有效解决方案 #

1. 替换为干净的XML文件 #

用纯文本编辑器（如Notepad++）创建新的XML文件，复制以下内容并保存为GvhProjectSettings.xml，覆盖原文件：

<?xml version="1.0" encoding="utf-8"?>
<projectSettings>
    <projectSetting name="Google.IOSResolver.VerboseLoggingEnabled" value="False" />
    <projectSetting name="Google.PackageManagerResolver.VerboseLoggingEnabled" value="False" />
    <projectSetting name="Google.VersionHandler.VerboseLoggingEnabled" value="False" />
</projectSettings>

保存时选择UTF-8无BOM编码，避免编码问题导致解析失败。

2. 自动重置配置文件 #

直接删除ProjectSettings/GvhProjectSettings.xml文件，重启Unity编辑器。Google Jar Resolver会自动重新生成该配置文件，大概率能解决解析问题。

3. 更新或重装Google Jar Resolver #

打开Unity的Package Manager，找到Google Jar Resolver相关包（可能显示为com.google.android.appbundle或类似名称），选择更新到最新版本；若更新无效，卸载后重新安装该包，修复可能存在的文件损坏或版本兼容问题。

4. 检查编辑器编码设置 #

在Unity编辑器中，依次打开Edit > Preferences > External Tools，确保外部脚本编辑器设置为支持UTF-8编码的工具（如VS Code、Notepad++），避免保存XML文件时引入无效字符。
