java - Minecraft 客户端无法从 Eclipse 运行

Question

我开始尝试修改 Minecraft 1.7.10，但是每当我尝试从 eclipse 运行我的测试 mod 时，客户端就会崩溃(问题不在 mod 中，因为我构建了它并将其加载到 Minecraft 中并且它工作了。)这是崩溃日志:

根据我收集的信息，我使用 jre1.8.0 安装 JDK 10.0.2 和 eclipse 似乎有问题，但我不确定，也不知道如何解决这个问题。

Answer 1

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

在这种情况下，Java 8(及更早版本)返回一个 Buffer，因为 flip 方法是在 Buffer 类中定义的。

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