Try to copy a file from local to sftp server, if the sftp target directory can't write by the sftp user, it throw a exception as below. ``` Caused by: org.apache.commons.vfs2.FileSystemException: Could not write to "sftp://sftpuser:***@localhost/noperms/test.dat.tmp";. at org.apache.commons.vfs2.provider.AbstractFileObject.getOutputStream(AbstractFileObject.java:1270) at org.apache.commons.vfs2.provider.DefaultFileContent.buildOutputStream(DefaultFileContent.java:540) at org.apache.commons.vfs2.provider.DefaultFileContent.getOutputStream(DefaultFileContent.java:406) at org.apache.commons.vfs2.provider.DefaultFileContent.getOutputStream(DefaultFileContent.java:394) at org.apache.commons.vfs2.provider.DefaultFileContent.write(DefaultFileContent.java:815) at org.apache.commons.vfs2.provider.DefaultFileContent.write(DefaultFileContent.java:833) at org.apache.commons.vfs2.FileUtil.copyContent(FileUtil.java:37) at org.apache.commons.vfs2.provider.AbstractFileObject.copyFrom(AbstractFileObject.java:297) ... 29 common frames omitted Caused by: com.jcraft.jsch.SftpException: Permission denied at com.jcraft.jsch.ChannelSftp.throwStatusError(ChannelSftp.java:2873) at com.jcraft.jsch.ChannelSftp.put(ChannelSftp.java:768) at com.jcraft.jsch.ChannelSftp.put(ChannelSftp.java:709) at com.jcraft.jsch.ChannelSftp.put(ChannelSftp.java:706) at org.apache.commons.vfs2.provider.sftp.SftpFileObject.doGetOutputStream(SftpFileObject.java:483) at org.apache.commons.vfs2.provider.AbstractFileObject.getOutputStream(AbstractFileObject.java:1266) ... 36 common frames omitted ``` the exception is from the version 2.5.0. the retry times is more than 20, then the exception stack as below: ``` Caused by: org.apache.commons.vfs2.FileSystemException: Could not connect to SFTP server at "sftp://sftpuser:***@localhost/";. at org.apache.commons.vfs2.provider.sftp.SftpFileSystem.getChannel(SftpFileSystem.java:159) at org.apache.commons.vfs2.provider.sftp.SftpFileObject.statSelf(SftpFileObject.java:106) at org.apache.commons.vfs2.provider.sftp.SftpFileObject.doGetType(SftpFileObject.java:76) at org.apache.commons.vfs2.provider.AbstractFileObject.getType(AbstractFileObject.java:1368) ... 30 common frames omitted Caused by: com.jcraft.jsch.JSchException: channel is not opened. at com.jcraft.jsch.Channel.sendChannelOpen(Channel.java:768) at com.jcraft.jsch.Channel.connect(Channel.java:151) at org.apache.commons.vfs2.provider.sftp.SftpFileSystem.getChannel(SftpFileSystem.java:133) ... 33 common frames omitted ``` Although the sftp directory permission problem is fixed, the file cannot be copied to the sftp target directory, and the error stack still `channel is not opened`. The PR try to catch the exception on `SftpFileObject.doGetOutputStream`, if there is a exception on the method `channel.put`, use the `getAbstractFileSystem().putChannel(channel)` to return the channel to the pool. -- This is an automated message from the Apache Git Service.
