SFTP authorization fail during publishing via sftp.
---------------------------------------------------
Key: IVY-660
URL: https://issues.apache.org/jira/browse/IVY-660
Project: Ivy
Issue Type: Bug
Components: Core
Affects Versions: 2.0.0-beta-1
Environment: Developer: Windows XP, jdk1.6.0_02, ant-1.7.0, jsch-0.1.36
SFTP Server: FreeBSD-6.2-RELEASE.
Reporter: Alexey Kiselev
Priority: Minor
Fix For: 2.0.0-beta-1
PROBLEM:
We defined two resolvers in a settings file:
<resolvers>
<sftp name="remote1">
<ivy pattern="sftp://user:[EMAIL
PROTECTED]:12345/repository/[module]/[module]-[revision].xml"/>
<artifact pattern="sftp://user:[EMAIL
PROTECTED]:12345/repository/[module]/[artifact]-[revision].[ext]"/>
</sftp>
<sftp name="remote2" host="host" port="12345" user="user"
userPassword="password">
<ivy
pattern="repository/[module]/[module]-[revision].xml"/>
<artifact
pattern="repository/[module]/[artifact]-[revision].[ext]"/>
</sftp>
</resolvers>
Then we tried to publish our artifacts
<ivy:publish resolver="remote1" pubrevision="1.2.3.4" overwrite="true"
artifactspattern="${basedir}/files/[artifact].[ext]" />
or
<ivy:publish resolver="remote2" pubrevision="1.2.3.4" overwrite="true"
artifactspattern="${basedir}/files/[artifact].[ext]" />
As a result we had received java.io.IOException with message "Auth fail".
SOLUTION:
Our solution is to implement interface com.jcraft.jsch.UIKeyboardInteractive in
class CfUserInfo in file SshCache.java. Patch had been attached below.
