Question

我正在尝试通过运行grails tomcat deploy来通过tomcat插件部署Grails应用。这样做时效果非常好，除了WAR文件中的所有配置都是它们的开发值（例如，开发数据源试图从我部署的WAR文件中使用）。

然后我尝试运行grails prod tomcat deploy，并发生以下错误：

有谁知道为什么会这样？我正在使用Grails 2.4.4和Java 7u71。

对于tomcat 7+，您需要在tomcat-users.xml中为您的用户添加manager-script角色。

来自Grails Tomcat Plugin Docs：

Tomcat 7 如果您使用的是Tomcat 7，请确保用户具有manager-script角色

<user username="manager" password="secret" roles="manager-script" />

运行'grails tomcat deploy'时出现java.io.IOException
