Question

我有一个grails应用程序，它在Windows中运行得非常好，并且在作为WAR文件部署到Amazon弹性beanstalk时也是如此。但它不会在亚马逊EC2机器上运行。为什么会这样？这是我尝试运行时获得的输出：

Answer 1

grails-set-version似乎对我有用。

我认为发生的事情是您没有按照升级说明进行操作：

http://grails.org/doc/2.4.x/guide/upgradingFrom23.html

你需要升级你的脚手架版本（以及其他一些东西），但是使用你创建项目的版本可以使用，但是如果要升级到2.4，你需要按照这些说明进行操作。 / p>

Answer 2

您是否可以使用grails-set-version更改grails版本？我发现这对Ec2不起作用。您需要继续使用最初开始使用的grails版本。试试吧。

Answer 3

当我将 Grails 应用程序从 2.3.11 移动到 Grails 2.5.6 时，出现以下错误：

Compilation error: startup failed:
Compile error during compilation with javac.
/Users/brippe/Projects/server/server/target/work/plugins/scaffolding-2.0.3/src/java/org/codehaus/groovy/grails/scaffolding/view/ScaffoldingViewResolver.java:42: error: no interface expected here
public class ScaffoldingViewResolver extends GrailsViewResolver {
                                             ^
/Users/brippe/Projects/server/server/target/work/plugins/scaffolding-2.0.3/src/java/org/codehaus/groovy/grails/scaffolding/view/ScaffoldedGroovyPageView.java:75: error: method does not override or implement a method from a supertype
    @Override

为了修复这些错误，我将脚手架插件从 2.0.3 更改为 2.1.2：

plugins {
        build: ..
        compile ":scaffolding:2.1.2" 
}

更改到 2.1.2 版本后，错误消失了。

Grails应用程序不会在Amazon EC2中运行，但在Windows中运行良好
