the 3 4 2  directory continues to be empty    more conclusions    there is no Android builder cache fallback for when the Gradle cache fails to hit  the Android builder cache  at least for common tasks  has indeed been eliminated as i stated before  the relevant android doc contains outdated info  in particular the cache is not enabled by default as stated there  and the Gradle cache has to be enabled manually    EDIT 3  user tir38 confirmed that the Android builder cache is obsolete and has been eliminated with this find  tir38 also created this issue  thanks

The gradle daemon also creates a many large text files of every single build log  They are stored here         gradle daemon X X daemon-XXXX out log    X X  is the gradle version in use  like  4 4   and  XXXX  are just random numbers  like  1234    The total size can grow to several hundred MB in just a few months  There is no way to disable the logging  and the files are not automatically deleted and they do not really need to be retained   But you can create a small gradle task to automatically delete them  and free up lots of disk space   Add this to your app build gradle   android        buildTypes                             Delete large build log files from    gradle daemon X X daemon-XXX out log        Source  https   discuss gradle org t gradle-daemon-produces-a-lot-of-logs 9905     def gradle   project getGradle       new File    gradle getGradleUserHomeDir   getAbsolutePath    daemon   gradle getGradleVersion      listFiles   each           if  it getName   endsWith   out log                     println  Deleting gradle log file   it      Optional debug output             it delete                       To see which files are being deleted  you can see the debug output in Android Studio -  View -  Tool Windows -  Build  Then press  Toggle View  button on that window to show the text output   Note that a Gradle Sync or any Gradle Build will trigger the file deletions   A better way would be to automatically move the files to the Trash Recycle Bin  or at least copy them to a Trash folder first  But I don t know how to do that

Gradle cache is located at  On Windows   USERPROFILE   gradle caches On Mac   UNIX     gradle caches   You can browse to these directory and manually delete it or run rm -rf  HOME  gradle caches   on UNIX system  Run this command will also force to download dependencies   UPDATE Clear the Android build cache of current project NOTE  Android Studio s File  gt  Invalidate Caches   Restart doesn t clear the Android build cache  so you ll have to clean it separately  On Windows  gradlew cleanBuildCache  On Mac or UNIX    gradlew cleanBuildCache

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  gradle caches directory holds the Gradle build cache  So if you have any error about build cache  you can delete it  The --no-build-cache option will run gradle without the build cache
