我将缩小选项添加到 gradle ,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 cofig :
debug{
project.archivesBaseName = "zcctest131"
signingConfig signingConfigs.myConfig
minifyEnabled true
shrinkResources true
}
我还启用了multidex选项:
multiDexEnabled = true
编译'com.android.support:multidex:1.0.1'
通过检查生成的component.flags文件,其路径为app/build/intermediates/multi-dex/defaultConfig/debug/components.jar
,我发现第一行变为:
outjars /Users/zcc/app/build/intermediates/multi-dex/defaultConfig/debug/componentClasses.jar
:
injars /Users/zcc/app/build/intermediates/multi-dex/anZhi/release/allclasses.jar
缺少导致IOException
的。
proguard源代码如下供您参考:
/**
* 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。
答案 0 :(得分:0)
嗯,正确的方法是在构建类型中添加proguard规则文件,而不是在Flavors块中。然后问题就解决了。
