我正在尝试在 Android 平台上构建一个 Ionic 应用程序，包括 ibm-mfp-push cordova pplugin 和 googlemaps cordova 插件。
从一个全新的 Ionic 应用程序开始，我首先导入了 cordova ibm-mfp-push 插件，然后 android 构建成功完成。
导入 cordova-plugin-googlemaps 后，gradle 构建中断并出现以下(频繁)异常:
:transformClassesWithDexForDebug
UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dex.DexException: Multiple dex files define Lcom/google/android/gms/internal/zzqm;

按照常见的方法，我在我的依赖树中查找所有导致冲突的模块:

最后我排除了以下模块:
configurations {
all*.exclude group: 'com.google.android.gms', module: 'play-services-analytics'
all*.exclude group: 'com.google.android.gms', module: 'play-services-appindexing'
all*.exclude group: 'com.google.android.gms', module: 'play-services-ads'
all*.exclude group: 'com.google.android.gms', module: 'play-services-gcm'
all*.exclude group: 'com.google.android.gms', module: 'play-services-plus'
all*.exclude group: 'com.google.android.gms', module: 'play-services-safetynet'
all*.exclude group: 'com.google.android.gms', module: 'play-services-wallet'
all*.exclude group: 'com.google.android.gms', module: 'play-services-wearable'
}
现在，构建成功终止，但我在运行时遇到 ClassNotFoundException:

我该如何解决我的问题？ 非常感谢您的帮助。
最佳答案
终于解决了修改Android项目中的project.properties文件，改了下面几行
cordova.system.library.1=com.google.android.gms:play-services-maps:9.2.0
cordova.system.library.2=com.google.android.gms:play-services-location:9.2.0
具有以下内容:
cordova.system.library.1=com.google.android.gms:play-services-maps:7.8.0
cordova.system.library.2=com.google.android.gms:play-services-location:7.8.0
关于java - Gradle "com.android.dex.DexException"构建涉及 cordova-plugin-googlemaps 和 ibm-mfp-push 插件的应用程序。，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38168891/
