在app自动更新过程中，有用到ionic-native插件：cordova-plugin-file-openner2 添加插件后，打包时有错：
FAILURE: Build failed with an exception. * What went wrong: A problem occurred configuring root project ‘android‘. > Could not resolve all dependencies for configuration ‘:_debugCompile‘. > Could not find any version that matches com.android.support:support-v4:+. Searched in the following locations: https://repo1.maven.org/maven2/com/android/support/support-v4/maven-metadata.xml https://repo1.maven.org/maven2/com/android/support/support-v4/ Required by: :android:unspecified * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
通过一番查询，可能是插件版本问题；
在这儿发现了解决办法-------->

好，于是就在 config.xml中做了如下更改：
改之前：
<plugin name="cordova-plugin-file-opener2" spec="~2.0.15" />
改之后（如果没有就添加打包的时候 项目会自动添加）：
<plugin name="cordova-plugin-file-opener2" spec="1.0.11" />
好吧----这就可以用了 打包成功！！
总结：自己太菜！
