尝试将战争部署到heroku 使用maven 3.2.5
mvn clean heroku:deploy-war
获得此例外：

答案 0 :(得分：2)
Heroku appName配置中的plugin不正确。 Heroku应用程序必须以字母开头，并且只能包含小写字母，数字和短划线。因此MyApp无法正确。
检查Heroku仪表板中的应用程序页面，找到应用程序的名称，然后相应地更新配置。以下是带有随机命名的Heroku应用程序的插件配置示例：
<plugin>
<groupId>com.heroku.sdk</groupId>
<artifactId>heroku-maven-plugin</artifactId>
<version>0.3.0</version>
<configuration>
<appName>hidden-badlands-1234</appName>
</configuration>
</plugin>
