我加入了收縮選項，以我的gradle ，而下面的錯誤總是會發生：安卓gradle這個shrinkresources沒有injars在components.flags gennerated文件
: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.
，這裏是我的gradle cofig：
debug{
project.archivesBaseName = "zcctest131"
signingConfig signingConfigs.myConfig
minifyEnabled true
shrinkResources true
}
，我也啓用了multidex選項：
multiDexEnabled = true
編譯'com.android.support:multidex:1.0.1'
通過檢查產生component.flags文件，其路徑爲app/build/intermediates/multi-dex/defaultConfig/debug/components.jar，我發現成爲第一行：
outjars /Users/zcc/app/build/intermediates/multi-dex/defaultConfig/debug/componentClasses.jar
的：
injars /Users/zcc/app/build/intermediates/multi-dex/anZhi/release/allclasses.jar
缺失導致IOException。
ProGuard的源代碼，供大家參考如下：
/**
* 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));

我怎樣才能解決這個問題？ 非常感謝。
