Gradle 在为“targetApi"合并清单时失败； [英] Gradle fails on manifest merging for "targetApi"

问题描述

我的项目在清单中包含使用 tools:targetApi 属性忽略一些警告的活动声明.具体:

My project contains activity declarations in the manifest that use the tools:targetApi attribute to ignore some warnings. Specifically:

    <activity
        android:name=".activities.ProtocolActivity"
        android:label="@string/title_activity_protocols"
        android:parentActivityName=".activities.InformationActivity"
        tools:targetApi="jelly_bean">
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value=".activities.InformationActivity" />
    </activity>

然而，突然之间，例如在切换分支后，我收到以下编译错误:

Out of the blue, however, for instance after switching branches, I get the following compilation error:

错误:/home/paul/git/ally-v2-app/app/src/main/AndroidManifest.xml:67:9-80:20:错误:无效指令targetApi"，有效指令为:删除，替换，严格
...
错误:java.lang.IllegalArgumentException:否枚举常量 com.android.manifmerger.AttributeOperationType.TARGETAPI

Error:/home/paul/git/ally-v2-app/app/src/main/AndroidManifest.xml:67:9-80:20: Error: Invalid instruction 'targetApi', valid instructions are : REMOVE,REPLACE,STRICT
...
Error:java.lang.IllegalArgumentException: No enum constant com.android.manifmerger.AttributeOperationType.TARGETAPI

我正在使用以下内容:

• Gradle 2.10
• Gradle 插件 2.0.0-beta6
• Android Studio 2.0 测试版 6
• 在 Ubuntu 15.10 机器和 Windows 10 机器上

似乎我可以通过清除缓存并重新启动 Android Studio 或删除属性、构建然后再次添加它们来使事情再次运行.

It seems I can get things working again by clearing the cache and restarting Android Studio, or removing the attributes, building, then adding them again.

推荐答案

替换为

tools:ignore="UnusedAttribute"

还修复 lint 问题.
