Unable to delete directory in Android Studio

问题:

Today I updated my Android Studio to 2.0 and when I run my project is gives me this error

Error:Execution failed for task ':app:clean'.
> Unable to delete directory: /media/dev1/08782A6D782A5A281/workspace/gengold/GenGold/app/build/intermediates/exploded-aar/com.android.support/appcompat-v7/21.0.3/jars

This is my build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"
    defaultConfig {
        applicationId "com.mobile.gengold"
        minSdkVersion 15
        targetSdkVersion 21
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
    }
}

dependencies {

    compile 'com.android.support:support-v4:21.0.2'
    compile 'com.android.support:appcompat-v7:21.0.3'
        /*compile 'com.google.android.gms:play-services-maps:6.5.+'*/
    compile 'com.google.android.gms:play-services:6.5.87'
    compile files('libs/jncryptor-1.2.0.jar')
}

I have deleted the jars from that directory but it shows the error repeatedly. Also it creates the directory again.

回答1:

I have exactly the same problem. The only temporary solution I've found is to exit Android Studio, delete the entire "build" folder (not only the jars), and then getting back to Android Studio to Build it.

The first build goes without errors or any warnings, but to rebuild again you need to follow the same steps as before :(

This is not a solution, obviously, but seems like the problem comes out from any service keeping occupied the files to be deleted in the "Clean" part of the rebuilding process.

EDIT:

It seems there is a problem with NTFS file system in android 2.0 Check out in https://code.google.com/p/android/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Status%20Priority%20Owner%20Summary%20Stars%20Reporter%20Opened&groupby=&sort=&id=206219

it works, i can run my project, but it will be showed again in the next running.

I'm using Android Studio 2.3.3 on windows, had the same problem, tried deleting the folder and got Access denied, rebooting my computer did not help either, for me the solution was : In Android Studio > File > Invalidate Caches / Restart...

回答4:

I noticed this started happening after I installed Tortoise SVN. I think installing it using a non-admin Windows account, might be the root of the issue.

回答5:

For me, rebooting my computer unlocked the locked file and solved the problem.

回答6:

After weeks of searching, I've found out that my Cloud-Sync-programs (I am using Tresorit, but same would apply to Dropbox or Google Drive aso) locked the files that AndroidStudio was trying to delete while uploading them to the cloud storage - and therefore making it impossible for AndroidStudio to delete the files.

On some cloud storage programs, you may use path filters - simply exclude the "build"-directories from your cloud storage (you usually dont need them backupped either way), or pause your cloud sync while working on the project.

Try to make the usage of the “file smash” function from tencent qq pc manager. The manager can unlock the file and then delete it.

Where to use it? After you install QQ pc manager, choose tool kits and install "file smash" tool. And then choose the file to delete, press right key of mouse and you find the function to unlock file and delete it.

That works for me. I guess other pc manager like qq manager may have this function too. That's all.
