D:\appinventor-sources\appinventor\components\build.xml:230: Compile failed; see the compiler error output for details.

このエラーを引き起こすファイルは、ここにあります：

https://github.com/barreeeiroo/appinventor-sources/blob/master/appinventor/components/src/com/google/appinventor/components/runtime/VersionName.java

は、私はラインであることを考える：私は拡張モジュールをビルドする場合、そのライブラリをインポートするとき、それは誤りであるかのようにライン24

上 import android.content.Context;は、そのファイルにエラーがありません、私はimport android.content.pm.Contextを試みたが、ファイルの読み取り中にそれがクラッシュしたので、私はそれがあるJavacまたはJavaエラー、私はそれを修正するにはどうすればよい

であると仮定しているため？

通常、あなたはとても以降のバージョン名に

ところで 
@SimpleFunction(description = "Returns the version name of the app") 
    public String VersionName() { 
    Log.d(LOG_TAG, "VersionName"); 
    try { 
     PackageInfo pInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), 0); 
     String version = pInfo.versionName; 
     return version; 
    } catch (NameNotFoundException e) { 
     Log.e(LOG_TAG, e.getMessage()); 
     e.printStackTrace(); 
     return ""; 
    } 
    }

を取得するには、このスニペットを使用することになり、この

public class TaifunTools extends AndroidNonvisibleComponent { 
    private static Context context; 
    private static final String LOG_TAG = "TaifunTools"; 

    public TaifunTools(ComponentContainer container) {  
    super(container.$form()); 
    this.container = container; 
    context = (Context) container.$context(); 
    }

のようなコンテキストを取得します。 App Inventorのソースを操作に関する質問について、最高の場所はApp Inventor Open Source forumに依頼することです...

もApp Inventor Extensions documentを参照してexample extensions provided by MIT.に見..
