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

我从昨天开始遇到麻烦了.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.

这是cordova插件列表的输出,我没有support-v4 / v13冲突,你可以看到：

$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"

这里还有一些更多的信息：

$cordova -v
7.0.1

$ionic -v
2.1.4

解决方法:

您最有可能使用新发布的cordova-android@6.3.0,现在包含BuildHelper.java(如您的错误消息中所述)和PermissionHelper.java,但您的项目中仍然使用了已弃用的cordova-plugin-compat,导致构建失败,因为它also contains these classes.

要解决此问题,请从项目中删除cordova-plugin-compat以从cordova-android平台项目中卸载这些Java文件::

cordova plugin rm cordova-plugin-compat --force

更新

要保留此更改,请添加cordova-plugin-compat@1.2,其中包含engine constraint,以防止将Java文件重新安装到cordova-android@6.3平台中：

cordova plugin add cordova-plugin-compat@1.2

另一个更新(从评论中复制)

删除并添加cordova-plugin-compat@1.2后,您只能从文件夹平台/ android中删除文件BuildHelper.java和PermissionHelper.java,而不是删除和添加整个Android平台
