Android Stutio 3.0 - Gradle sync failed

 0.Android Studio 權威教程

(url:http://blog.csdn.net/column/details/zsl-androidstudio.html) 

 

1. 項目老是報錯:

Gradle sync failed: Argument for @NotNull parameter 'key' of com/android/tools/idea/gradle/project/model/ide/android/ModelCache.computeIfAbsent must not be null
Gradle project sync failed. pliease fix your project and try again

solution, Gradle 設置其到本地(我android-studio安裝在"C:/android-studio"):
File->Setting->Build,Execution,Deployment->Gradle:
1. Use locla gradle distribution
C:/android-studio/gradle/gradle-4.1-milestone-1

 不行的話, 見 第4點 , 此處設置 恢復默認, 更改 Gradle 版本

 

2.修改LogCat的顏色

1. File->Settings 或Ctrl + Alt +S
2. 找到 Editor -> Colors &Fonts -> Android Logcat 或在上面的搜索框中輸入Logcat
3. 點中Verbose , Info, Debug等選項，然后在后面將Use Inberited attributes 去掉勾選
4. 再將 Foreground 前的復選框選上，就可以雙擊后面的框框去選擇顏色了
5. Apply–>OK

Log級別    色值
VERBOSE   BBBBBB
DEBUG     63AABB
INFO      211DD5
WARN      BBBB23
ERROR     FF0006
ASSERT    8F0005

3.添加你見過的最牛Log*神器*

logcat中打印位置,可以點擊跳轉 Git:https://github.com/orhanobut/logger

4.AndroidStudio中使用Aliyun Maven

Aliyun Maven地址：http://maven.aliyun.com

在項目級別的build.gradle中添加如下Maven地址：

buildscript {
    repositories {
        maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
    }
}

allprojects {
    repositories {
        maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        jcenter()
    }
}

 

 

4.Error:Unable to find method 'com.android.build.gradle.tasks.factory.AndroidJavaCompile.setDependencyCacheDir(Ljava/io/File;)V'.

Error:Unable to find method 'com.android.build.gradle.tasks.factory.AndroidJavaCompile.setDependencyCacheDir(Ljava/io/File;)V'. Possible causes for this unexpected error include:

• Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) Re-download dependencies and sync project (requires network)
• The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem. Stop Gradle build processes (requires restart)
• Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.

In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

按錯誤提示，多次點擊【Re-download dependencies and sync project (requires network)】發覺都無任何效果；點擊【Stop Gradle build processes (requires restart)】，在Android Studio重啟幾次之后也無效果。 
此時懷疑有可能是Gradle版本問題，查看該程序的Gradle版本為：

classpath 'com.android.tools.build:gradle:2.1.3'

查看本機發現並不包含此版本的Gradle，因此將其修改為本機已經下載的Gradle版本：

classpath 'com.android.tools.build:gradle:2.2.0'

重新編譯，錯誤變成了： 
 
該問題應該是因為本機沒有安裝appcompat-v7:25.3.1版本造成的，可采用如下兩種解決方案： 
①按照提示安裝新版本的包； 
②將該版本修改為本機已安裝的包版本，如25.2.0； 
經修改過后，程序可以編譯通過，問題順利解決。

上面問號中間是 網上搜到比較近似的,  我的實際情況是:

項目的  build.gradle 配置

buildscript {
    repositories {
        maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    }
}

allprojects {
    repositories {
        maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

 

Gradle 配置為 2.2.0

加 buildscript 和 allprojects 的 maven 配置是為了 下載資源 使用國內的  maven  鏡像, 速度快

 之后更改 gradle/wrapper/gradle-wrapper.properties    (不手動改,也應該有錯誤提示, 點擊自動 Fix )

    distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip

 然后編譯通過!!
