Maven tomcat7僅執行戰爭錯誤

[英]Maven tomcat7 exec-war-only Error

 原文  2014-06-09 17:17:06  7   5    java/ maven/ tomcat

問題描述

我想創建一個可執行的war / jar，如tomcat7-maven-plugin文檔中所述： http : //tomcat.apache.org/maven-plugin-2.2/executable-war-jar.html

但是我得到一個構建失敗（NullPointerException）：

目標tomcat7：deploy ， ：redeploy和：undeploy以及使用tomcat7：run啟動本地嵌入式服務器的運行均符合預期。

附加信息：我使用Eclipse Kepler，我的運行配置如下所示：
tomcat7：exec-war -e
我也嘗試了突擊隊，嘗試了：exec-war-only，但是沒有任何效果。

我已經搜索並嘗試了幾天的嘗試，所以對您的幫助非常感謝！ ：]

5 個解決方案

解決方案1
 2 已采納  2014-06-14 13:12:14

我對該插件的2.2版有類似的問題，但是根據本教程，它可以與2.1版一起運行。

解決方案2
 2  2016-07-24 00:58:13

現在有一個2.3版，其中的2.2版問題已修復！

（因為2.1太舊了，所以在2.1上有一些問題）

遺憾的是，它只是一個快照版本，需要從Apache Snapshots存儲庫中獲取。 要獲取它，您需要將其放入pom中： 

<pluginRepositories>
    <pluginRepository>
        <id>apache.snapshots</id>
        <name>Apache Snapshots</name>
        <url>http://repository.apache.org/snapshots</url>
        <releases>
            <enabled>false</enabled>
        </releases>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </pluginRepository>
</pluginRepositories>

然后，您可以使用新版本 <version>2.3-SNAPSHOT</version>

解決方案3
 2  2016-11-14 19:10:36

NPE是因為插件找不到打包的war文件，因此我通過將package階段顯式添加到內部版本中來修復該錯誤，例如： 

mvn clean package tomcat7:exec-war

產生戰爭包裝的任何階段都非常適合避免NPE：包裝，安裝，部署等。

因此，如果您在Eclipse中使用“運行配置”，只需在tomcat7:exec-war -e之前添加package

解決方案4

我在Spring Boot應用程序中收到此錯誤。 我不得不花一些時間，因此將其放在此處需要包含以下插件 

   <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
    </plugin>

另外包裝類型應該是罐子 

<packaging>jar</packaging>

入門班應定義為您的主要班級 

<start-class>com.edu.schoolT.SchoolWeb</start-class>

主類或帶有@SpringBootApplication注釋的類應擴展SpringBootServletInitializer。 有關更多信息... 創建可部署的戰爭文件

我已經在項目中修復了類似的問題，並在下面的鏈接中提供了參考
