Short command list of what is now needed to setup forge and MDK

Primer Forge Gradle Commands for 1.13 and later.md

If a command breaks, use --no-daemon as the ForgeGradle currently doesn't uses it

Setup MDK (For Modders who want to create a mod)

• Download the MDK from forge (Forge Test Version for 1.13)
• ./gradlew eclipse
• ./gradlew genEclipseRuns to generate the launch configuration
• (./gradlew genIntellijRuns for IntelliJ users)
• run this two times so the libs get properly linked
• Importing into IDE has not changed

Running client

• ./gradlew runClient

Running Server

• ./gradlew runServer

Setup FORGE (for those wishing to work on forge directly)

• Clone the Forge Repo
• ./gradlew setup
• If it crashes try running it again, as this sometimes helps
• ./gradlew eclipse
• this generates the eclipse files
• you can then import the projects inside the "projects" folder in an existing workspace
• ./gradlew genIntellijRuns for IntelliJ users
• this creates the IntelliJ files
• Setup IntelliJ

For Generating the Patches

• ./gradlew :forge:genPatches

Running client

Vanilla client:

• ./gradlew clean:runclient

Forge Client:

• ./gradlew forge:runclient

Running Server

Forge Server:

• ./gradlew forge:runserver

@HenryLoenwind For Initial eclipse setup I just ran gradlew eclipse 3 times (to make sure the last one finsihes in 5seconds so everything is done) and then imported the folder as existing java project (can also be imported as a gradle project).
For updating simple use:

• gradlew clean
• gradlew eclipse --refresh-dependencies --no-daemon (again 2 times so the libs get linked)

for IntelliJ users, it's probably worth noting that you'll want to use the .idea (directory based) configuration rather than the *.ipr (file based) configuration.

When I perform the setup from the first part (importing into IntelliJ), it doesn't work, showing a missing dependency of net.minecraftforge:forge:1.13.2-25.0.10_mapped_snapshot_20180921-1.13. The gradle sync results also report java.lang.IllegalStateException: ProjectScopeServices has been closed.

Any idea what to do? I've been trying to get the MDK working literally all day long and this is the furthest I've gotten without something breaking.

It looks like clean:runclient has been renamed to clean_client and forge:runclient has been renamed to forge_client. Furthermore, forge_client fails for me, saying Error: Could not find or load main class net.minecraftforge.userdev.LaunchTesting. clean_client works fine.

Is it possible to run the mod directly in eclipse instead of the commandline?

Is developing mods without an IDE no longer supported? eg: editing source in vim and then building with gradle commands?

I used to use gradle setupDecompWorkspace and it would set up everything I needed including decompiled source to the build\tmp directory. Does gradle eclipse replace that?

thank you!!!! gradlew runClient helped me run Minecraft Forge!!!
look...

for creating mods I did exactly what you said and eclipse still cant find the net libraries

I REALLY need a way to figure this out, im tired and haven't gotten even remotely close to being able to make the simplest mod because of this damn way they have everything set up. Like why cant it be like visual studio where you create the project and your good to go

I recommend the forge discord if you have problems.
