Android Studio - Gradle sync error on gradle-diagn

问题:

I've just updated Android Studio and I can't sync my project anymore.

The event log reports:

Gradle sync failed: /Applications/Android Studio.app/Contents/gradle/gradle-X.X.X/lib/plugins/gradle-diagnostics-X.X.X.jar (No such file or directory)

To solve the Gradle sync error, open gradle-wrapper.properties file and update the Gradle wrapper distribution version from:

distributionUrl=https\://services.gradle.org/distributions/gradle-X.X.X-all.zip

To:

• Android Studio 2.3 distributionUrl=https\://services.gradle.org/distributions/gradle-2.3-all.zip
• Android Studio 2.2 distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip
• Android Studio 2.1 distributionUrl=https\://services.gradle.org/distributions/gradle-2.12-all.zip
• Android Studio 2.0 distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip
• Android Studio 1.5 distributionUrl=https\://services.gradle.org/distributions/gradle-2.8-all.zip
• Android Studio 1.3 distributionUrl=https\://services.gradle.org/distributions/gradle-2.4-all.zip

You can find the latest Gradle wrapper version visiting: https://services.gradle.org/distributions/

EDIT:
As a side note, as @SeBsZ suggests, the official repository of the Android Gradle plugin switched from MavenCentral to jCenter (see Bintray blog post).

Make sure your project build.gradle file contains the new repository and the new classpath:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

This is not strictly related to the question problem, but since we are already migrating to the new IDE preview it's better to make sure everything is in place.

If, like me, you are using an older project then you might still be using the maven repository. Make sure you change the repositories in your top-level build.gradle from maven() to jcenter(). Then make sure you are using the correct dependency as well: classpath 'com.android.tools.build:gradle:1.3.0-beta1' for the new 1.3 preview.

For me helped to set chmod on the .gradle directory to 777. After this whole Android studio started working correctly.

回答4:

This is the weirdest thing ever and I never expected it to work but this:

distributionUrl=https://services.gradle.org/distributions/gradle-2.2.1-all.zip

worked and got everything fixed (it was the '\' after https). It does make sense since that is an actual link to a file.

回答5:

check your .bash_profile file and make sure your GRADLE_HOME points to a valid path, if things were working and you face this issue after android studio update, chances are your gradle got updated too. Here is the example of my gradle home in .bash_profile: export GRADLE_HOME=/Applications/Android\ Studio.app/Contents/gradle/gradle-2.14.1/bin

Had the same problem with a newly set up Android Studio 2.2.2, gradle wrapper 2.14.1. I loaded the project before i installed the needed android-23 library and installed java after Android Studio installation.

Error message in Android Studio 2.2.2:

Error:The specified Gradle distribution
'https://services.gradle.org/distributions/gradle-2.14.1-all.zip' does 
not appear to contain a Gradle distribution.

Error message in cmd:

projectfolder> gradlew
Exception in thread "main" java.lang.NullPointerException
at org.gradle.wrapper.BootstrapMainStarter.findLauncherJar(BootstrapMainStarter.java:34) 
at org.gradle.wrapper.BootstrapMainStarter.start(BootstrapMainStarter.java:25)
at org.gradle.wrapper.WrapperExecutor.execute(WrapperExecutor.java:129)
at org.gradle.wrapper.GradleWrapperMain.main(GradleWrapperMain.java:61)

When i used gradle from cmd however it worked

projectfolder> set PATH=%PATH%;C:\AndroidStudio2.0\gradle\gradle-2.14.1\bin\
projectfolder> set GRADLE_HOME=C:\AndroidStudio2.0\gradle\gradle-2.14.1\bin\
projectfolder> cd C:\projectfolder\
projectfolder> gradle
BUILD SUCCESSFUL

In cmd i see that the gradle versions and android sdk version were correct

C:\>set | find "JAVA_HOME"
JAVA_HOME=C:\Java\jdk1.8.0_111\

However in C:\Users\.AndroidStudio2.2\system\log\idea.log it said something else:

2016-11-29 16:04:10,597 [ 107684]   INFO - s.plugins.gradle.GradleManager - Instructing gradle to use java from C:/AndroidStudio2.0/jre

After messing up Android Studio config files i ended up reinstalling everything in correct order (Java, Android Studio, Project) and it worked.

I got the same issue after updating my android studio to 1.5

Here is my error stack trace.

Error:A problem occurred configuring root project 'Kargo'.

java.io.FileNotFoundException: /home/adiyatmubarak/Documents/android-studio/gradle/gradle-2.4/lib/plugins/gradle-diagnostics-2.4.jar (No such file or directory)

After I checked to the android studio instalation directory within gradle, my gradle was gradle-2.8 I don't know how to setup my android studio path location, but for temporary fix I just rename it to gradle-2.4 and my problem solved.
