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 mod。但总是当我反编译它时，我得到一个错误

有谁知道如何解决此错误？：d

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，找到这条线（在底部附近）

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

并替换为：

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，还需要在-jar之前添加-Xmx2G，但是根据我的经验，似乎不需要。）

这将运行带有额外RAM的反编译器，这应该可以解决此问题。

反编译MCP错误（版本9.18）返回＆＃39;反编译失败＆＃39; 1
