Eclipse Does Not Recognize JRE 8 as Greater Than JRE 5
提问by Dave C
I have installed Java 8 on my machine and have started a project with it. However, when I use an @Overrideannotation, the code is underlined in red, and the error Syntax error, annotations are only available if source level is 1.5 or greaterappears.
我已经在我的机器上安装了 Java 8 并用它启动了一个项目。但是，当我使用@Override注释时，代码以红色下划线，并Syntax error, annotations are only available if source level is 1.5 or greater出现错误。
I have installed the released Eclipse Java Development Tools Patch with Java 8 support (for Kepler SR2), but this only adds support for new features in Java 8, and does not fix the bug with annotations.
我已经安装了已发布的带有 Java 8 支持的 Eclipse Java 开发工具补丁（用于 Kepler SR2），但这仅增加了对 Java 8 中新功能的支持，并没有修复带有注释的错误。

Make sure your INSTALLED_JRE is pointing to jdk 1.8 in eclipse
确保您的 INSTALLED_JRE 在 Eclipse 中指向 jdk 1.8
Preference > java > installed_jre
Make sure java > compiler is set to 1.8 in eclipse
确保在 Eclipse 中将 java > compiler 设置为 1.8
preference > java > compiler > compiler compliance level

If you are using maven, you can try right click the project name and run Maven/Update Project.
如果您使用的是 maven，您可以尝试右键单击项目名称并运行 Maven/Update Project。

by default 1.4 version will set, so make sure set preference > java > compiler > compiler compliance level in eclipse IDE
默认情况下将设置 1.4 版本，因此请确保在 Eclipse IDE 中设置首选项 > java > 编译器 > 编译器合规性级别
