java - 使用 Pixelmon mod 1.12.2-6.3.1 在 Eclipse 中运行 Minecraft Forge 服务器/客户端

Question

我能够按照他们指示的方式运行带有 Pixelmon mod 的服务器，即。使用锻造发射器。我想为 Pixelmon 编写一个 side mod，并尝试在 Eclipse 中运行 forge 服务器。服务器和客户端使用我自己的 mod 运行良好，或者除了使用 forge 打包的 mod 之外没有其他 mod，但是当我将 Pixelmon jar 放入 mods 文件夹时它崩溃了(请参见下面的跟踪)。

到目前为止我检查过的内容:

• forge 版本 2705 对于 Pixelmon 6.3.1 是正确的
• 使用 Java 8
• jar 文件上没有 .zip 扩展名
• 未提取 jar 文件
• 没有 OOM 问题
• Minecraft 1.12.2 适用于 Pixelmon 6.3.1

对于我可能做错了什么以及接下来可以尝试的任何想法？

(来自崩溃日志)

错误的详细演练、其代码路径和所有已知详细信息如下:

Answer 1

这是因为 mod jar 被混淆了

An aside about obfuscated names

Minecraft has 3 levels of naming:

1. Notch Names - these are the names of methods and fields that Minecraft uses when distributed. Often things like a.aa and b.cf2. This is the fully obfuscated state
2. SRG Names - these are the names given to methods and fields by the runtime deobfuscation process that Forge performs when you run the game. Compiled mods use these names, as they are consistent across minor versions
3. MCP Names - these are the human readable names you see inside Eclipse. These names are supplied by hand when someone figures out what a field or method does via the MCP Bot on IRC. Installing the Forge development environment with the MDK grabs the "current" mappings when you run gradlew setup

为了在开发环境中运行mod，您需要先对其进行反混淆，将SRG名称更改为MCP名称，以便它可以在开发环境中运行。

有几种方法可以做到这一点:

1. 从 mod 作者那里获取“源”jar(取决于作者的想法；可能是也可能不是公共(public)或开源的，有 API 等)
2. 使用Code Chicken Core在 Eclipse 中执行运行时 deobf(可能有效，也可能无效；注意:您需要源 jar)
3. 使用类似 BON2 的工具(没用过，应该可以)
4. 使用 Gradle 对 mod 进行反混淆(应该始终有效)

此处选项 4 的问题在于，虽然我知道这是可能的，但我无法(并且已经有一段时间无法)找到必要的说明。我现在能找到的东西，由知道如何做 4 的人发布，建议做 3。
