Capacitor Keyboard插件加载失败，抛出PluginLoadException异常求助

各位好，我是刚接触Capacitor和Android开发的新手，最近在集成@capacitor/Keyboard插件时卡壳了，想请大家帮忙分析下问题：

我先是按照常规步骤操作：

• 执行npm install --save-dev @capacitor/Keyboard安装插件
• 运行npx cap sync同步项目，过程里显示成功识别到@capacitor/keyboard@7.0.1，全程没有报错

但当我在Google Pixel 8a真机上测试应用时，发现这个插件根本加载不起来。查看Logcat后，抓到了这样的异常栈：

Error loading plugins. com.getcapacitor.PluginLoadException: Could not find class by class path: com.capacitorjs.plugins.keyboard.KeyboardPlugin

我已经试了好几种办法试图解决，但都没效果：

• 卸载插件后重新安装，再执行npx cap sync
• 清除Android Studio的缓存并重启，然后用./gradlew clean清理项目

另外我也仔细检查了相关配置和文件：

1. capacitor.plugins.json里的插件配置是正确的：

[
  {
    "pkg": "@capacitor/keyboard",
    "classpath": "com.capacitorjs.plugins.keyboard.KeyboardPlugin"
  }
]

2. capacitor.build.gradle中也正确引入了依赖：

android {
  compileOptions {
    sourceCompatibility JavaVersion.VERSION_21
    targetCompatibility JavaVersion.VERSION_21
  }
}
apply from: "../capacitor-cordova-android-plugins/cordova.variables.gradle"
dependencies {
  implementation project(':capacitor-keyboard')
}
if (hasProperty('postBuildExtras')) {
  postBuildExtras()
}

3. 插件的核心Java文件Keyboard.java和KeyboardPlugin.java确实存在于node_modules/@capacitor/keyboard/android/src/main/java/com/capacitorjs/plugins/keyboard路径下

我的环境版本信息：

• @capacitor/android：7.4.1
• @capacitor/core 和 @capacitor/cli：7.4.2

实在搞不懂哪里出问题了，希望有经验的朋友能给点思路，谢谢大家！
