[Bug] 自动选择 Java 功能为 LabyMod 选择了错误的 Java 版本

[suchen2011]

问题描述 | Bug Description

先说起因，不想看请跳到第二自然段。我在网上下载了一个labymod的离线版，因为PCL-CE让我使用正版启（PCL都不用正版，看来是把原有的功能删了，以后再也不用PCL-CE了）所以我就开始用HMCL了
我用的是今天官网最新下载的开发版，启动时，我勾选自动选择合适的JAVA（如图一所示），但日志中“LabyMod4 was started with an outdated Java version (1.8.0_451). Please use Java 17 or higher.”（如上传附件所示），但我如果手动选择JAVA17.0.4就能正常启动，希望修复
最后说下，我一般不看GitHub，有什么材料没交全的可找B站，与GitHub同名同头像，说不定还在看你的直播呢（dog）

我用官网安装器装了个 LabyMod 端 (“Launcher” 选“Minecraft Launcher”)，可以复现问题。实例设置中 Java 选项自动选择的情况下，显示选择了 Java 21，但启动游戏直接用了 Java 8。手动选择 Java 21 后，可以进入游戏主界面。

因为PCL-CE让我使用正版启（PCL都不用正版，看来是把原有的功能删了，以后再也不用PCL-CE了）所以我就开始用HMCL了

虽然可能有点扫兴，但说明一下，PCL CE 没有移除“离线登录”，和 PCL、HMCL 一样都要先登录正版才能使用离线登录。PCL-Community/PCL-CE#1954, PCL-Community/PCL-CE#2445, PCL-Community/PCL-CE#2639

实例设置中 Java 选项自动选择的情况下，显示选择了 Java 21，但启动游戏直接用了 Java 8。

？？？您能否看下 version json 中存储的 Java 版本信息。如果存储的是 Java 21，那大概是 Java 选择器的问题，那一块我不熟悉，得找 @Glavo

？？？您能否看下 version json 中存储的 Java 版本信息。如果存储的是 Java 21，那大概是 Java 选择器的问题

我用 LabyMod 4 官方提供的 JAR 进行了一次安装，实例 JSON 的 javaVersion 提供的确实是 Java 21。

值得注意的是，HMCL 似乎无法识别这个实例的 MC 版本（显示为未知），同时自动选择设置确实选到了 Java 8。

测试用的 HMCL 版本：3.17.0.352

EDIT: 附上一份实例 JSON

LabyMod-4-1.20.1-snapshot.json

[3gf8jv4dv]

值得注意的是，HMCL 似乎无法识别这个实例的 MC 版本（显示为未知）

就我测试的情况来说，成功启动一次游戏后就能识别了。

[suchen2011]

为什么我不行，可能是我下载的不是官方版的原因，但是PCL官方版可以识别啊

不，不是那个问题他的提示是这样的

[3gf8jv4dv]

不，不是那个问题他的提示是这样的

关键词 “当前实例要求”。

在 “实例设置” > “设置” 里找找选项。说太多就跑题了。

labymod官网好像有说这个问题

什么是"官方版"? 指的是启动器吗? 如果是 那你的启动器是在哪来的?

[Minecraft269]

labymod官网好像有说这个问题

"Jar"版是允许非正版玩家启动的 且可以正常游玩 只是一些功能受到限制

[3gf8jv4dv]

labymod官网好像有说这个问题

这个是 LabyMod 的要求。楼主的描述是 PCL CE 给挡了下来。
