Netty 无法使用 Java 17 模块化 JDK

Question

使用 JDK 17 的 Netty 拆分包问题。它是非模块化 jar，我试图将其包含在我的模块化项目中。我添加了一个 module-info.java 然后包含在下面的要求

module mycustommodule {
    requires io.netty.buffer;
    requires io.netty.transport;
}

这是因为 io.netty jar 不是模块。如果您使用 7-zip 之类的东西窥视它们，您将看不到 module-info.class 文件。然而，“需求”期望这些是模块。
