When i have "MySQL JDBC" on the server it crashes during boot with this error.
I use MySQL JDBC for bluemap
Every time i reboot the server the mod at the end of the first line changes, in this example its "waystones"

Exception in thread "main" java.lang.module.ResolutionException: Modules grieflogger and mysql_jdbc export package com.mysql.cj.jdbc.result to module waystones at java.base/java.lang.module.Resolver.resolveFail(Resolver.java:901) at java.base/java.lang.module.Resolver.failTwoSuppliers(Resolver.java:815) at java.base/java.lang.module.Resolver.checkExportSuppliers(Resolver.java:736) at java.base/java.lang.module.Resolver.finish(Resolver.java:380) at java.base/java.lang.module.Configuration.<init>(Configuration.java:140) at java.base/java.lang.module.Configuration.resolveAndBind(Configuration.java:494) at MC-BOOTSTRAP/[email protected]/cpw.mods.modlauncher.ModuleLayerHandler.buildLayer(ModuleLayerHandler.java:75) at MC-BOOTSTRAP/[email protected]/cpw.mods.modlauncher.TransformationServicesHandler.buildTransformingClassLoader(TransformationServicesHandler.java:60) at MC-BOOTSTRAP/[email protected]/cpw.mods.modlauncher.Launcher.run(Launcher.java:106) at MC-BOOTSTRAP/[email protected]/cpw.mods.modlauncher.Launcher.main(Launcher.java:78) at MC-BOOTSTRAP/[email protected]/cpw.mods.modlauncher.BootstrapLaunchConsumer.accept(BootstrapLaunchConsumer.java:26) at MC-BOOTSTRAP/[email protected]/cpw.mods.modlauncher.BootstrapLaunchConsumer.accept(BootstrapLaunchConsumer.java:23) at [email protected]/cpw.mods.bootstraplauncher.BootstrapLauncher.main(BootstrapLauncher.java:141)

GriefLogger comes with the MySQL JDBC by default. So there is no need for a separate MySQL JDBC mod.

so i need to use an alternative sql thing for blue map, i spose thats easy enough. thanks for the info :)

I think if you remove the MySQL JDBC mod, blue map will use the one that comes with GriefLogger, cuz its just a clone of the MySQL JDBC, just like the MySQL JDBC mod.

bluemap spit out errors saying it couldnt locate sql when i tried that before.

You can set a "driver-jar" path in the bluemap config, it recommends "mariadb-java-client" which is what i did before reading your reply.
Setting the "driver-jar" path to mods/grieflogger-1.1.2-forge.jar also seems to work! thanks again :)

Awesome, thank you for letting me know!
