Gradle Sync Fails With "UnhandledIsstesReporter"

Question

Here's an issue I had after Android Studio Upgrade From 3.4 to 3.5. A previously working project now fails with the following error:

Gradle sync failed: com/android/tools/idea/gradle/project/sync/issues/UnhandledIssuesReporter (wrong name: com/android/tools/idea/gradle/project/sync/issues/UnhandledIsstesReporter)

Error Log Exception:

I updated the gradle plugin version from 3.4.2 to 3.5.0 in my project's gradle file:

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

I then got another error:

Gradle sync failed: Minimum supported Gradle version is 5.4.1. Current version is 5.1.1. If using the gradle wrapper, try editing the distributionUrl in ...\StudioProjects\BlueView\gradle\wrapper\gradle-wrapper.properties to gradle-5.4.1-all.zip

So I did what it suggested and modified my gradle-wrapper.properties files to:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-all.zip

I synced project with the gradle files and after the new version of gradle had been downloaded, It failed again with the very same error:

Gradle sync failed: com/android/tools/idea/gradle/project/sync/issues/UnhandledIssuesReporter (wrong name: com/android/tools/idea/gradle/project/sync/issues/UnhandledIsstesReporter)

I invalidated cache and restarted Android Studio. Still No Luck.

Finally, I tried creating a brand new project. Build also failed on the brand new project template.

I searched my hard drive for this mysterious UnhandledIsstesReporter file and didn't find it.

Answer 1

The fix is to export your settings, remove Android Studio and reinstall.

Export your settings

Uninstall Android Studio

Normally, you should be able to uninstall it from Windows Settings.

I couldn't find Android studio in Window's remove list so I ran C:\Program Files\Android\Android Studio\uninstall.exe

Delete remaining Android Studio files

deleted the following:

• C:\Users\<User>\.AndroidStudio3.5\
• C:\Users\<User>\.Android\
• C:\Users\<User>\.gradle\

Reinstall Android Studio

I reinstalled Android Studio and it works now.

Import the settings you previously backed up

I imported the settings I saved before uninstalling and it still works.

Answer 2

Don't uninstall anything, its hard to install all these again. i also face the same problem , i just delete my emulator from AVD and pick another and then go to project structure change the API your prefer to use. and if you have two API or SDK installed then remove tick from the useless one's from the sdk manager.

Answer 3

First, PLEASE MAKE SURE THAT YOU DON'T MIND OVERWRITING YOUR WORK or have saved it somewhere.

Then run:

git reset --hard origin master

(or whatever it's called), in my case it was:

git reset --hard origin develop

Also, this is how I solved my problem. Your problem may have a different solution.

Here are a few other potential solutions to your problem. You may try it in any order you want though:

2. Build -> Clean Project
3. Remove emulator as Owais mentioned.
4. Restart Android Studio
5. File -> Sync Project with Gradle Files
6. File -> Sync with System files
7. File -> invalidate Caches/Restart... -> Invalidate and Restart. It usually takes 10 to 30 minutes but solves a lot of similar problems (not this one in my case though).
8. Uninstall Android Studio and install it again as Jon mentioned.

Answer 4

For me it was enough to execute the clean and build tasks of gradle to clean that error.
