Java 如何在 Eclipse 中更改包名称？

How to change a package name in Eclipse?

提问by AndreaNobili

In Eclipse I have a simple Java project that contains a package named (default package)and inside this package I have a class.

在 Eclipse 中，我有一个简单的 Java 项目，其中包含一个名为（默认包）的包，在这个包中我有一个类。

I want to rename this package into something like: com.myCompany.executable

我想将此包重命名为：com.myCompany.executable

I tried to select the (default package) ---> right click ---> refactorbut now I see only the single voice named: Infer generic type argumentsbut not the possibility to change the package name.

我试图选择（默认包）---> 右键单击​​ ---> 重构，但现在我只看到名为：推断泛型类型参数的单个声音，但不能更改包名称。

Why? What have I to do in Eclipse to change the name of the package?

You can't rename default package since it actually doesn't even exist. All files in default package are actually in srcfolder.

您无法重命名默认包，因为它实际上甚至不存在。默认包中的所有文件实际上都在src文件夹中。

src--
    |
    MyClass1.java <==== These files are in default package
    MyClass2.java
    |
    org
      |
      mypackage
              |
              MyClass3.java <=== class in org.mypackage package

Just create new package and move your classes within.

只需创建新包并在其中移动您的类。
