Audrey So updated CB-13486:
---------------------------
Labels: reproduced triaged (was: )
> <config-file> adds duplicate element if the existing element has extra
> attributes
> ---------------------------------------------------------------------------------
>
> Key: CB-13486
> URL: https://issues.apache.org/jira/browse/CB-13486
> Project: Apache Cordova
> Issue Type: Bug
> Components: cordova-common
> Affects Versions: 2.1.1
> Reporter: Ibrahim M. Ghazal
> Labels: reproduced, triaged
>
> If {{<config-file>}} tries to add an element to a config file, and that
> config file has the same element but with extra attributes, the element is
> added anyway. I expect it to consider it already existing and skip adding it.
> Example:
> 1. Add {{cordova-plugin-file}} plugin, which contains this line in
> {{plugin.xml}}:
> {code}
> <config-file target="AndroidManifest.xml" parent="/*">
> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
> />
> </config-file>
> {code}
> 2. Since {{WRITE_EXTERNAL_STORAGE}} is not required on Android API 19+
> (Android 4.4+), I want to add {{android:maxSdkVersion="18"}} to the
> permission. So I add this to the app's {{config.xml}}
> {code}
> <edit-config file="AndroidManifest.xml" mode="overwrite"
> target="/manifest/uses-permission[@android:name='android.permission.WRITE_EXTERNAL_STORAGE']"
> xmlns:android="http://schemas.android.com/apk/res/android";>
> <uses-permission android:maxSdkVersion="18"
> android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
> </edit-config>
> {code}
> 3. Run {{cordova run android}}. It succeeds the first time and the permission
> is modified correctly. {{AndroidManifest.xml}} now contains this:
> {code}
> <uses-permission android:maxSdkVersion="18"
> android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
> {code}
> 3. Run {{cordova run android}} again. The {{<config-file>}} from
> {{cordova-plugin-file}} is applied again. It searches for the exact element
> it wants to add and doesn't find it (because that element now has an extra
> attribute, {{android:maxSdkVersion}}), and so it adds it again.
> {{AndroidManifest.xml}} now contains this:
> {code}
> <uses-permission android:maxSdkVersion="18"
> android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
> {code}
> This causes {{cordova run android}} to fail with:
> {code}
> Element uses-permission#android.permission.WRITE_EXTERNAL_STORAGE at
> AndroidManifest.xml:20:5-81 duplicated with element declared at
> AndroidManifest.xml:18:5-108
> See http://g.co/androidstudio/manifest-merger for more information about the
> manifest merger.
> {code}
