从jar文件还原项目 [英] restore project from jar file

问题描述

首先，我想指出的是，对于netbeans和java来说，它是相当新的东西，无法在网络上准确找到我需要的东西. 我下载了软件的源文件，并在netbeans上对其进行了修改.自然，在构建项目时，netbeans会在(例如)documents/project_folder/dist/lib文件夹以及我可以使用的完成的JAR文件中创建. 如果我错误地删除了源文件，并且想使用以前仍然使用的JAR和lib文件夹将我以前对新的源文件所做的所有更改都应用到该文件中，这可能吗?怎么办?

first i'd like to point out that im fairly new to netbeans and java, couldnt exactly find what i need on the web.
I downloaded a software's source files and was modifying it on netbeans. naturally when building the project, netbeans creates in (for example) documents/project_folder/dist/ a lib folder and the finished JAR file that i can use.
if i delete by mistake the source files, and would like to apply all the changes i previously made to fresh source files using the JAR and lib folder i still have, is it possible and how?

推荐答案

首先，不可能再次从lib文件夹中的jar文件中获取源. Jar文件是可执行文件，将仅包含类文件.您可以使用Java反编译器再次获取源代码.

First of all it is not possible to get a source again from jar file in lib folder. Jar file is executable file which will just contain class files. You can use java decompilers to get source again.
