android - Error: File path too long on windows, keep below 240 characters

Question

So, I made some changes to my build.gradle(app) file and android studio gives me this error (open the image in new tab for better viewing):

My build.gradle(app) file (this is not the edited file, I deleted new lines of code and still no luck/solution.):

Everything was quite working well until I made some changes in the build.gradle(app) file, but then I deleted those new lines of codes and android studio is still keep giving me the error. The error relates to the compile 'com.google.android.gms:play-services:8.3.0'. I have tried deleting/renaming those png images inside the stated folder,but then when I rebuild the project, the png images are automatically downloaded. My build.gradle(project) file contains classpath 'com.android.tools.build:gradle:1.5.0'. I want to know what causes this error, and how to fix it? Many thanks.

Answer 1

You could also try changing your build directory for your project since that is where most of the path issues will arise. In your root build.gradle file

allprojects {
    buildDir = "C:/tmp/${rootProject.name}/${project.name}"
    repositories {
       ...
    }
}

Android Studio will pick up on the change and still show your new build location in the Project view. It's a lot easier than moving your entire project.

EDIT

While Windows 10 Insider Preview now offers the ability for allowing for longer file path limits these limits currently are only actually accessible to apps which have specifically enabled support for longer file paths.

At the current time, it appears that these applications with the extended path enabled seem to be only apps that are installed via the Windows Store.

At the current time, Gradle does not and potentially cannot have this option enabled to utilize the enhanced NTFS file path length.
