IntelliJ不会在List/Map的末尾接受Java8和钻石-IntelliJwon'tacceptJava8anddiamondsattheendofList/Map

Try to run the project, if this is your error message:

尝试运行该项目,如果这是您的错误消息:

Then I suggest you have a little look into your pom-file.

然后我建议你稍微查看你的pom文件。

This project was built using the intelliJ maven project setting, and it was missing this lovely line of code:

这个项目是使用intelliJ maven项目设置构建的,它缺少这段可爱的代码:

    
        
            org.apache.maven.plugins
            maven-compiler-plugin
            
                1.8
                1.8
            
        
    

IntelliJ doesn't (at least in my case) generate the version in the pom (despite that I picked all the settings for it).

IntelliJ没有(至少在我的情况下)在pom中生成版本(尽管我选择了它的所有设置)。

I tried specifying the compiler version in the plugin too, to no avail. Have you tried invalidating the cache? It's File -> Invalidate Caches/Restart.... I would probably restart as well for good measure.

我也尝试在插件中指定编译器版本,但无济于事。您是否尝试过无效缓存?这是文件 - >无效缓存/重新启动....我可能会重新启动以获得良好的衡量标准。
