The issue is likely that the bifromq-auth-plugin-1.0.0.zip archive is
missing the line "Plugin-Version: 1.0.0" in the file
classes/META-INF/MANIFEST.MF. Please check it. If it's missing, you can unzip
the file, add that line manually, and then try starting it again.
Also, please check the content in Step 3 :
```
Plugin-Class: ${plugin.class}
Plugin-Id: ${plugin.id}
Plugin-Version: ${project.parent.version}
```
