詹金斯拉請求插件拋出一個ArrayIndexOutOfBoundsException異常

Question

當我能夠在一個詹金斯項目的選項Use github hooks for build triggering，並儘量節省，我得到以下異常：

我不知道爲什麼會這樣。有沒有人有想法？在合併pull請求的基礎上工作得很好。如果我禁用該選項，我可以保存該項目，無任何例外。

非常感謝！

發生故障的方法是這樣的一個和用於ArrayIndexOutOfBoundsException的唯一原因，可以正確格式化（無/）或缺失（空）的令牌：

public GHRepository getRepository(String name) throws IOException { 
    String[] tokens = name.split("/"); 
    return retrieve().to("/repos/" + tokens[0] + '/' + tokens[1], GHRepository.class).wrap(this); 
} 

這裏是鏈接到源：https://github.com/kohsuke/github-api/blob/master/src/main/java/org/kohsuke/github/GitHub.java

插件文檔爲github提供了以下示例（並且從堆棧跟蹤中可以看到GitHub失敗）：

remote { 
    github('test-owner/test-project') 
    refspec('+refs/pull/*:refs/remotes/origin/pr/*') 
} 

我懷疑remote.github必須是包含單斜槓的格式。
