java.lang.NoSuchMethodError：org.apache.commons.logging.LogFactory

Question

當我為android啟用proguard時，proguard會混淆包含在應用程序中的所有jar。 這些罐子包括：

• libraryjars lib / Analytics_Android_SDK_2.1.jar
• libraryjars lib / commons-codec.jar
• libraryjars lib / commons-httpclient-3.1.jar
• libraryjars lib / commons-logging-1.1.jar
• libraryjars lib / weibo.jar
• libraryjars lib / signpost-core-1.2.1.1.jar
• libraryjars lib / signpost-commonshttp4-1.2.1.1.jar
• libraryjars lib / youmibannerad-android.jar

在構建已簽名的jar時，我得到以下轉儲：

    06-25 16:07:25.094: WARN/dalvikvm(13785): Exception Ljava/lang/NoSuchMethodError; own   while initializing Lorg/apache/commons/httpclient/HttpMethodBase;

實際上這個項目是關於新浪微博的SDK，當我使用proguard對它進行模糊處理時，我總是失敗，錯誤如下：

所以我將代碼-ignorewarnings添加到proguard配置文件中，所以警告全部被駁回，但是當我運行應用程序時，標題中的錯誤將會發生。

Answer 1

在一個外包項目中遇到同樣的問題，似乎開發人員已經使用了世界上所有可能的免費圖書館。

最安全的方法是為ProGuard提供原始庫作為參考，即使其中一些已被棄用且可能永遠不會被您的代碼調用：

Log4J - http://logging.apache.org/log4j/1.2/download.html

Avalon - http://www.docjar.com/jar_detail/avalon-framework-4.2.0.jar.html

Avalon LogKit - http://www.jarfinder.com/index.php/jars/versionInfo/17610

J2EE參考 - http://www.jarfinder.com/index.php/jars/versionInfo/4598

下載完所有的罐子后，將ProGuard指向他們：

# Apache commomns-logging fun

-libraryjars proguard_ref_lib/log4j-1.2.17.jar
-libraryjars proguard_ref_lib/avalon-framework-4.2.0.jar
-libraryjars proguard_ref_lib/avalon-logkit-2.2.1.jar
-libraryjars proguard_ref_lib/servlet-api-6.0.16.jar

# Apache commomns-logging fun ends

請享用

Answer 2

我會嘗試commons-logging-1.1.1。 似乎版本不匹配
