Android Studio - Gradle sync failed: Already dispo

问题:

After updating to Android Studio 3.2 Beta 1, I started getting the following error for two different projects:

Gradle sync failed: Already disposed!

There is no error with Android Studio 3.1.3, and there was no error with various canary versions of Android Studio 3.2 before updating to beta 1.

I already tried everything I can think of (e.g. complete cleaning of project, including all generated .gradle/.iml/.idea files/folders, as well as a complete invalidate cache and restart of Android Studio) without success. The build works as expected from command line using Gradle.

This is not a duplicate of Android Studio Gradle Already disposed Module

EDIT

The event log is showing

Unable to save plugin settings: The plugin org.jetbrains.android failed to save settings and has been disabled. Please restart Android Studio

In the "IDE Fatal Errors" window, I am seeing the following exception:

EDIT2:

More recent version of Android Studio 3.2 are having the same issue.

回答1:

As it turned out, the problem was that I was trying to open a project directory that was a symlink to the actual location (on the same partition). Gradle (on command line) had no issues building the project from the symlinked location, however, opening it in Android Studio resulted in the obscure and non helpful error described above.

Simple solution

    1.Delete module folder and modules.xml file under .idea folder. 
    2.Close Android Studio
    3.Reopen and sync

Possible duplicate problem:

This worked for me: Delete the .idea folder.

1) Go to File--> Settings -->Plugins Disable any plugins not loaded (i.e. red in color) @friederbluemle This may not apply to you.

2) Enable the one plugin, Android Support

3) Right-click on your 'app' directory (contains your module gradle.build file) in Android Studio and select 'Show in Explorer' --- this opens that directory.

4) Quit Android Studio. Get out of any and all instances of Android Studio to allow you to then delete the fold, .idea, in that directory.

5) Restart AS, you'll notice the project will not come up -- you'll have to pick in the dialog window that appears. That's ok. Pick it, and it will 'rebuild' the folder, .idea.

6) Go to File--> Settings -->Plugins Enable any and all plugins if any.

What worked for me was going to Android Studio File and Invalidate/Restart options.

回答5:

What worked for me is as follows

1. Delete the .idea folder
2. Close Android Studio
3. Reopen Android Studio and allow it sync your project all over.
