我試圖移動到maven作爲構建系統，以便對依賴關係進行更加標準的管理。NetBeans 7.2，啓動一個maven spring項目並添加休眠
這是我所做的步驟以及我問的簡單的（maven newbie）問題。這個過程是最直接的，我可以immagine，所以這個問題應該很容易重現。
- 讓我們從File，New Project，Maven，Web Application開始吧。 在以下表格中，我保留了所有默認值，但是保留了我選擇「Apache Tomcat 7.0.11.0」的應用程序服務器字段。 我注意到這個嚮導沒有提出任何框架（Sring，Hibernate等），而標準的非Maven項目創建嚮導確實允許框架的選擇包含。
如果我們看一下現在的項目，這裏就是我們看到：
因此，第一個問題是：爲什麼春天已經包含，在那之前我」已明確添加它？
讓我們看看項目屬性：
所以沒有框架被選中。 我想使用彈簧只是爲了它的依賴注入容器（稍後我可能會添加彈簧安全性，但這不是此時的優先事項）。 我是否需要重新添加它，因爲如上所述，一些核心模塊已包含在內？
- 在項目屬性中，在框架節點中，我添加了Hibernate並選擇了一個數據庫連接。依賴現在變成如下。
他們兩個（我在截圖中作了重點介紹）被標記爲「依賴尚未下載。建設項目以糾正錯誤」（你可以看到這個消息的提示當你將指針移到它們上面時）。我已經構建了該項目，但錯誤仍然存在。
在行家的輸出，我看到：
Failed to execute goal on project CreatingMavenSpringProject: Could not resolve dependencies for project com.mycompany:CreatingMavenSpringProject:war:1.0-SNAPSHOT: The following artifacts could not be resolved: javax.sql:jdbc-stdext:jar:2.0, javax.transaction:jta:jar:1.0.1B: Could not find artifact javax.sql:jdbc-stdext:jar:2.0 in unknown-jars-temp-repo (file:C:\Users\agostino\Documents\NetBeansProjects\CreatingMavenSpringProject/lib) -> [Help 1] To see the full stack trace of the errors, re-run Maven with the -e switch. Re-run Maven using the -X switch to enable full debug logging.
我試過，因爲它表明：

現在我停留在這一點上，請注意，這是您嘗試添加休眠時maven項目的開箱即用行爲。如何解決這個問題？
您可以顯示由Netbeans中產生的pom.xml的錯誤？ – AgostinoX
@AgostinoX我已經添加了兩個。 – madth3
