Trying a fresh install - minecraft bedrock won't start

I was having issues with upgrading my instance to the current version so decided to try a clean install. (I used the automated install)

I went through the standard setup, created a new minecraft bedrock instance and started it. Then I manage the instance, and hit update. After update I hit start, but then it gets strange. It essentially just goes into an unusable/unchangeable state without stopping the full instance. On the status page, it just shows 0's and the graphs across the page with no controls at all. The console screen stays completely blank.

When checking the logs, I find this error:

[Minecraft:admin Error] : Process configuration failed. Target jar file has not been specified or could not be automatically detected.

What changed such that the jar fine can't be detected? In the config, it's still set to autodetect.

Thanks!

Can you try:

  • Changing the server type to 'official'
  • Letting it install/update
  • Changing the server jar to the minecraft_server.jar
  • Changing the server type back to 'Bedrock'

Hi Mike,

When I change to official, change the jar etc, it fires up and works as expected.

Changing it back to Bedrock has the previously mentioned issues whether manually selecting the minecraft_server.jar or autoselect

So it's definitely Bedrock related, but I'm at a loss for why.

I'll have to take a look at this on Monday.

Thanks Mike. If it's helpful, I restored an old snapshot and found the same behavior in 2.0..6.8, so it's not just the current version.

Run

ampinstmgr --nocache upgrade INSTANCENAME

Where INSTANCENAME is the name of the Minecraft instance.

Mike, thank you!

That was the issue. I was able to make both the new test install and the upgraded version of my server work by doing this. Why wouldn't the new one be upgraded by default? Did I miss something?

Thanks again!

Previous thread deleted with more detail Just so I understand what I'm supposed to be doing here.

In console I am typing: ampinstmgr --nocache upgrade Minecraft01

I still get the following error when starting my instance

Could not complete action.

Process configuration failed. Target jar file has not been specified or could not be automatically detected.

Am I correct in that I need to run: ampinstmgr --nocache upgrade Minecraft01 from the console?
