I'm making a plugin that I will post on Bukkit soon, but I need help atm. While I was exporting and reloading my local server, I had a new error that I can't figure out. My first Yaml block "plugin" suddently causes errors. The console is telling me that it's expected to be "<document start>" and that it's a BlockMappingStart (l.7, c.1).

Here is my config: (open) Here is my config: (close)

As I understood, the error is happening while trying to load the "plugin.tag" string. Maybe the problem is a bad yaml spacing, but I didn't find where is the error as I don't remember that I changed the method .getPluginTag() or my config.

I hope someone can help me because I'll be late for my plugin release ! ^.^'
Thanks in advance for your future answers. Burn38.

 

@Burn38 I'm just guessing that your spaces are messed up (in config)

 

@MasterMatt5 Yes I know, but the strange thing is that I didn't find anything wrong (the given line + column by the log is l.7 (the first line without comments) and col.1 (the first char) it's the first line and it's sticked to the left side ). I also tried to check my YAML code on multiples YAML checkers website like www.yamllint.com, yaml-online-parser.appspot.com and no errors are found >.<'
I hope someone will find the error because I already double / triple checked the config and I didn't see anything (maybe because I'm blind ? )

 

@Burn38
It may just be the website, but in that yml it appears that on each empty line is a space, it could be that.

 

Ok, I just figured it out. I replaced all the spaces by other spaces manually and now it works. Idk why but it works now, thanks everybody for your help / suggestions
