Android gradle shrinkresources没有在组件中生成injars.标记文件

Question

我给我的gradle添加了收缩选项，然而以下错误总是发生:

:app:shrinkDefaultConfigDebugMultiDexComponents FAILED
Error:Execution failed for task    
:app:shrinkDefaultConfigDebugMultiDexComponents'.
java.io.IOException: The output jar [[mypath]/componentClasses.jar] must be specified after an input jar, or it will be empty.

这是我的gradle config:

debug{
        project.archivesBaseName = "zcctest131"
        signingConfig signingConfigs.myConfig
        minifyEnabled true
        shrinkResources true
 }

和我还启用了多重索引选项:

 multiDexEnabled = true

编译'com.android.support:multidex:1.0.1'

通过检查生成的组件。flags文件，其路径为app/build/intermediates/multi-dex/defaultConfig/debug/components.jar，我发现第一行变成:

outjars /Users/zcc/app/build/intermediates/multi-dex/defaultConfig/debug/componentClasses.jar

:

injars /Users/zcc/app/build/intermediates/multi-dex/anZhi/release/allclasses.jar

缺失，导致IOException。

proguard源代码如下:

 /**
 * Reads the input jars (or directories).
 */
private void readInput() throws IOException
{
    if (configuration.verbose)
    {
        System.out.println("Reading jars...");
    }
    // Check if we have at least some program jars.
    if (configuration.programJars == null)
    {
        throw new IOException("The input is empty. You have to specify one or more '-injars' options.");
    }
    // Read the input program jars.
    readInput("Reading program ",
              configuration.programJars,
              createDataEntryClassPoolFiller(false));

我该如何解决这个问题?非常感谢。

正确的方法是将proguard规则文件添加到构建类型中，而不是添加到Flavors块中。
