"proguardInJars"的语义是什么?在SBT Android-Plugin中? [英] What are the semantics of "proguardInJars" in SBT Android-Plugin?

问题描述

在SBT Android插件的proguardTask中，有一个值proguardInJars.
在我的简单测试项目中，它包含C:\Users\Administrator\.sbt\boot\scala-2.9.1\lib\scala-library.jar.

In SBT Android Plugin, in proguardTask, there is a value proguardInJars.
In my simple test project it contains C:\Users\Administrator\.sbt\boot\scala-2.9.1\lib\scala-library.jar.

然后将其与我自己的已编译类组合成另一个值inJars.

It is then combined with my own compiled classes into another value inJars.

但是，通过在其后面附加一些内容来进行组合.这是来自jberkel/android-plugin的代码，用于执行此操作:

However, it is combined by appending something to it. Here's the code from jberkel/android-plugin that does that:

val manifestr = List("!META-INF/MANIFEST.MF", "R.class", "R$*.class", "TR.class", "TR$.class", "library.properties")
val sep = JFile.pathSeparator
val inJars = ("\"" + classDirectory.absolutePath + "\"") +: proguardInJars.map("\"" + _ + "\""+manifestr.mkString("(", ",!**/", ")"))

我想知道是否有人知道所添加内容的语义.
另外，如果我要将inJars分解为单独的值，我是否仍需要将该清单内容附加到proguardInJars以便proguardTask正常运行?

I am wondering is anyone knows the semantics of that added stuff.
Also, if I were to break inJars into separate values, would I still need to append that manifest stuff to proguardInJars in order for proguardTask to run without problems?

推荐答案

此时android插件正在为ProGuard准备injars命令行参数. ProGuard使用通用的类路径来确定要考虑的jar文件中的哪些文件，而不考虑这些jar文件中文件匹配器的形式.

The android plugin is preparing the injars command line argument for ProGuard at that point. ProGuard uses generalized classpaths to figure out which files from a jar to consider, and which not to, a form of file matchers within the jars.

例如，.../scala-library.jar(!META-INF/MANIFEST.MF,!**/R.class,!**/R$*.class,!**/TR.class,!**/TR$.class,!**/library.properties)表示不应将文件R/TR.class或以R$/TR$开头的类文件(!)作为输入考虑.

For example, .../scala-library.jar(!META-INF/MANIFEST.MF,!**/R.class,!**/R$*.class,!**/TR.class,!**/TR$.class,!**/library.properties) means that files R/TR.class or classfiles starting with R$/TR$ should not (!) be taken into consideration as an input.
