Hello
So my traccar installation failed to start, and after some digging i found the wrapper log stuck in a loop printing

And after a while it spits out

Now, the changelog file in question ./schema/changelog-master.xml isn't locked at all and i've tried restarting the machine, and reinstalling traccar.
Since this is a dev machine, i don't really care about it and just want to know if it's possible to skip this changelog lock step and just get the server up, or is there some other way to fix this?
If it's a dev machine you can just re-create database to fix this problem. If you need to keep database, search on forum and GitHub. The problem has been discussed before and there were a few solutions available.
Did a little more digging, found the h2 databasechangelock table.
Guessing i should just delete this record right?
If you want to learn more about it you should read about Liquibase library, but I would recommend look for solution on forum and GitHub. As I said, it has been discussed several times before.
Deleted the entry, works now.. thanks.
Will checkout that liquibase library documentation if i get another convoluted problem.
mark this as closed.... :)
