vm 虚拟机执行 ./script/create-dist.sh 找不到java类 about ratel-core HOT 4 CLOSED

完全看不懂描述的啥东西

from ratel-core.

就是显示BUILD SUCCESSFUL in 1m 52s，过后说找不到java类：

额。。。这是警告，涉及到java和android平台的一些细小差异。
比如java.util.function.Function是jdk8才会有的东西，有些库里面使用了jdk8的这些东西，但是我们实际上希望我们的工具可以在jdk7上面运行（没记错的话，对标到Android大概是Android7对应jdk7）。

故这是一个java语法脱糖的过程，这个过程所有java8语法降级到java7上面都可以。这个知识你要是开发过Android自然就应该懂得。 https://www.freesion.com/article/33001424487/

总结起来，这个告警是几乎所有的Android代码在编译过程都会发生的（希望app运行在Android7以及一下的设备上，但是代码以来的api在java8上面构建）。忽略即可。至于为啥会报警，为啥这个报警对我们的程序没有影响，篇幅有限，不太方便展开，你自己研究吧。

issues我关闭了，下次提问题好好做一下排版，清楚的描述你的问题。否则不回答直接close

好的！感谢大哥的解答！下次会注意。
