多个 dex 文件定义 Lorg/apache/cordova/BuildHelper

从昨天开始我就遇到麻烦了。在我的实习中，我遇到了以下构建错误，但我无法理解为什么：

$ cordova build android

[...]

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexException: Multiple dex files define Lorg/apache/cordova/BuildHelper;

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

这是输出cordova plugins list，我没有 support-v4/v13 冲突，如您所见：

$ cordova plugin list
com.googlemaps.ios 2.2.0-fixed "Google Maps SDK for iOS"
com.moust.cordova.videoplayer 1.0.1 "Video Player"
cordova-plugin-camera 2.4.1 "Camera"

cordova-plugin-statusbar 2.2.2 "StatusBar"

{}

这里还有一些更多信息：

$ cordova -v

您很可能正在使用新发布的[email protected] /cdn-cgi/l/email-protection，现在包括构建助手.java https://github.com/apache/cordova-android/blob/master/framework/src/org/apache/cordova/BuildHelper.java（如您的错误消息中所述）和PermissionHelper.java https://github.com/apache/cordova-android/blob/master/framework/src/org/apache/cordova/PermissionHelper.java，但你仍然有已弃用的科尔多瓦插件兼容 https://github.com/apache/cordova-plugin-compat在您的项目中，这导致构建失败，因为它还包含这些类 https://github.com/apache/cordova-plugin-compat/tree/master/src/android.

要解决此问题，请删除cordova-plugin-compat从您的项目中卸载这些 Java 文件cordova-android平台项目::

cordova plugin rm cordova-plugin-compat --force

Update

要保留此更改，请添加[email protected] /cdn-cgi/l/email-protection其中包括一个发动机约束 https://github.com/apache/cordova-plugin-compat/blob/master/plugin.xml#L29以防止 Java 文件被重新安装到[email protected] /cdn-cgi/l/email-protection+平台：

cordova plugin add [email protected] /cdn-cgi/l/email-protection

另一个更新（评论里复制粘贴的）

删除并添加后[电子邮件受保护] /cdn-cgi/l/email-protection，您只能从文件夹platforms/android中删除文件BuildHelper.java和PermissionHelper.java，而不是删除和添加整个Android平台
