JRE仿真库中不存在方法“ Iterable.forEach（Consumer <！-？super T->）”

Question

我正在将IntelliJ用于我的GWT项目和此代码

LinkedList<String> modelValue = new LinkedList<>();
componentValue.forEach(product -> {
    Product p = (Product) product;
    modelValue.add(p.getObjectId());
});

我收到此错误：

Method 'Iterable.forEach(Consumer<? super T>)' is not present in JRE Emulation Library so it cannot be used in client code of 'com.mycompany.app.AppTest' GWT module less... (Ctrl+F1) 
This inspection reports usages in client code of JDK classes which are not present in the JRE Emulation Library.

如何使用IntelliJ修复此问题？

Answer 1

您需要使用GWT 2.8版才能在Java 8中使用新的API，例如Iterable.forEach()。
