Error when launching debug client

[EccentricVamp]

I'm trying to use Architectury Loom for a 1.19.2 Forge mod.

I downloaded the Forge template from Architectury Templates.

I changed the following values in gradle.properties

-minecraft_version=1.18.1
+minecraft_version=1.19.2
...
-forge_version = 1.18.1-40.1.0
+forge_version = 1.19.2-43.1.1

I ran the Gradle "build" and "vscode" tasks.

When I launch the "Minecraft Client" debugger, I get the following error

[16:41:27] [main/INFO] (Launcher) ModLauncher running: args [--launchTarget, forgeclientuserdev, --version, MOD_DEV, --assetIndex, 1.19.2-1.19, --assetsDir, C:\Users\Eccen\.gradle\caches\fabric-loom\assets, --gameDir, ., --fml.forgeVersion, 43.1.1, --fml.mcVersion, 1.19.2, --fml.forgeGroup, net.minecraftforge, --fml.mcpVersion, 20220805.130853, -mixin.config, examplemod.mixins.json]

Have you considered downloading the 1.19.2 template directly

[EccentricVamp]

Oops. I didn't scroll down enough to see it. I'll try that.

Where there big changes the Architectury Loom Forge template between 1.18.2 and 1.19.2?

[EccentricVamp]

The 1.19.2 template fails to build due to several errors.

I fixed the errors in the template

// src/main/java/com/example/examplemod/ExampleMod.java
// Line 6
-import net.minecraftforge.event.world.ExplosionEvent;
+import net.minecraftforge.event.level.ExplosionEvent;
...
// Line 44
-        LOGGER.info("Look, I found a {}!", Items.DIAMOND.getRegistryName());
+        LOGGER.info("Look, I found a {}!", ForgeRegistries.ITEMS.getKey(Items.DIAMOND));
...
// Line 55
-        LOGGER.info("Kaboom! Something just blew up in {}!", event.getWorld());
+        LOGGER.info("Kaboom! Something just blew up in {}!", event.getLevel());

After fixing the errors in the template, I reran the "build" and "vscode" Gradle tasks and got the same exact error

I've also tried

• Deleting the .gradle folder in the template
• Deleting the .gradle folder for my account
• Running the "clean" Gradle task
• Running gradlew --refresh-dependencies
• Deleting .vscode/launch.json

[EccentricVamp]

I don't think this was supposed to be fixed (I didn't see it in the changelog), but I'm still getting the error in Architectury Loom 1.0.302

[qyl27]

same problem here, my project is update from 1.18.2 and architectury loom 0.12.0-snapshot.

[EccentricVamp]

[moving new error to a separate issue]

[EccentricVamp]

Looks like several other people in Discord have the same issue

Cannot launch Forge client or server through run configurations

keep getting Module fmlloader reads another module named fmlloader

anyone know wtf is going on here?

All forge related tasks wont run only for me

[SolidBlock-cn]

Same problem for me. He happens for 0.12.0 and 1.0.

[SolidBlock-cn]

I've found a temporary fix for Module fmlloader reads another module named fmlloader. That's to exclude Forge in the build.gradle, such as:

modImplementation("pers.solid.mod:reasonable-sorting-forge:${project.reasonable_sorting_version}-mc${reasonable_sorting_mc_version}") {
    exclude group: "net.minecraftforge"
}

[EccentricVamp]

I tried the temporary fix. Unfortunately, it did not work for me.

Having this issue as well (Discord link):

Did anyone find a fix?
