resValue gradle error: Unsupported type "String" in "generated.xml"

Question

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.

The problem I have described in detail:

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 

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\...\build\res\generated\release\values\generated.xml 

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

• over IDE:
  • rebuild project
  • execute external task "assembleBuildVariant"
• over command line:
  • gradlew assembleBuildVariant

Strange gradle console output:

:app:generateBuildVariantResValues UP-TO-DATE 

My 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"     } } 

My "generated.xml":

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

My question:

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

My build.gradle (UPDATE 2014-02-10 based on rciovatis answer):

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"     } } 

UPDATE 2014-02-14 IT WORKS:

After an update of the gradle android plugin everything works fine:

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

• all
• generated (-> here you find the generated resource values by resValue)

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> 

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

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

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"         }     } } 

Please note that:

• item type must be string and not String
• item name must not contain spaces (as normal resource name)

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