克隆遠程存儲庫失敗使用JGit的http url

Question

這裏的問題是，URL被重定向，而不是在JGit中處理。沒有報告相同的錯誤，也提到它們已經解決，但我仍然面臨這個問題。請讓我知道如果我做錯了什麼。運行代碼

org.eclipse.jgit.api.errors.TransportException: 'http://github.com/google/mathfu': 301 Moved Permanently

改變下面的代碼

後後

代碼段

private static Git cloneRepository(String url, String branch, String targetPath) throws IOException { 
    Git result = null; 
    try { 
     CloneCommand cloneCommand = Git.cloneRepository().setCloneSubmodules(true) 
             .setURI(url).setBranch(branch) 
             .setCloneSubmodules(true) 
             .setDirectory(new File(targetPath)); 
     result = cloneCommand.call(); 
    } catch (GitAPIException e) { 
     e.printStackTrace(); 
    } 
    return result; 
} 

public static void main(String[] args) throws IOException { 
    cloneRepository("http://github.com/google/mathfu", "master", "D:/codebase"); 
    //cloneRepository("https://github.com/google/mathfu", "master", "D:/codebase"); 
} 

異常

//cloneRepository("http://github.com/google/mathfu", "master", "D:/codebase"); 
cloneRepository("https://github.com/google/mathfu", "master", "D:/codebase");

詳情：

使用以下JGit版本 4.8.0.201706111038-R

還與4.4.x.xxxxx版本太多

Answer 1

隨着這一變化的嘗試：https://git.eclipse.org/r/#/c/46261/，即我們在二月合併2017年，JGit應該能夠遵循HTTP 301狀態碼（永久移動）。

但是，CloneCommand似乎還沒有工作。我可以驗證你的代碼片段拋出TransportException。

相應的錯誤報告可以在這裏找到：

https://bugs.eclipse.org/bugs/show_bug.cgi?id=465167 https://bugs.eclipse.org/bugs/show_bug.cgi?id=474094

我已經加入到指向這個職位的錯誤報告的註釋。

更新2017年8月18日：的bug是固定的，並會在JGit 4.9
