但是,下面是项目的构建路径详细信息有JRE - 8设置:
However, below is the build path details of the project which clearly has JRE - 8 set up:
和编译设置:
无论我构建项目多少次,我都会遇到同样的错误。即使在清理项目并从日食中刷新它也无济于事。请指导。
No matter how many times I build the project, i get the same error. Even after cleaning the project and refreshing it from eclipse doesn't help. Please guide.
更新:
添加属性以设置maven编译器插件
After adding the properties to set maven compiler plugin
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
,

这是代码片段,提供来自MainUITabbed类的编译错误:
And here is the code snippet giving the compilation error from MainUITabbed class:
import com.apple.eawt.Application;
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Application application = Application.getApplication(); // line 93
ImageIcon imgicon = new ImageIcon(getClass().getResource(
"ICON.jpg"));
Image img = imgicon.getImage();
application.setDockIconImage(img);
MainUITabbed frame = new MainUITabbed();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
推荐答案
将此添加到POM修复它为了我。请根据需要调整版本
Adding this to POM fixed it for me. Please adjust Version as you need
