DevStack (./stack.sh) can not found test-requirement.txt dir

[Brin Zhang]

When I deploy the Master DevStack of manila ui, that report an error.

++/opt/stack/manila-ui/devstack/plugin.sh:install_manila_ui:8 mv /opt/stack/manila-ui/test-requirements.txt /opt/stack/manila-ui/_test-requirements.txt
mv: cannot stat ‘/opt/stack/manila-ui/test-requirements.txt’: No such file or directory
+/opt/stack/manila-ui/devstack/plugin.sh:install_manila_ui:1 exit_trap
+./stack.sh:exit_trap:531 local r=1
++./stack.sh:exit_trap:532 jobs -p

+./stack.sh:exit_trap:548 [[ 1 -ne 0 ]]
+./stack.sh:exit_trap:549 echo 'Error on exit'
Error on exit

This is issue result by follow function:

function install_manila_ui {
    # NOTE(vponomaryov): workaround for devstack bug: 1540328
    # where devstack install 'test-requirements' but should not do it
    # for manila-ui project as it installs Horizon from url.
    # Remove following two 'mv' commands when mentioned bug is fixed.
    mv $MANILA_UI_DIR/test-requirements.txt $MANILA_UI_DIR/_test-requirements.txt

    setup_develop ${MANILA_UI_DIR}

    mv $MANILA_UI_DIR/_test-requirements.txt $MANILA_UI_DIR/test-requirements.txt
}

There is an issue, when you deploy the DevStack failed in first time, and then retry, there will raise an exception with "mv $MANILA_UI_DIR/_test-requirements.txt $MANILA_UI_DIR/test-requirements.txt", beacuse the _test_requirements.txt is not exist, see `links`_.

Beacuse of manila-ui does not has the test-requirements.txt, so this will raise an exception, once the ./stack.sh run again.

The devstack plugin belongs to the manila project, not to devstack.

Hey Brin, can you share information about your deploy? Please share the local.conf file and also let me know about the distro in which you are running Devstack. Thanks!

hey, Brin any chance you can send us the local.cof and the distro your running dev stack on?
