Java / Maven硒-Java 7的Retrolambdas

问题描述

大家好：我在Java 7中使用Lambda时遇到了一些问题。出于工作目的，我无法升级到Java8。我正在研究Retrolambdas，并尝试实现它们。

这是我的POM

如您所见，我为Retrolambdas添加了Plugin和依赖项，但是在某些类中，无法识别某些导入和方法，例如next：

import java.util.stream.Stream;

import static java.lang.Math.toIntExact;

这里的部分课程：

public Object[][] getData(Class clazz) {
        ClassLoader classLoader = getClass().getClassLoader();
        Path path = null;
        try {
            String name = clazz.getSimpleName() + ".txt";
            path = Paths.get(classLoader.getResource("datos/" + name).toURI());
        } catch (NullPointerException | URISyntaxException e) {
            logger.error(e);
        }
        try {
            Stream<String> stream = Files.lines(path);
            List<String> stream2 = new ArrayList<>();
            stream.forEach((String s) -> stream2.add(s));
            int count = toIntExact(stream2.size());
            stream2.forEach(s -> initializeArray(count, fieldCount(s)));
            x = 0;
            stream2.forEach(s -> assign(field(s)));
        } catch (IOException e) {
            logger.error(e);
        }
        return result;
    }

一些注释，如forEach，toIntExact，Stream，行用红色标记。

有人可以帮我吗？
