You need to disable that option in your 'save actions'.
您需要在“保存操作”中禁用该选项。
right click your project > properties, then go to java editor > save actions. go to 'configure', 'code style' tab, and you have it on the bottom ('private fields').
右键单击您的项目 > 属性，然后转到 Java 编辑器 > 保存操作。转到“配置”、“代码样式”选项卡，然后将其放在底部（“私有字段”）。

Window - Preferences - Java - Editor - Save Actions - Configure... - Code Style - Use modifier final when possible
窗口 - 首选项 - Java - 编辑器 - 保存操作 - 配置... - 代码样式 - 尽可能使用修饰符 final
The same option can be found in Java - Code Style - Clean up.
可以在 Java - Code Style - Clean up 中找到相同的选项。

If you want to leave this feature enabled in general but turn it off for a specific field, I found a simple workaround. Just declare a protected method that assigns to this field.
如果您想在一般情况下启用此功能但针对特定字段将其关闭，我找到了一个简单的解决方法。只需声明一个分配给该字段的受保护方法。
protected void preventFinal() {
field = null;
}
protected void preventFinal() {
field = null;
}

You can go to Project --> Properties --> Java Editor --> Save actions , Uncheck "Enable project specific settings"
您可以转到 Project --> Properties --> Java Editor --> Save actions ，取消选中“Enable project specific settings”

There is Section called Save Actions in Eclipse Window -> Preferences -> Java -> Editor. There You can Configure Aditional actions - > (tab) code style - > Variable declarations -> edit use of final keyword.
在 Eclipse Window -> Preferences -> Java -> Editor 中有一个名为 Save Actions 的部分。在那里您可以配置附加操作->（选项卡）代码样式-> 变量声明-> 编辑最终关键字的使用。
