Drone Community:
I thought I would ask it here. It saves me from spending work doing it if it is already done. You know, “all that don’t reinvent the wheel stuff”. 
Has anyone developed a Semantic-Release drone plugin that I could use in my drone workflow?
If not, I was going to create one and contribute it back.
Thanks in Advance.
Cheers!
Hi, SGTGunner!
I need this plugin and have planned to implement it in October. It would be nice to use your implementation or to be involved in it. Let me know if I may help you.
Best regards,
Denis.
Hi Denis,
I am always looking for folks to collaborate with. Many hands make light work.
I have not created the drone plugin template yet. I will be doing that this week. I will send you a PM, with details and we can go from there.
Cheers,
SGTGunner
Hello, SGTGunner!
Is there any progress on semantic-release plugin?
Best regards,
Denis.
Perfect timing. I am nearly finished with it.
Thought, I have hit an issues and I will post here what the problem is:
I have the script.sh which looks like this:
#!/bin/sh
GH_TOKEN=${GITHUBTOKEN} npx semantic-release --branch ${PLUGIN_BRANCH} --no-ci
and within the .drome.yml it is called and looks like this:
semantic_release:
image: sgtgunner/drone-semantic-release:1.0.0
secrets: [ githubtoken ]
branch: feature/drone-semantic-release
when:
event:
- push
- pull-request
However, when I start the pipeline, I get the following error, where both variables are not being passed in.
And this is at the start of the image being called.
sh: missing ] 0s

Any assistance would be greatly appreciated!

Thinking about this more, would the branch: having something to do with it given it is passing a special character?
Update: When I tested it locally it did not have a problem and worked correctly passing in the -e variables.
Hi, not sure what is the problem here, although if you suspect it is the special character from “branch” you could try wrapping it with single quotes, i.e.: branch: 'feature/drone-semantic-release'
That said, drone injects into every build step a list of environment variables, including a DRONE_BRANCH, which includes your current branch, on ‘push’ events, at least, not sure about ‘pull-request’… in this case, I think it holds the branch your PR is pointing to!
Not sure if this is the most up-to-date list, but works for 0.8: http://docs.drone.io/environment-reference/
Thank you for your assistance. I did try using single quotes around branch: And I still got the same error.
You could also run a command like “env” inside your script to be sure that the arguments are being passed down correctly. And maybe also start the shell in debug mode (set -x) so it prints the “npx” command.
I like to add a “debug:” parameter to my plugins to print stuff like that, so it’s easy to find errors.
I have private repos on github. Mostly backends and frontends for web apps, they’re not npm libraries.
Here’s a drone plugin using semantic release for automating github releases.
