从我收集到的信息来看，使用jre1.8.0安装JDK 10.0.2和eclipse似乎是一个问题，但我不确定，也不确定如何解决此问题。

Answer 1

这里的根本问题是Java9 +的ByteBuffer#flip()可以返回ByteBuffer。代码似乎依赖于获取这种类型。

在这种情况下，因为在Buffer类中定义了flip方法，Java 8（及更早版本）返回了Buffer。

Buffer flippedBuffer = byteBuffer.flip(); // also works in Java9+
ByteBuffer flippedByteBuffer = byteBuffer.flip(); // Java 9+ only

Minecraft客户端无法从Eclipse中运行
