grails - 运行Grails AWS插件时出现ClassNotFoundException

Question

我在Grails 2.2.2上使用Grails AWS插件:https://github.com/grails-aws/grails-aws。我无法使用基本的S3文件上传功能。我收到以下错误:

错误日志:

这是BuildConfig:

compile ":aws:1.6.7.5"

Controller :

file.inputStream.s3upload(newFilename) {
   path "pictures/"
}

因此，这里没有什么特别的事情，只是基本配置，但是它不起作用。有任何想法吗？

UDPATE:

运行依赖性报告，以确保该应用程序正在使用HTTPClient 4.2，并且它是:

httpclient by org.apache.httpcomponents 4.2 4.1.2

谢谢

从Maven可以看出，Grails AWS插件使用的AWS SDK 1.6.7依赖于Apache HttpClient 4.2。

请在您的BuildConfig.groovy中添加以下依赖项:

runtime 'org.apache.httpcomponents:httpclient:4.2'
