BuildConfig沒有得到正確創建（搖籃安卓）

Question

我想我們的Android應用程序轉換爲一個構建的gradle。我有這個項目，它的圖書館建設成功。我現在正在嘗試爲我們的各種環境創建單獨的應用程序（dev/test/prod擁有不同的URL，以供他們使用的寧靜服務）。

在周圍尋找，我覺得這樣做是讓不同BuildConfig爲每個環境的最佳途徑。這是我的嘗試：

import java.util.regex.Pattern 

buildscript { 
    repositories { 
     mavenCentral() 
    } 

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

apply plugin: 'android' 

task('increaseVersionCode') << { 
    def manifestFile = file("AndroidManifest.xml") 
    def pattern = Pattern.compile("versionCode=\"(\\d+)\"") 
    def manifestText = manifestFile.getText() 
    def matcher = pattern.matcher(manifestText) 
    matcher.find() 
    def versionCode = Integer.parseInt(matcher.group(1)) 
    def manifestContent = matcher.replaceAll("versionCode=\"" + ++versionCode + "\"") 
    manifestFile.write(manifestContent) 
} 

tasks.whenTaskAdded { task -> 
    if (task.name == 'generateReleaseBuildConfig') { 
     task.dependsOn 'increaseVersionCode' 
    } 
} 

dependencies { 
    compile 'com.android.support:support-v4:19.0.0' 
    compile files('libs/commons-io-2.4.jar', 
        'libs/google-play-services.jar', 
        'libs/gson-2.2.4.jar', 
        'libs/universal-image-loader-1.8.6.jar', 
        'libs/wakeful-1.0.1.jar') 
    compile project(':pulltorefresh_lib') 
    compile project(':edgeeffect_lib') 
    compile project(':viewpagerindicator_lib')   
} 

android { 
    buildToolsVersion "18.1.1" 
    compileSdkVersion "Google Inc.:Google APIs:18" 

    defaultConfig { 
     minSdkVersion 14 
     targetSdkVersion 18 
    } 

    buildTypes { 
     debug { 
      packageNameSuffix ".debug" 
     } 
     dev.initWith(buildTypes.debug) 
     dev { 
      buildConfigField "String", "URL_SEARCH", "\"https://dev-search.example.com\";" 
      buildConfigField "String", "URL_CONNECT", "\"https://dev-connect.example.com\";" 
      buildConfigField "String", "URL_SVC_NEWSLIST", "\"https://dev-mobilenews.example.com/newslist\";" 
      buildConfigField "String", "URL_SVC_NEWSDETAIL", "\"https://dev-mobilenews.example.com/newsdetail\";" 
      buildConfigField "String", "URL_SVC_REGISTERENDPOINTS", "\"https://dev-mobilenews.example.com/registerendpoints\";" 
     } 
     prod.initWith(buildTypes.release) 
     prod { 
      buildConfigField "String", "URL_SEARCH", "\"https://search.example.com\";" 
      buildConfigField "String", "URL_CONNECT", "\"https://connect.example.com\";" 
      buildConfigField "String", "URL_SVC_NEWSLIST", "\"https://mobilenews.example.com/newslist\";" 
      buildConfigField "String", "URL_SVC_NEWSDETAIL", "\"https://mobilenews.example.com/newsdetail\";" 
      buildConfigField "String", "URL_SVC_REGISTERENDPOINTS", "\"https://mobilenews.pdc-np-cf.lmig.com/registerendpoints\";"   
     } 
    } 

    sourceSets { 
     main { 
      manifest.srcFile 'AndroidManifest.xml' 
      java.srcDirs = ['src'] 
      resources.srcDirs = ['src'] 
      res.srcDirs = ['res'] 
      assets.srcDirs = ['assets'] 
     } 
    } 
} 

的問題是，我BuildConfig.java似乎並沒有得到靜態變量注入，因此我得到類似的錯誤：

/Users/path/to/project/MainActivity.java:348: error: cannot find symbol 
      startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(BuildConfig.URL_SEARCH))); 
                      ^
    symbol: variable URL_SEARCH 
    location: class BuildConfig 
/Users/path/to/project/MainActivity.java:359: error: cannot find symbol 
      startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(BuildConfig.URL_CONNECT))); 
                      ^
    symbol: variable URL_CONNECT 
    location: class BuildConfig 
/Users/path/to/project/MainActivity.java:600: error: cannot find symbol 
      HttpPost httpPost = new HttpPost(BuildConfig.URL_SVC_REGISTERENDPOINTS); 
                 ^
    symbol: variable URL_SVC_REGISTERENDPOINTS 
    location: class BuildConfig 
/Users/path/to/project/service/AlarmNotificationService.java:145: error: cannot find symbol 
     String requestUrl = BuildConfig.URL_SVC_NEWSLIST + "?" 
            ^
    symbol: variable URL_SVC_NEWSLIST 
    location: class BuildConfig 
/Users/path/to/project/service/NewsService.java:240: error: cannot find symbol 
     String requestUrl = BuildConfig.URL_SVC_NEWSLIST + "?" 
            ^
    symbol: variable URL_SVC_NEWSLIST 
    location: class BuildConfig 
/Users/path/to/project/service/NewsService.java:530: error: cannot find symbol 
      HttpPost httpPost = new HttpPost(BuildConfig.URL_SVC_NEWSDETAIL); 
                 ^
    symbol: variable URL_SVC_NEWSDETAIL 
    location: class BuildConfig 
6 errors 

我構建/源/buildConfig/debug/com/.../BuildConfig.java文件包含：

/** 
* Automatically generated file. DO NOT MODIFY 
*/ 
package com....; 

public final class BuildConfig { 
    public static final boolean DEBUG = Boolean.parseBoolean("true"); 
    public static final String PACKAGE_NAME = "com.....debug"; 
    public static final String BUILD_TYPE = "debug"; 
    public static final String FLAVOR = ""; 
    public static final int VERSION_CODE = 5; 
} 

我在做什麼錯？

Answer 1

請確保您正在建設「開發」或「刺」變種。默認的「debug」和「release」變體中沒有BuildConfig定義。在Android Studio中，您可以在左下角選擇當前變種：

爲了簡化您的build.gradle文件，您可以定義：

buildTypes { 
    debug { 
     buildConfigField "String", "URL_SEARCH", "\"https://dev-search.example.com\"" 
     // etc. 
    } 
    release { 
     buildConfigField "String", "URL_SEARCH", "\"https://search.example.com\"" 
     // etc.  
    } 
} 

，然後只用默認的「調試」和「發佈」變體。從buildConfigField參數的值;：

最後，刪除分號（ '' 符號）。

Answer 2

我必須建立使用.initWith（someotherbuildtype）的類型是建立相關類似的問題，BuildConfig沒有被正確創建。我不得不切換到父構建變體並首先構建它，然後使用父構建好的構建類型。

Answer 3

以防萬一，幫助別人，在我的情況，這是一個缺少導入： import uk.co.yourpackage.yourapp.BuildConfig;

不知何故，無處在doc沒有提到你需要的是包括！讓我覺得它以某種方式自動導入，但它不是。至少不是對我來說......這麼多時間輸了......希望能幫助像我這樣的新手！

Answer 4

我有同樣的問題，並修復它象下面這樣：

buildConfigField 'String', 'BASE_URL', '"https://api.example.com"'
