The code I wrote should be fine, at least Idea did not report any errors, and there were no errors before adding this dependency. From the error message, the main error is java. lang.

The Minecraft version must agree with the Forge version to get a valid artifact

minecraft_version=1.20.1

The Minecraft version range can use any release version of Minecraft as bounds.

Snapshots, pre-releases, and release candidates are not guaranteed to sort properly

as they do not follow standard versioning conventions.

minecraft_version_range=[1.20.1,1.21)

The Forge version must agree with the Minecraft version to get a valid artifact

forge_version=47.3.29

The Forge version range can use any version of Forge as bounds or match the loader version range

forge_version_range=[47,)

The loader version range can only use the major version of Forge/FML as bounds

mapping_channel=official

The mapping version to query from the mapping channel.

This must match the format required by the mapping channel.

mapping_version=1.20.1

The unique mod identifier for the mod. Must be lowercase in English locale. Must fit the regex [a-z][a-z0-9_]{1,63}

Must match the String constant located in the main mod class annotated with @mod.

mod_id=mymod

The human-readable display name for the mod.

mod_name=mymod

The license of the mod. Review your options at https://choosealicense.com/. All Rights Reserved is the default.

mod_license=All Rights Reserved

The mod version. See https://semver.org/

mod_version=1.0-SNAPSHOT

The group ID for the mod. It is only important when publishing as an artifact to a Maven repository.

This should match the base package used for the mod sources.

See https://maven.apache.org/guides/mini/guide-naming-conventions.html

mod_group_id=mod

The authors of the mod. This is a simple text string that is used for display purposes in the mod list.

mod_authors=lemon_sjdk

The description of the mod. This is a simple multiline text string that is used for display purposes in the mod list.

mod_description=
mod.toml:# This is an example mods.toml file. It contains the data relating to the loading mods.

There are several mandatory fields (#mandatory), and many more that are optional (#optional).

The overall format is standard TOML format, v0.5.0.

Note that there are a couple of TOML lists in this file.

Find more information on toml format here: https://github.com/toml-lang/toml

The name of the mod loader type to load - for regular FML @mod mods it should be javafml

modLoader = "javafml" #mandatory

A version range to match for said mod loader - for regular FML @mod it will be the forge version

loaderVersion = "${loader_version_range}" #mandatory This is typically bumped every Minecraft version by Forge. See our download page for lists of versions.

The license for you mod. This is mandatory metadata and allows for easier comprehension of your redistributive properties.

Review your options at https://choosealicense.com/. All rights reserved is the default copyright stance, and is thus the default here.

license = "${mod_license}"

A URL to refer people to when problems occur with this mod

#issueTrackerURL="https://change.me.to.your.issue.tracker.example.invalid/" #optional

A list of mods - how many allowed here is determined by the individual mod loader

[[mods]] #mandatory

The modid of the mod

modId = "${mod_id}" #mandatory

The version number of the mod

version = "${mod_version}" #mandatory

A display name for the mod

displayName = "${mod_name}" #mandatory

A URL to query for updates for this mod. See the JSON update specification https://docs.minecraftforge.net/en/latest/misc/updatechecker/

#updateJSONURL="https://change.me.example.invalid/updates.json" #optional

A URL for the "homepage" for this mod, displayed in the mod UI

#displayURL="https://change.me.to.your.mods.homepage.example.invalid/" #optional

A file name (in the root of the mod JAR) containing a logo for display

#logoFile="lemon.png" #optional

A text field displayed in the mod UI

#credits="Thanks for this example mod goes to Java" #optional

A text field displayed in the mod UI

authors = "${mod_authors}" #optional

Display Test controls the display for your mod in the server connection screen

MATCH_VERSION means that your mod will cause a red X if the versions on client and server differ. This is the default behaviour and should be what you choose if you have server and client elements to your mod.

IGNORE_SERVER_VERSION means that your mod will not cause a red X if it's present on the server but not on the client. This is what you should use if you're a server only mod.

IGNORE_ALL_VERSION means that your mod will not cause a red X if it's present on the client or the server. This is a special case and should only be used if your mod has no server component.

NONE means that no display test is set on your mod. You need to do this yourself, see IExtensionPoint.DisplayTest for more information. You can define any scheme you wish with this value.

IMPORTANT NOTE: this is NOT an instruction as to which environments (CLIENT or DEDICATED SERVER) your mod loads on. Your mod should load (and maybe do nothing!) whereever it finds itself.

#displayTest="MATCH_VERSION" # MATCH_VERSION is the default if nothing is specified (#optional)

The description text for the mod (multi line!) (#mandatory)

description = '''${mod_description}'''

A dependency - use the . to indicate dependency for a specific modid. Dependencies are optional.

[[dependencies."${mod_id}"]] #optional

the modid of the dependency

modId = "forge" #mandatory

Does this dependency have to exist - if not, ordering below must be specified

mandatory = true #mandatory

The version range of the dependency

versionRange = "${forge_version_range}" #mandatory

An ordering relationship for the dependency - BEFORE or AFTER required if the dependency is not mandatory

BEFORE - This mod is loaded BEFORE the dependency

AFTER - This mod is loaded AFTER the dependency

ordering = "NONE"

Side this dependency is applied on - BOTH, CLIENT, or SERVER

side = "BOTH"# Here's another dependency
[[dependencies."${mod_id}"]]
modId = "minecraft"
mandatory = true

This version range declares a minimum of the current minecraft version up to but not including the next major version

versionRange = "${minecraft_version_range}"
ordering = "NONE"
side = "BOTH"
Main category：@mod("mymod")
public class Mymod {
public static final String MODID = "mymod";
public Mymod(FMLJavaModLoadingContext context) {
