反编译 MCP 错误(9.18 版)返回“反编译失败" [英] Decompiling MCP error (version 9.18) returns 'Decompile Failed'

问题描述

我决定采用 MCP 并下载它，但是，在运行 decompile.bat 时，它返回一个错误.

I have decided to take on MCP and have downloaded it, however, when running the decompile.bat, it returns an error.

(我运行的是 32 位 Windows 10)

(I'm running 32-bit Windows 10)

这是它返回的内容:

推荐答案

这是反编译系统内存不足造成的.我不完全确定为什么会发生这种情况，但它也发生在我身上.

This is caused by the decompilation system running out of RAM. I'm not entirely sure why it's happening, but it also was happening to me.

如果您使用的是 Minecraft Forge 的 ForgeGradle，请参阅此内容.您可以编辑 gradle 选项文件(.gradle/gradle.properties 在您的用户文件夹中)并将 org.gradle.jvmargs=-Xmx2G 添加到它，或者您可以将选项变量设置为 -Xmx2G(在命令提示符下，运行 set GRADLE_OPTS=-Xmx2G，然后运行 ​​gradlew setupDecompWorkspace).

If you're using Minecraft Forge's ForgeGradle, see this. You can either edit the gradle options file ( .gradle/gradle.properties in your user folder) and add org.gradle.jvmargs=-Xmx2G to it, or you can set the options variable to -Xmx2G (in a command prompt, run set GRADLE_OPTS=-Xmx2G and then gradlew setupDecompWorkspace).

但是，鉴于您引用了 decompile.bat，您可能正在使用没有 Forge 的 MCP.(这很好，但伪造确实使模组更容易/更兼容；如果您要制作更永久的模组，而不仅仅是乱搞，您可能需要考虑这样做.)在这种情况下，您可以编辑 MCP 的配置以增加给定的内存.

However, given that you referenced decompile.bat, you probably are using MCP without Forge. (Which is fine but forge does make mods easier/more compatible; you may want to consider doing this if you're making a more permanent mod rather than just messing about.) In this case, you can edit MCP's configuration to increase the given RAM.

在 MCP 文件夹中，打开 conf 文件夹，然后使用您选择的文本编辑器打开 mcp.cfg.然后，找到这一行(靠近底部)

In the MCP folder, open the conf folder and then open mcp.cfg with a text editor of your choice. Then, find this line (near the bottom)

CmdFernflower = %s -jar %s -din=1 -rbr=0 -dgs=1 -asc=1 -log=WARN {indir} {outdir}

并将其替换为:

CmdFernflower = %s -Xmx2G -jar %s -din=1 -rbr=0 -dgs=1 -asc=1 -log=WARN {indir} {outdir}

(您可能需要更改其他行并在 -jar 之前添加 -Xmx2G 但它似乎从我的经验).

(You may need to change other lines also adding -Xmx2G before -jar but it doesn't seem to be needed from my experience).

这将运行带有额外 RAM 的反编译器.

This will run the decompiler with additional RAM.

或者，如果您不想弄乱 MCP 配置，MCP910 似乎没有这个问题.它适用于 1.8.0 而不是 1.8.8，但仍然可以满足您的需求.

Alternatively, if you don't want to mess around with the MCP configuration, MCP910 doesn't seem to have this issue. It works with 1.8.0 instead of 1.8.8, but should still do everything you want.
