[root@test bin]# sh syncsvn.sh 
2014-12-23 14:22:52 begin repo 1
svn: OPTIONS of 'http://192.168.2.201/repos/v1.4': 200 OK (http://192.168.2.201)

svn: OPTIONS of 'http://192.168.2.201/repos/v1.4': 200 OK (http://192.168.2.201)
Some error occers: 
The command is /usr/bin/svn --non-interactive --username zhuchuan --password 123456 --no-auth-cache log -r 0:HEAD -v --xml http://192.168.2.201/repos/v1.4
the svn logs is <?xml version="1.0"?>

<log>

请问导致这个错误的原因是什么？

禅道里我的配置如下：

$config->svn = new stdClass();
$config->svn->encodings = 'utf-8, gbk';
$config->svn->client = '/usr/bin/svn';

$i = 1;
$config->svn->repos[$i]['path'] = 'http://192.168.2.201/repo
s/v1.4';
$config->svn->repos[$i]['username'] = 'zhuchuan';
$config->svn->repos[$i]['password'] = '123456';

/*
$i ++;
$config->svn->repos[$i]['path'] = '';
$config->svn->repos[$i]['username'] = '';
$config->svn->repos[$i]['password'] = '';
*/
