Connection to Subversion repository http://svn.xxx.cn/Current failed: org.tmatesoft.svn.core.SVNAuthenticationException: svn: Authentication required for '<http://svn.xxx.cn:80>'
原因：据说是svnkit包的一个bug.
解决方案：
添加JVM系统参数-Dsvnkit.http.methods=Basic,Digest,NTLM
Properties properties = System.getProperties();
properties.setProperty("svnkit.http.methods", "Basic,Digest,NTLM");
org.tmatesoft.svn.core.SVNException: svn: Unable to create SVNRepository object for
原因：svn访问地址与调用的方法不一致
解决方案：svn://xx.xx.xx -- SVNRepositoryFactoryImpl.setup();
http://xx.xx.xx -- DAVRepositoryFactory.setup( );
mvn install:install-file -Dfile=E:\software\svnkit.jar -DgroupId=thirdlib -DartifactId=svnkit -Dversion=1.3.5 -Dpackaging=jar -DgeneratePom=true -DcreateChecksum=true
作用：将本地jar加入到maven2仓库。
maven1.0不含mvn命令，如需要将jar加入到本地的maven仓库，可以到仓库按其它包目录结构创建文件夹，并将本地jar拷贝到创建的目录下，在project.xml添加相应的依赖关系即可使用。
java.lang.IllegalArgumentException: Action 'com.xxx.jira.web.action.issue.CheckSvnCommitIssue' could not be instantiated. Class is invalid or static initializers have failed to run
原因：未将相应的jar包拷贝到主程序的lib目录下，在插件部分加了jar包，所以编译不会出错，但当运行时就会报如上错误。
解决方案：在主程序的project.xm也需要加相应的依赖。
java访问svn测试代码：
public class History { public static void main(String[] args) { Properties properties = System.getProperties(); properties.setProperty("svnkit.http.methods", "Basic,Digest,NTLM"); DAVRepositoryFactory.setup(); // SVNRepositoryFactoryImpl.setup(); String url = "http://svn.xxx.cn/current"; // String url = "svn://localhost"; String name = "username"; String password = "password"; long startRevision = 0; long endRevision = -1; // HEAD (the latest) revision SVNRepository repository = null; try { repository = SVNRepositoryFactory.create(SVNURL .parseURIEncoded(url)); } catch (SVNException e) { e.printStackTrace(); } ISVNAuthenticationManager authManager = SVNWCUtil .createDefaultAuthenticationManager(name, password); repository.setAuthenticationManager(authManager); final Collection logEntries = new ArrayList(); long start = System.currentTimeMillis(); try { repository.log(new String[] { "" }, startRevision, endRevision, true, true, new ISVNLogEntryHandler() { public void handleLogEntry(SVNLogEntry entry) { if (entry.getMessage().indexOf("QS-5762") != -1) { logEntries.add(entry); } } }); } catch (SVNException e) { e.printStackTrace(); } for (Iterator entries = logEntries.iterator(); entries.hasNext();) { SVNLogEntry logEntry = (SVNLogEntry) entries.next(); System.out.println("---------------------------------------------"); System.out.println("revision: " + logEntry.getRevision()); System.out.println("author: " + logEntry.getAuthor()); System.out.println("date: " + logEntry.getDate()); System.out.println("log message: " + logEntry.getMessage()); if (logEntry.getChangedPaths().size() > 0) { System.out.println(); System.out.println("changed paths:"); Set changedPathsSet = logEntry.getChangedPaths().keySet(); for (Iterator changedPaths = changedPathsSet.iterator(); changedPaths .hasNext();) { SVNLogEntryPath entryPath = (SVNLogEntryPath) logEntry .getChangedPaths().get(changedPaths.next()); System.out.println(" " + entryPath.getType() + " " + entryPath.getPath().substring( entryPath.getPath().lastIndexOf("/") + 1)); } } } }}
