maven軟件倉庫：方法中缺少代碼屬性

Question

我一直在開發一個spring/hibernate項目，我正在嘗試移動到maven。我在運行build時遇到了一個令人討厭的問題。

正如你會問它，我目前的pom.xml爲available on github，異常跟蹤如下所示：

我嘗試添加一些依賴我在谷歌找到，但他們導致另一個奇怪的例外。我在mkyong.com閱讀，這可能是因爲java文件不包含方法體，但我檢查了javaee-api包，它具有javax.transaction.SystemException類實現。

Answer 1

原來的JavaEE的Web-API缺少一些方法體，這就是爲什麼以下的pom.xml依賴：

<dependency> 
    <groupId>javax.servlet</groupId> 
    <artifactId>servlet-api</artifactId> 
    <version>2.5</version> 
    <scope>provided</scope> 
</dependency> 

和它的作品：

<dependency> 
    <artifactId>javaee-web-api</artifactId> 
    <groupId>javax</groupId> 
    <version>6.0</version> 
    <scope>provided</scope> 
</dependency> 

應改爲精細。
