在cordova-android的CordovaLib編譯上找不到符號ClientCertRequest

Question

我目前正在構建一個 PhoneGap 應用程序，具有以下工具版本：

npm@2.5.1
cordova@3.6.0-0.2.9
cordova-android@3.6.0

為了安裝需要cordova-android v4+的插件，我嘗試安裝：

cordova@5.1.1
cordova-android@4.0.2

但是， cordova build命令不再起作用。 以下是引用編譯錯誤的第一行：

import android.webkit.ClientCertRequest;
                     ^

    private final ClientCertRequest request;
                  ^
  symbol:   class ClientCertRequest
  location: class CordovaClientCertRequest

據我了解， ClientCertRequest 符號是由 Android API 級別 21 引入的，我的cordova build正在嘗試使用較舊的級別進行編譯。

我試圖強制使用 API 級別 21。

文件/Users/Pierre/Documents/project/platforms/android/CordovaLib/project.properties包含以下內容：

split.density=false
# Project target.
target=android-19
apk-configurations=
renderscript.opt.level=O0
android.library=true

所以我嘗試創建一個兄弟文件ant.properties其中包含：
