列出javac编译的Java源文件
列出javac编译的Java源文件
提问于 2018-05-31 08:02:28
我有一系列小的Java项目( *.java文件中的类)，它们通过CLASSPATH引用大型代码库。代码存储库包括大量的*.java文件(源文件)和一些*.jar文件。我想将任何给定的项目从它的目录中分离出来，以便打包并分发它。
给定一个包含main方法的Java类作为给定项目的起点，如何列出用于编译给定Java类的所有文件，比如CLASSPATH上的*.java文件或*.jar文件？javac能否在编译过程中生成足够详细的日志？您是否可以单独使用Java API并以编程方式检查用于编译的源文件？

在编译过程中，javac能生成足够详细的日志吗？
javac有-verbose选项，它可以告诉您哪些JAR在类路径上，哪些JAR文件被编译。
javac -verbose <filepath>示例输出(编译使用Dummy2.java和一些JDK类的Dummy.java )：
