Recompile mod with newer version of Java?

[JMAS]

I have a mod compiled with JDK 1.6 that I attempted to recompile with Java 1.8,  i.e. want to update a 1.7.10 mod and play it in 1.14.4.  I have the source code.  Working on Windows 10 with IntelliJ 2019.3 Build #IC-193.5233.102, Forge MDK-1.14.4-28.1.98-mdk. 

When testing updated mod, runClient, got "Caused by: java.io.IOException: Server returned HTTP response code: 400 for URL: http://myurl.me/"  

 

Any pointers in resolving this issue/updating the mod are greatly appreciated.

It would help if you provided the full debug.log

[JMAS]

I actually pulled all of my source (.java) files and ran the runClient with just the gradle files and received the same error message.    Minecraft loads.  No error message is generated in the logs subfolder of .Minecraft. 

 

The gradle files are: gradlew, build.gradle, gradle.properties, and gradlew.bat, with the folders: build, gradle, run and src. 

The error message listed in the opening post is within IntelliJ.

There should be a debug.log in run/logs

[JMAS]

There is this:

Comment out updateJSONURL in mods.toml, or replace the URL with a functioning one

[JMAS]

Thank you for your quick and direct response.

 

After making the changes directed, (commenting out), I now receive the following error:

Execution failed for task ':runClient'.
> Process 'command 'C:\Program Files\Java\jdk1.8.0_231\bin\java.exe'' finished with non-zero exit value 1 

 

Minecraft no longer loads.

No new debug.log was generated in run/logs.

?

more data included

[JMAS]

I continued poking around this morning, removing the 'comment out' and instead replacing the URL with a more complete version (updateJSONURL="https://www.myurl.me/") which threw this error:

 

Caused by: java.security.cert.CertificateException: No subject alternative DNS name matching www.myurl.me found.

Minecraft did load, but with the above error.

Mods.toml is created by Forge, yes?  Is myurl.me listed merely as an example?  Sorry if this is a stupid question, I've been learning Java for about 12 minutes now, so I'm a little short on experience.

 

I guess this resolves the first part of my issue, as runClient succeeds despite the errors.  Thank you for that.  Still hopeful for some wisdom or direction on attempting to recompile the mod from JDK 1.6 up to Java 1.8.  Perhaps a tutorial, video or some other instructional to succeed in this epic task?

Many thanks,

M

Thank you diesieben07.  

Go ahead and close this ticket.  I will continue learning about IntelliJ and the proper way to structure mods.  ?
