使用svnkit api，純java操作svn，實現svn提交，更新等操作（修正版）

此篇是在上一篇基礎上修改了bug。

文章主題是svnkit的api操作。所以涉及到其它類的，可以忽略。svnkit有兩套api，high level和low level 。high level是操作工作拷貝即working copy的。

我這兒用的就是high level。

checkWorkCopy方法裡面，先檢查當前指定的路徑是否是一個working copy。如果是，執行update操作；

如果不是的話，分兩種情況：

1.  svn上已經有以此project命名的項目，可能svn上有了，但working copy被刪了什麼的。就將該project  checkout下來；

2.  svn上沒有該project。此時checkout一個空的東西。SVNDepth.EMPTY，只是讓我們的路徑成為一個working copy，路徑下出現一個.svn目錄，svn上面的檔案不會被checkout下來。因為我們的svn上可能項目很多。如果把整個上級目錄checkout下來會很慢也浪費硬碟空間。

用 svnkit 執行commit操作，概況來說，流程如下：

1.  保證本地path是一個working copy。 即checkWorkCopy方法

2.  woking copy可能發生添加，更新，刪除等變化操作

3.  檢查working copy裡面的檔案是否under version control。即checkVersiondDirectory方法

4.  執行commit操作
