java - 反编译MCP报错(9.18版)返回 'Decompile Failed' 1

Question

我有一个 64 位系统并使用 64 位 Java 版本。

我想用 mcp 做一个 minecraft 模组。但是在反编译的时候总是报错

有谁知道如何解决这个错误？ :D

Answer 1

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)

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，但根据我的经验似乎不需要)。

这将使用额外的 RAM 运行反编译器，这应该可以解决这个问题。
