正如我们所知，我们可以使用 Tortoise svn 等工具执行 svn 操作，如 check out 、提交、更新。
现在我正在尝试使用 ant 脚本执行 svn 操作，如 svn check out 、提交、更新(这样 svn 进程会容易得多)。
我正在尝试使用 svnkit sdk 给定如下:

我能够获得一些输出作为历史记录:
revision: 7
author: username
date: Wed Apr 23 15:47:58 2014
log message: testing
changed paths:
A /testCode/src
但是当我调用 SVNCommitInfo copyDir() 方法时出现以下错误:
org.tmatesoft.svn.core.SVNException: svn: E160013: '/testCode/!svn/bc/2/C:/svnCommitCode/src' path not found: 404 Not Found (http://svnUrl)
我同时提供源(我的本地系统目录路径)和目标路径(svn 目录路径)，我在这里做错了什么？ (意味着在 svn 上存在相同的“src”文件夹，我只想替换为当前本地目录。)
谁能在这方面指导我？
最佳答案
这个解决方案对我有用。
首先调用此方法getSVNClientManager 进行身份验证，它将返回clientManager，用于获取不同类型的svn 客户端实例以执行不同的 Activity 。
public SVNClientManager getSVNClientManager () throws IOException{
SVNURL url = SVNURL
.parseURIDecoded("<path to the base svn repository>");
SVNRepository repository = SVNRepositoryFactory.create(url, null);
ISVNOptions myOptions = SVNWCUtil.createDefaultOptions(true);
//provide svn username and password
//username = name used to connect to svn
//password = password used to connect to svn
ISVNAuthenticationManager myAuthManager = SVNWCUtil
.createDefaultAuthenticationManager("<username>", "<password>");
repository.setAuthenticationManager(myAuthManager);
//clientManager will be used to get different kind of svn clients instances to do different activities
//like update, commit, view diff etc.
SVNClientManager clientManager = SVNClientManager.newInstance(
myOptions, myAuthManager);
return clientManager ;
}
然后调用方法commitToSvn()
public void commitToSvn(SVNClientManager clientManager)
throws SVNException {
SVNCommitClient commitClient = clientManager.getCommitClient();
File fileToCheckin = new File("LocalDir/SampleFileFolder/SampleFile1");
boolean recursive = true;
SVNCommitInfo importInfo = commitClient
.doImport(
fileToCheckin ,
SVNURL.parseURIDecoded("<path at which we want to check-in the file>"),
"testing svn kit integration", recursive);
System.out.println(importInfo.getNewRevision());
}
同样我们可以调用checkout方法exportFromSvn()
public void exportFromSvn(SVNClientManager clientManager) throws SVNException {
SVNUpdateClient updateClient = clientManager.getUpdateClient();
SVNURL url = SVNURL.parseURIDecoded("<svn url to export from>");
//destination path
File dstPath = new File("LocalDirNew");
//the revision number which should be looked upon for the file path
SVNRevision pegRevision = SVNRevision.create(<right svn revision number>);
//the revision number which is required to be exported.
SVNRevision revision = SVNRevision.create(<right svn revision number>);
//if there is any special character for end of line (in the file) then it is required. For our use case, //it can be null, assuming there are no special characters. In this case the OS specific EoF style will //be assumed
String eolStyle = null;
//this would force the operation
boolean force = true;
//Till what extent under a directory, export is required, is determined by depth. INFINITY means the whole subtree of that directory will be exported
SVNDepth recursive = SVNDepth.INFINITY;
updateClient.doExport(url, dstPath, pegRevision, revision, eolStyle, force, recursive );
}
