java Android：重建现在需要编译器合规性级别 5.0 或 6.0。而是找到了“1.7”。为什么要删除@Override？

After rebuilding my PC I get this error on importing my projects.

重建我的 PC 后，我在导入我的项目时遇到此错误。

Android requires compiler compliance level 5.0 or 6.0. Found '1.7' instead. Please use Android Tools > Fix Project Properties.

I have seen this raised on SO and I can fix my projects by doing the Fix Proj, and then removing all my @OVerrides.

我已经在 SO 上看到了这个问题，我可以通过执行 Fix Proj 来修复我的项目，然后删除我所有的 @Overrides。

this question is why do I now require to remove @Overrides? and will this alter my projects in anyway?

这个问题是为什么我现在需要删除@Overrides？这会改变我的项目吗？

干杯

Edit to add walkthrough information.

编辑以添加演练信息。

I import a project, I get the error shown above. I then do the Android Tools > Fix Project Properties. This now sets Project>Properties Java Compile to Compiler Compliance Level 1.5

我导入一个项目，出现上面显示的错误。然后我做Android Tools > Fix Project Properties. 这现在将 Project>Properties Java Compile 设置为 Compiler Compliance Level 1.5

After this I am left with a series of errors within my java files. on this particular project my errors are on

在此之后，我的 java 文件中出现了一系列错误。在这个特定的项目中，我的错误出现在

@Override 
public void run() {... 

Error marker to left of error read...

错误读取左侧的错误标记...

Multiple markers at this line
    - The method run() of type new Runnable(){} must override a superclass 
     method
    - implements java.lang.Runnable.run

the error hover in eclipse suggests I remove the @Override to fix this issue, and if I do remove the @Override it does fix the issue and my project now compiles and runs. Is this incorrect?

eclipse 中的错误悬停表明我删除了@Override 来解决这个问题，如果我删除了@Override，它确实解决了这个问题，我的项目现在可以编译并运行。这不正确吗？

p.s. I just wrote all that up, changed the Java Compliance level to 1.6 and all the override errors went away! Could someone explain (and I totally appreciate this might be totally off topic) why?

ps 我刚刚写了所有这些，将 Java 合规性级别更改为 1.6，所有覆盖错误都消失了！有人可以解释一下（我完全理解这可能完全偏离主题）为什么？

Dont remove any @overide notation.

不要删除任何@overide 符号。

you must set project compatibility to Java 5.0 or Java 6.0.

您必须将项目兼容性设置为 Java 5.0 或 Java 6.0。

To do that, 2 options:

为此，有 2 个选项：

1) right-click on your project and select "Android Tools -> Fix Project Properties"(if this din't work, try second option)

1）右键单击您的项目并选择"Android Tools -> Fix Project Properties"（如果这不起作用，请尝试第二个选项）

2) right-click on your project and select "Properties -> Java Compiler", check "Enable project specific settings"and select 1.5 or 1.6 from "Compiler compliance settings"select box.

2) 右键单击​​您的项目并选择"Properties -> Java Compiler"，选中“启用项目特定设置”并从“编译器合规性设置”选择框中选择 1.5 或 1.6 。
