任務'：app：preDexDebug'的執行失敗。 > com.android.ide.common.process.ProcessException：

Question

我正在嘗試將apache POI庫與我的android應用程序集成。爲此，我已經將apache poi jar文件添加到我的libs文件夾中，並使用「編譯文件」來編譯通過build.gradle。但是當我進行gradle同步時，它沒有問題。在進行gradle同步之後，當我嘗試運行應用程序時，我得到錯誤執行失敗的任務'：app：preDexDebug'。

我見過以下類似的問題，但沒有用。

Error: Execution failed for task ':app:preDexDebug'

https://stackoverflow.com/questions/27437049/android-studio-gradle-execution-failed-for-task-apppredexdebug

以下是我gradle這個依賴：

dependencies { 
compile fileTree(include: ['*.jar'], dir: 'libs') 
compile 'com.android.support:appcompat-v7:22.1.1' 
compile files('libs/poi-3.12-20150511.jar') 
compile files('libs/poi-ooxml-3.12-20150511.jar') 
compile files('libs/poi-ooxml-schemas-3.12-20150511.jar') 
compile files('libs/xmlbeans-2.6.0.jar') 
} 

錯誤消息：

Error:Execution failed for task ':app:preDexDebug'. 
> com.android.ide.common.process.ProcessException:org.gradle.process.internal.ExecException: 
    Process 'command 'C:\Program Files\Java\jdk1.8.0_31\bin\java.exe''

1. 你試試下面的序列（按順序）：無效緩存&重啓=> gradle這個同步=> gradle這個乾淨= > gradle構建？

2. 在File => Project Structure => SDK Location中：您是否將JDK位置設置爲指向JDK 7的有效安裝？

3. 你在模塊的build.gradle這是觸發錯誤有這樣的：

   android { 
       ... 
       compileOptions { 
        sourceCompatibility JavaVersion.VERSION_1_7 
        targetCompatibility JavaVersion.VERSION_1_7 
       } 
   } 
   

Answer 2

我卡住了這個錯誤，這兩天，我終於deceided尋找替代方法在android應用程序中創建Excel表格。

我曾嘗試使用「aspose」庫，與「apache Poi」和「jxl」庫相比，它非常易於使用。

「Aspose」的相關鏈接庫以及如何在android項目中使用。
