Class Not Found Exception when I try to run my compiled mod

Posted January 3, 201411 yr

After spending a little while making my first Forge mod, I decided to test it out alongside other mods. I ran recompile.sh, followed by reobfuscate_srg.sh. I then put the advancedKinetics folder (advancedKinetics is the name of my mod) from reobf into a zip, as well as my assets. The mod zip can be found in the attachments. I added the zip to an FTB instance (Horizons), which crashed on launch. I then decided to add it to a fresh Forge instance, which still gave me the same type of crash. The log from that crash can be found here.

Check the zip file's construction. Make sure that it has the correct folder structure; the most common reason for this crash is that your mod wasn't zipped correctly.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

DO NOT PM ME WITH PROBLEMS. No help will be given.

Here is the zip. It's structured like so:

advancedKinetics.zip

advancedKinetics

blahblah.class

assets

advancedkinetics

textures

blocks

blahblah.png

items

you need to have it like this

advancedKinetics.zip

hexaguin

advancedKinetics

blahblah.class

assets

Eclipse Throwing "Could not create an instance of Tooling API" and "Could not run build action"

Hey fellas!

I've been trying for the past few months to fix this miserable, horrible, god awful, hair pulling, hopelessly relentless error I've been having with my imported Gradle projects that have worked fine for several years until I made the mistake of installing Java-17 and Java-21. Basically, I think I know exactly what is causing the error.

Gradle for Minecraft Forge 1.12.2 uses Gradle Distribution 4.9, which is literally like ancient technology, so it requires Java-8. But for some incredibly stupid reason that is just completely beyond me, the moment I installed Java-17, it became utterly and entirely impossible to convince eclipse to just use Java-8. I've tried everything: I've yelled at it, I've spoken softly to it, I've even tried actually fixing, but nothing I have done has seemed to work. Literally, every single time I try to fix this problem, a new one pops up. I am sick and tired of having to navigate this LABYRINTH of errors. I think I know how Hercules must have felt trying to slay the hydra at this point. I add launch options to fix it, and now it's generating, "Could not run build action." I try to force eclipse to use a different java version, and it says, "Eclipse requires java blah blah blah." What am I supposed to do at this point? The only way I am able to assemble my 1.12.2 mods is to use Command Prompt and forcibly set the JRE for the gradlew batch file to Java-8. BUT THEM I'M STUCK WITH RUNNING IT ON THE BATCH FILE. I already have so many windows pulled up when I'm modding Minecraft that when I assemble my mod istg I can actually hear my computer start shaking. Trying to reach google through all my windows is like trying to uncover ancient mayan ruins! The last thing I need is EVEN MORE WINDOWS.

Now, before you ask any questions, I'm going to try to cover them here, so get ready:

Have you tried praying?
Yes, that's like the first thing I tried.

Did you try putting it in rice?
...

Did you try changing your Gradle Distribution version?
Yes, it needs gradle 4.9, otherwise I get another error that says something like "Needs gradle 4.9.x or below".

Can you please provide the errors that were generated?
Sure, here's the error that was first generated when I noticed this problem:
org.gradle.tooling.GradleConnectionException: Could not create an instance of Tooling API implementation using the specified Gradle distribution 'https://services.gradle.org/distributions/gradle-4.9-bin.zip'.

What launch options did you add to the eclipse jre?
These ones: --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED
I put them at the very end of my eclipse.ini file, btw.

Have you tried uninstalling your later java versions?
Yes, but it's no use, eclipse will just magically pull up another more updated java version like a magician pulling a bunny out of a hat.

Have you tried just using IntelliJ?
I will never join the dark side!

You know IntelliJ actually provides some better maneuverability than ecli-
YOUR TRICKS AREN'T GOING TO WORK ON ME!

Have you tried just simply deleting the java that eclipse will use?
Yes, but when I do eclipse blows up and melts down like reactor number 4. (I will not be trying that again, btw.)

What did you do to the gradlew batch file to make it work that you can't do with eclipse?
VERY EXCELLENT QUESTION!
I just added set "JAVA_HOME=C:\Users\[MY USERNAME]\JDK8\jre" to the very beginning of the batch file.
And yes, I know this JRE is installed in a very strange spot, and I also know that it says "JDK" before opening into a folder called "jre". I installed this folder when I was like, six; c'mon, cut me a little slack.

Could you provide the path to the java environment that eclipse is currently using?
Absolutely: C:/Users/[MY USERNAME]/.p2/pool/plugins/org.eclipse.justj.openjdk.hotspot.jre.full.win32.x86_64_23.0.1.v20241024-1700/jre/bin

Have you tried changing your java home variables on your system and what not?
Yes, but to no avail; eclipse will just continue using the JRE supplied to it in it's ini file.

Have you tried just making a new project and exporting everything over there to see if it works?
I tried making a new project, but I could instantly tell it wasn't going to work just based on that fact that I immediately get the "Could not create an instance of Tooling API" error.

Have you tried downgrading eclipse?
No, and I'm honestly pretty scared to do that because I don't want to have to deal with another meltdown again. If there are no other ways to get eclipse to use a lower java version, then this is probably what I'll end up doing if I don't die from frustration before I get there.

Have you tried uninstalling some eclipse plugins and downgrading the java that eclipse requires in the ini file?
No, and I'm again afraid of doing it for the exact same reasons as stated above.

What is the required java version in the eclipse ini file?
Java-11

I'm hoping somebody here knows a way around this problem that allows me to use eclipse to build my forge 1.12.2 gradle projects. Actually, strangely, I just though of the fact that it's JUST my 1.12.2 projects that are failing. That's interesting because I do in fact have a GT New Horizons 1.7.10 mod that NEVERMIND, I just checked and apparently those crazy insane people down workin' on the GTNH mod pack managed to used gradle distribution 8.13 in their template project. I guess they're just a bunch of gigachads that literally built their mod pack from the ground up. Maybe I might end up just doing what they did and make my own forge gradle mod template, but that would REALLY suck having to do that for any gradle version that doesn't like java 21. If somebody knows how to get eclipse to just use an earlier version of java, please for the love of all that is holy, help me out! In the meantime, I guess I got no other good choice but to use the command line.

I'm hoping this post reaches somebody that can help.
