WSO2社区版 - 权限扩展

Question

我使用的是WSO2社区版。

我试图根据这个URL来添加权限扩展。https:/docs.wso2.commmobile.action#page97563684。

所以我从这里克隆GIT repo，然后做maven包。https:/github.comwso2-extensionsidentity-agent-entitlement-proxy。

但失败了，出现以下错误。

TID: [-1234] [] [2020-06-18 12:20:17,190] ERROR {org.wso2.carbon.registry.extensions.ui.AddExtensionProcessor} - File uploading failed. Content is not set properly.

如果有任何帮助或建议可以解决这个问题，我们将不胜感激。最后但并非最不重要的是，我是WSO2扩展编码的新手，谁能提供一个helloworld扩展也是感激的。
