嘗試從Eclipse部署戰爭給Wildfly 8時出現NullPointerException

當我嘗試直接從Eclipse部署war到WildFly時，出現錯誤。這隻發生在我從Eclipse部署war時，當我將戰爭手動複製到Wildfly的standalone/deployments目錄時，沒有任何問題。嘗試從Eclipse部署戰爭給Wildfly 8時出現NullPointerException

昨天工作，自那時以來沒有發生應用程序配置更改（沒有新的maven依賴關係，沒有更改web.xml,persistence.xml等），只是一些代碼修改。有一些Java 8代碼被添加，也許這可能是問題。但之前我們在項目中有Java 8的代碼，這不是問題。

你有沒有嘗試刪除空的''標籤？ – 2014-10-03 21:14:19

你可以發佈你的pom.xml嗎？我懷疑;）你怎麼從日食部署戰爭？使用M2E插件還是Run On Server操作？ – shillner 2014-10-06 06:28:23

@ JamesR.Perkins，試圖刪除空的標記，沒有幫助 – Ievgen 2014-10-06 07:02:52

有了您的上述評論似乎是，我已經似乎幾次同樣的問題。我會盡力向您解釋：

您正在使用maven構建您的項目並打包WAR。在使用maven構建和部署WAR包的情況下，一切都很好，並且您的應用程序按照預期在服務器上運行。如果使用eclipse上的Run on Server特性，你總會得到異常，這些異常也可能因項目狀態而異（使用maven構建，在eclipse中更改了一些內容，清理了項目並使用eclipse構建...））這可能是由Eclipse執行的構建步驟與maven完成的構建步驟不兼容造成的。我認爲你可能在你的pom中有一些沒有被eclipse「builders」覆蓋的構建步驟，因此錯過了這些步驟會導致不同的錯誤，這取決於你是否在部署之前使用maven構建了項目，以及你結盟的變化類型。

對不起，如果這聽起來有點混亂，但很難解釋這種行爲。最好是去嘗試一些不同的工作流程，如：

用Maven構建
與Maven部署（一切都應該工作）
取消部署和改變一些源代碼
與Eclipse部署（可用）

並分析你的pom（s）如果有一些構建步驟看起來像這些不能通過eclipse覆蓋沒有maven。

問題的描述看起來非常類似於正在發生的事情..但我沒有看到我的任何東西可能不會被eclipse覆蓋。此外，我有一個類似的項目，完全相同的POM，它沒有問題。 – Ievgen 2014-10-06 13:00:07

沒有了我們所能做的只是猜測。嘗試設置一個顯示此行爲的簡單示例並將其發佈。如果您無法創建一個具有相同問題的小型項目，請發佈項目的pom。如果POM遞歸引用父項，可能從您的項目的實際項目開始，然後添加下面的有效POM。 – shillner 2014-10-06 13:54:16

應該發佈具有依賴性的pom，或者您認爲依賴關係在這裏並不重要？ – Ievgen 2014-10-06 14:42:37

我也遇到了同樣的問題，似乎Maven構建和Eclipse部署方式之間存在一些不匹配。以某種方式部署已損壞，不允許再次部署並給予NullPointer。我通過從Eclipse中刪除JBoss並再次添加它來解決它，再次更新我的一些自定義配置並開始。有效。它是一種解決方法，但解決了我的問題。
