The idea of this script is to update gh-pages branch with the generated docs. Without any options
|
||
|
|
the script will work in the following manner:
|
||
|
|
|
||
|
|
- if there's no gh-pages / target for docs module then the script ends
|
||
|
|
- for master branch the generated docs are copied to the root of gh-pages branch
|
||
|
|
- for any other branch (if that branch is whitelisted) a subfolder with branch name is created
|
||
|
|
and docs are copied there
|
||
|
|
- if the version switch is passed (-v) then a tag with (v) prefix will be retrieved and a folder
|
||
|
|
with that version number will be created in the gh-pages branch. WARNING! No whitelist verification will take place
|
||
|
|
- if the destination switch is passed (-d) then the script will check if the provided dir is a git repo and then will
|
||
|
|
switch to gh-pages of that repo and copy the generated docs to `docs/<project-name>/<version>`
|
||
|
|
- if the destination switch is passed (-d) then the script will check if the provided dir is a git repo and then will
|
||
|
|
switch to gh-pages of that repo and copy the generated docs to `docs/<project-name>/<version>`
|
||
|
|
|
||
|
|
USAGE:
|
||
|
|
|
||
|
|
You can use the following options:
|
||
|
|
|
||
|
|
-v|--version - the script will apply the whole procedure for a particular library version
|
||
|
|
-d|--destination - the root of destination folder where the docs should be copied. You have to use the full path.
|
||
|
|
E.g. point to spring-cloud-static folder. Can't be used with (-c)
|
||
|
|
-b|--build - will run the standard build process after checking out the branch
|
||
|
|
-c|--clone - will automatically clone the spring-cloud-static repo instead of providing the destination.
|
||
|
|
Obviously can't be used with (-d)
