使用Java客户端将文件添加到GitHub-org.eclipse.egit.github.core

Question

我正在尝试使用以下代码将文件添加到存储库，但出现以下错误。我现在只想添加一个文件。

org.eclipse.egit.github.core.client.RequestException：无效的请求。

对于'properties / email'，nil不是字符串。对于“属性/名称”，nil不是字符串。对于“属性/电子邮件”，nil不是字符串。对于'properties / name'，nil不是字符串。 （422）在org.eclipse.egit.github.core.client.GitHubClient.createException（GitHubClient.java:552）在org.eclipse.egit.github.core.client.GitHubClient.sendJson（GitHubClient.java:643）在org.eclipse.egit.github.core.client.GitHubClient.post（GitHubClient.java:757）在org.eclipse.egit.github.core.service.DataService.createCommit（DataService.java:397）

我感觉它正在期待一些属性，但是如何提供它尚不清楚。我想念的是什么？

Answer 1

经过一些调试后，发现电子邮件和名称值以null开头，这是问题的根源。

添加以下两行将解决此问题：

author.setName( userName );
author.setEmail(email);
