SSH / SCP tasks no longer working in Bamboo 6.0.2





      SCP and SSH tasks are not working in Bamboo 6.0.2.

      Steps to Reproduce

      1. Setup a plan with SCP task to copy some files from a local path to a remote path
      2. Run the plan

      Expected Results

      The SCP and SSH tasks are able to establish a connection, build succeeds.

      Actual Results

      The below exception is thrown in the build log with private key authentication:

      • Affects both password and private key authentication


      1. Stop Bamboo
      2. Download bamboo-scp-plugin-6.0.1.jar
      3. Go to <bamboo_install>/atlassian-bamboo/WEB-INF/atlassian-bundled-plugins/
      4. Move the old plugin, bamboo-scp-plugin-6.0.0.jar out of that directory into a non-Bamboo location (for simple backup purposes)
      5. Place the fixed plugin, bamboo-scp-plugin-6.0.1.jar, into that directory.
      6. Start Bamboo

      Alternate workaround:

      1. Disable the SCP / SSH task
      2. Add a script task the performs the equivalent functions on command-line. Example below which uses password authentication to recursively copy a local path to a remote path (password in the below example is substituted from a Bamboo Plan variable):
        sshpass -p ${bamboo.scp_password} scp -r local/path/ user@host:/remote/path
