使用Maven進行錯誤構建

Question

在Eclipse下，我剛剛對Java代碼進行了一些更改，然后，我自動進行了Clean / Build（清理我的4個項目），然后對包含入口點的項目進行GWT編譯（該項目的GWT編譯） ，最后導出包含入口點（導出/戰爭文件）的項目的WAR。 我必須將WAR放在Jonas服務器的目錄webapps / autoload中。 我停止Jonas服務器，然后重新啟動Jonas服務器。

問題是：當我通過Internet Explorer到達應用程序服務器時，我的代碼的最新更改不存在。 但是，當我在localhost：8080中執行應用程序時，它們存在。

我懷疑我的WAR是根據先例編譯創建的。 您是否認為這是問題所在？ 而且我看到一個問題：當我清理項目時，對於3個項目，我有這個非常普遍的錯誤：

27/09/12 20:16:36 CEST: Build errors for my_project;
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal
org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project alizesWeb: Compilation failure

首先，我該如何解決這個非常籠統且無法解釋的錯誤？

其次，您是否認為此錯誤是我的問題的原因（沒有我的最后更改的應用程序）。

第三，如果沒有，我該怎么做才能將修改后的內容集成到應用程序中？

這是Maven控制台的全部內容：

在構建我的工作區的4個項目之前，它會停止。
在此Maven控制台中，以粗體顯示的是，我的工作區中至少有兩個項目alizesWeb和clas2coreGwt，其中一個存在構建錯誤。
我問我這些錯誤是否與上述問題無關（我的最新更改未放在我的應用程序服務器中）

這是寫在“日志錯誤”視圖中的錯誤：

編譯失敗意味着您的代碼無法編譯，因此這是沒有可行的jar / war的原因，是的。

Eclipse應該在問題所在的“問題”視圖（窗口->打開視圖）中告訴您。 該消息很籠統，就像您說的那樣，因此您需要找出詳細信息才能進行修復。
