resValue gradle 错误:不支持的类型“字符串"在“生成的.xml"中

问题描述

几周前我发布了一个问题如何根据 buildType 覆盖资源.就在昨天，还有一个 gradle 插件版本为 android.根据这篇关于 G+ 的帖子，我决定写下这个问题.

A few weeks ago I posted a question How to override resources depending on buildType. And just yesterday there was a gradle plugin release for android. Based on this post on G+ I decided to write this question.

我已经详细描述的问题:

我想根据 buildType 创建一些资源值，但这不能正常工作:只有在我通过命令行进行完整构建时才会创建文件generated.xml":

I want to create some resource values depending on the buildType, but this doesn't work properly: The file "generated.xml" will be only created if I make a complete build over the command line:

gradlew build

但是通过命令行构建完整的项目我也得到了一个错误:

But I also get an error by building the complete project over comannd line:

* What went wrong: Execution failed for task ':app:merge<buildVariant>Resources'.
Unsupported type 'String' in file C:Users...uild
esgenerated
eleasevaluesgenerated.xml

所有其他构建试用版都不会创建此文件.我尝试了以下操作:

Every other build-trial doesn't create this file. I tried following:

• 通过 IDE:
  • 重建项目
  • 执行外部任务assembleBuildVariant"
  • gradlew assembleBuildVariant

  奇怪的 gradle 控制台输出:

  Strange gradle console output:

  :app:generateBuildVariantResValues UP-TO-DATE
  

  我的 build.gradle:

  buildTypes {
      debug{
          buildConfigField "String", "FOO", ""FOO DEBUG""
          resValue "String", "RES FOO", "RES FOO DEBUG"
      }
      release {
          buildConfigField "String", "FOO", ""FOO RELEASE""
          resValue "String", "RES FOO", "RES FOO RELEASE"
      }
  }
  

  我的生成的.xml":

  <!-- Automatically generated file. DO NOT MODIFY -->
  
  <!-- Values from build type: release -->
  <item name="RES FOO" type="String">RES FOO RELEASE</item>
  

  我的问题:

  这是一个错误还是我错过了什么?为什么这个文件不是由 IDE 上的 Rebuild 创建的?

  Is this a bug or did I miss something? And why this file isn't created by a Rebuild over the IDE?

  我的 build.gradle(更新 2014-02-10 基于 rciovatis 答案):

  defaultConfig {
      minSdkVersion 14
      targetSdkVersion 19
      versionCode 1
      versionName "1.0"
      resValue "string", "RES_FOO", "RES FOO"
  }
  
  buildTypes {
      debug{
          buildConfigField "String", "FOO", ""FOO DEBUG""
          resValue "string", "RES_FOO", "RES FOO DEBUG"
      }
      release {
          buildConfigField "String", "FOO", ""FOO RELEASE""
          resValue "string", "RES_FOO", "RES FOO RELEASE"
      }
  }
  

  2014 年 2 月 14 日更新它的工作原理:

  更新 gradle android 插件之后一切正常:

  在/build/res/all/中，您应该会看到以下文件夹:

  In /build/res/all/ you should see following folders:

  • 全部
  • 已生成(-> 在这里您可以通过 resValue 找到生成的资源值)
  • all
  • generated (-> here you find the generated resource values by resValue)

  第一个文件夹all 包含所有合并的资源.在方向 all/<buildVariant>/values/values.xml 你应该找到生成的资源，在我的例子中:

  The first folder all contains all merged resources. In the direction all/<buildVariant>/values/values.xml you should find the generated resources, in my case:

  // for buildType DEBUG
  <item name="TESTFOO" type="string">TEST FOO DEBUG</item>
  // for buildType RELEASE
  <item name="TESTFOO" type="string">TEST FOO RELEASE</item>
  

  要获取代码中的值，只需像其他所有资源一样使用生成的资源:

  To get the values in code just use the generated resource like all others:

  getResources().getString(R.string.TESTFOO)
  

  推荐答案

  我解决了在 defaultConfig 块中添加资源的问题.对你来说，它会是这样的:

  I solved adding the resources also in the defaultConfig block. For you it would be something like:

  android {
      defaultConfig {
          resValue "string", "RES_FOO", "RES FOO RELEASE"
      }
  
      buildTypes {
          debug{
              buildConfigField "String", "FOO", ""FOO DEBUG""
              resValue "string", "RES_FOO", "RES FOO DEBUG"
          }
          release {
              buildConfigField "String", "FOO", ""FOO RELEASE""
              resValue "string", "RES_FOO", "RES FOO RELEASE"
          }
      }
  }
  

  请注意:

  • 项目类型必须是 string 而不是 String
  • 项目名称不得包含空格(与正常资源名称一样)

  从 0.8.3 开始，只需在构建类型块中声明 resValue 即可正常工作.

  Since 0.8.3 it should works fine just declaring the resValue in the build type block.
