- Could you update this config and its scripts to support JAVA 21 as starting from MC 1.20.5 it started using JAVA 21.

- Find away to replace server jars crons since their website is no longer contains MC repos

 

Thx

What's New in Version 2.4.0  

• [Added] Support for Java 21 (required as of Minecraft 1.20.5)

I just updated to the latest tcadmin as well as updated this. I cant run any of the newer versions that require Java 21. Just says StartError. Older versions are fine. Any ideas?

Edit: What fixed my issue is going to More on the server page and then doing Download or update Adoptium on your server.

Been having this issue for a bit, and not quite sure what's causing it or why it's only an issue on some modpack's being installed through the Panel.

Trying to install any version of certain curseforge modpacks yields this error despite what version I choose, or how I go about installing. It will typically download the mods, extract them and but hang when it tries to download the modloader/forge and error out at 4/5.

Any idea what might be causing this or any steps I can take to mitigate/resolve these issues?

[Dennis]

Some modpacks have the wrong information in the CurseForge API, and that will result in a 404 error when trying to download the modpack installer. Unfortunately, we can't really do anything about that at the moment.

I can't download Spigot because it can't find anything under this link
Windows File or URL: https://serverjars.com/api/fetchJar/servers/spigot spigot.jar

[Dennis]

ServerJars has unfortunately shut down. I'm looking for another API that can replace it.

What's New in Version 2.5.0  

• [Changed] The script that detects Java version has been replaced
  • Now performs three checks and determines the highest possible Java version
  • In some cases, this will be a bit slower - but the Java version is cached for that specific jar inside TCAFolder/Temp/MinecraftSHA256 and will be used when same jar is started. This is done across the entire server. Jars are matched against SHA256.
  • Old script is still available in case you experience issues
• [Added] Option to use modloader args (eg. @libraries\net\neoforged\neoforge\20.4.237\win_args.txt) in the commandline instead of jars. Requires version 2.0.192.9 or later
• [Fixed] Image links for some mods/updates

After importing/updating this, remember to click "Update existing services" in the game settings.

What's New in Version 2.5.1  

• [Fixed] In some cases, detecting the correct Java version would fail with "Cannot add the same member twice to a SerializationInfo object" when starting the server with a modloader.

After importing/updating this, remember to click "Update existing services" in the game settings.

Whats the use of supporting JAVA 22 on this config as long as latest MC version 1.21.4 is compatible with JAVA 21 ??

Some mods/plugins are starting to require Java 22.

 

e.g.

Something is definitely happening that shouldn't be happening. Does it happen on a new service as well?

Name: Install FTB Skies 2
Error: 3/8 - No mods available in the pack

Log Details
1/8 - Getting information about the modpack ID 1294237 version 6718199...
1/8 - Serverpack ID: 6718205
1/8 - Serverpack information received

3/8 - Extraction complete
3/8 - No mods available in the pack
3/8 - No mods available in the pack

Extracts to a temp directory, and FTB modpacks install an EXE that needs to be run to create the mods/configs/scripts for their packs. So after extract, need to run the EXE (can do from cmd-line). Thus causing the issue of being unable to install these. What would you say we do?
