Gradle project sync failed without Messages, worked on command-line

Question

In Android Studio, the sync failed:

Gradle project sync failed. Basic functionality (e.g. editing, debugging) will not work properly.

The command-line gradle installDebug worked. There were no messages in the "Messages" view. In the idea.log, the following NullPointerException appeared:

2018-02-04 14:53:15,234 [ thread 15]   INFO - e.project.sync.GradleSyncState - Gradle sync failed (4s 121ms)

Using Invalidate Caches/Restart and removing the .gradle folder did not help. Why is this? How is it fixed?

if you do this from the cmd prompt what happens and is installDebug one of the task? gradle tasks --all — Pomagranite, Feb 04 '18 at 14:14
@Pomagranite: yes, it is one of the tasks, it compiles successfully and wants to install to an emulator (which was not attached then). gradle tasks contains "installDebug - Installs the Debug build." — serv-inc, Feb 04 '18 at 14:39

After unsetting a local gradle distribution in Settings > Build, Execution, Deployment > Gradle (which was set for debugging this problem), Android Studio offered to update to gradle:3.0.1 from gradle:3.0.0. This fixed it.

Previous steps taken:

add the google() repository to buildscript and allprojects
upgrade the compileSdkVersion, and targetSdkVersion to 27
upgrade all com.android.support libraries to 26.1.0

I figured it was not your code causing the problem as the stack trace does not have any indication of the null belonging to your package. Thanks for posting the answer – Pomagranite Feb 05 '18 at 01:55

I was getting similar errors after I upgraded my Android Studio to 3.1.3. I don't remember the exact version I was on before that -- version 2 series.

The reason I was getting these errors was because the Gradle plugin version I was using was too low.

buildscript {
dependencies {
    classpath 'com.android.tools.build:gradle:2.2.3'
    ...
}

Once I updated the version from 2.2.3 to 2.3.3, then Android Studio was able to move on and give me more meaningful error messages such as

Gradle sync failed: Minimum supported Gradle version is 3.3. Current version is 2.14.1. If using the gradle wrapper, try editing the distributionUrl in gradle/wrapper/gradle-wrapper.properties to gradle-3.3-all.zip

From there, it's just a matter of resolving version compatibility issues.

For me, it was a simple solution: I had deleted a module from my project and forgot to delete it from settings.gradle

Maybe this can help somebody
