Error:Artifact 'xx.war exploded' has invalid extension

环境信息：  IDEA 13 ,  MAVEN, JBOSS 7.

配置信息： 常规配置。

出错信息： Error:Artifact 'xx.war exploded' has invalid extension

原因： 出现这种错误的原因是 build 打的 war 包不正确造成的， 修改 pom.xml build war 包部分代码既可。

代码如下：

 <plugin>
       <artifactId>maven-war-plugin</artifactId>
       <configuration>
             <webappDirectory>${project.build.directory}/${project.artifactId}.${project.packaging}</webappDirectory>
             <failOnMissingWebXml>false</failOnMissingWebXml>
       </configuration>
</plugin>

mvn clean package ，后错误信息就不在了。

Actually, you should leave the finalName attribute alone, otherwise you'll get the problems you describe. Rather, you should change the config for the maven war plugin to use the webappDirectorylike this:

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <configuration>
        <webappDirectory>${project.build.directory}/${project.artifactId}.${project.packaging}</webappDirectory>
        <failOnMissingWebXml>false</failOnMissingWebXml>
    </configuration>
</plugin>
