Description

I am trying to append content to a sftp file. but vfs seems not supports that.

 

My test code: 

FileObject file = fsManager.resolveFile("sftp://root:xxx@192.168.1.1:22/sftpappend.txt" );
if (!file.exists()) {
    file.createFile();
}

FileContent content = file.getContent();
OutputStream outputStream = content.getOutputStream(true);

 

Error info :

org.apache.commons.vfs2.FileSystemException: The file type does not support append mode.

at org.apache.commons.vfs2.provider.AbstractFileObject.getOutputStream(AbstractFileObject.java:1180)
at org.apache.commons.vfs2.provider.DefaultFileContent.getOutputStream(DefaultFileContent.java:413)

I checked the source code. seems its easy to support APPEND option in sftp. Why commons-vfs doesn't do that?
