組裝WAR日蝕時出錯

我正在使用Heroku部署我的eclipse項目。但是，當我嘗試運行我的項目作爲maven構建時，我得到一個錯誤。我到處尋找，但找不到解決方案。這是我得到的錯誤。組裝WAR日蝕時出錯

你heroku-maven-plugin插件配置似乎與maven-war-plugin混合。雖然該節的根部爲heroku-maven-plugin，但該配置包含對maven-war-plugin的引用，而不是在該節的根部添加maven-war-plugin。（Maven's'super pom'）構建/打包戰爭。Maven繼續使用它自己的maven-war-plugin參考（通過Maven的'超級pom'）來構建/打包戰爭。Maven不會使用它的maven-war-plugin參考。 ..和那插件是什麼扔錯誤。

如果您想在未找到web.xml時重新配置maven-war-plugin以使其不會失敗，則需要將POM中的<maven-war-plugin>移動到未嵌套在heroku-maven-plugin內的位置並將<failOnMissingWebXml>false</failOnMissingWebXml>移動到maven-war-plugin的<configuration>元素。

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-war-plugin</artifactId> 
    <configuration> 
     <failOnMissingWebXml>false</failOnMissingWebXml> 
    </configuration> 
</plugin> 
<plugin> 
    <groupId>com.heroku.sdk</groupId> 
    <artifactId>heroku-maven-plugin</artifactId> 
    <configuration> 
    ... 
    </configuration> 
</plugin>
