How can I extract .class files from .jar files?
问题 A quick question: I like the look of this bit of Ant: <fileset dir="${lib}"> <patternset refid="myPattern" /> </fileset> So I could use this e.g. to copy a few .jar files from ${lib} that match myPattern. What if what I really want is to look into each .jar in ${lib} and select only .class files that match myPattern? 回答1: The unjar task does pretty much what you want here out of the box. Use a fileset to specify the jar files you want to extract from, and a patternset to specify which files
