反编译Java项目并编译 [英] Decompile a Java project and compile
问题描述
我正在尝试反编译一个java项目（.jar）文件，我可以从中获取.java文件。现在我该如何编译回来？我能够将.java文件添加到Netbeans中，就像单个文件一样。但是如何将它添加为项目添加编译呢？该项目是一个JavaFX项目。所以请帮助我。
I am trying to decompile a java project(.jar) file and I am able to get .java files from it. Now how can I compile it back? I am able to add the .java files to Netbeans just as a single file.But how can I add it as a project add compile it? The project is a JavaFX project. So please help me on this.
推荐答案
有很多方法可以实现这一目标，但我认为你不会将jar中的项目导入开箱即用（在这种情况下，这是一种非常有用的）。
There are many ways to achieve this, but I don't think you will be able to import the project inside the jar just out of the box ( in this case, out-of-the-jar ) like that.
我们可以使用最基本的技术（我承认有点脏）但是它有效。
We can use the most basic technique ( a bit dirty I admit ) but it works.
- 在目录中提取jar的内容并像之前那样对其进行反编译
- 接下来，在netbeans中创建一个空项目（没有src目录或任何内容）
- 将反编译项目的内容复制到此netbeans文件夹中。您现在应该看到一些文件的骨架结构。 注意 poject是inisde netbeans但它还不是一个java项目。
- 编辑netbeans项目的类路径并添加java库以使其成为Java netbeans项目。
- Extract the contents of the jar in a directory and decompile it like you done it before
- Next, make an empty project inside netbeans ( with no src directory or anything )
- Copy the contents of your decompiled project into this netbeans folder. You should now see a skeleton structure of some files. Note The poject is inisde netbeans but it is not a java project yet.
- Edit the classpath of the netbeans project and add java library to make it into a Java netbeans project.
我有时使用的另一种技术是我制作IDE所需的所有项目文件（在我的案例中是Eclipse） ）手动然后告诉eclipse导入项目。当eclipse找到所有必需的文件（.project，.classpath和all）时，它会很好地导入IDE中
The other technique that I use sometimes is that I make all the project files required by the IDE (Eclipse in my case) manually and then tell eclipse to import the project. When eclipse finds all the required files ( .project, .classpath and all ), it imports into the IDE just fine
