grails run-app随机抛出:java.lang.NoClassDefFoundError:Lorg/codehaus/groovy/grails/plugins/web/async/api/ControllersAsyncApi

Question

当我启动我的grails 2.2.0应用程序时,我随机收到如下错误消息,但它也随机成功启动,没有错误.没有更改代码,我只是尝试grails dev run-app多次运行.

$ grails dev run-app

我grails clean之前也试过了,但这没什么区别; 错误仍然随机发生.

启动错误:

环境:

• Mac OS X Lion
• JDK 1.6.0_31

类似的帖子,但仍然不同,因为我没有运行Tomcat:

• 在Tomcat6上运行的Grails应用程序 - 上下文初始化失败

Answer 1

将servlet版本从3.0更改为2.5(反之亦然)后出现此异常.

我输入以下内容解决了这个问题:

grails clean
grails clean-all

已再次获取依赖项并且应用程序开始运行.

Answer 2

尝试将servlet版本标记为v3.0.我有同样的零星问题,并通过转到v.3.0解决了它

文件:BuildConfig.groovy

grails.servlet.version ="3.0"//根据目标容器合规性(2.5或3.0)进行更改

之后grails-plugin-async-2.2.0.jar出现在classpath上:

%HOME%.grails \常春藤缓存\ org.grails \的Grails,插件,异步\罐\
