====== Steps to Build and Run master-MC1.7.10 from source

These instructions assume you have cloned the repo, git clone git@github.com:MightyPirates/OpenComputers.git and are working from the master-MC1.7.10 branch, currently the default branch.

IDEA instructions

run `./gradlew setupDecompWorkspace`

run `./gradlew build`

run `./gradlew idea`

From IDEA, open the OpenComputers.ipr created from `./gradlew idea`

Open File->Project Structure (or press Shift+Control+Alt+S)

In the left pane select Modules

Depending on how you imported the project there may be mulitple top level modules. There should only be one. Keep only the one named OpenComputers which has three sub modules named `OpenComputers_api`, `OpenComputers_main`, and `OpenComputers_test`. Right click on the others and choose to delete them.

Set separate output paths for `OpenComputers_api` and `OpenComputers_main`. In the middle pane select `OpenComputers_api`, in the right pane select "Paths" and change the "Output path:" from ending in /main to end in /api

Set the scope of other minecraft mods in Dependencies "provided". This needs to be done for `OpenComputers_api` as well as `OpenComputers_main`. Select "Dependencies" in the right pane. A large list of dependencies are listed. All, by default due to importing the gradle properties, will default to "Compile". Set all of the following to "Provided"

- factorization-api
- ic2classic-api
- AgriCraft
- Gradle: appeng:RotaryCraft:api
- Gradle: appeng:appliedenergistics2
- Gradle: codechicken:EnderStorage
- Gradle: codechicken:WR-CBE
- Gradle: com.bluepowermod:BluePower
- Gradle: com.gregoriust.gregtech
- Gradle: igwmod:IGW-Mod-1.7.10
- Gradle: li.cil.tis3d:TIS-3D
- Gradle: mcp.mobius.waila
- Gradle: net.industrial-craft:industrialcraft-2
- Gradle: net.sengir.forestry
- Gradle: dev.modwarriors.notenoughkeys:NotEnoughKeys
- Gradle: qmunity:QmunityLib
- Gradle: tmech:TMechworks
- Gradle: mrtjp:ProjectRed
- Gradle: :buildcraft
- Gradle: :GalacticraftCoreAll
- Gradle: :MekanismAll
- Gradle: :redlogic
- Gradle: :CoFHLib
- Gradle: :CoFHCore
- Gradle: :MineFactoryReloaded
- Gradle: :ComputerCraft
- Gradle: :EnderIO
- Gradle: :Railcraft
- Gradle: :BloodMagic
- Gradle: :ExtraCells
- Gradle: :ThaumicEnergistics
- Gradle: api:rf
- Gradle: codechicken:CodeChickenCore
- Gradle: api:mfr
- Gradle: api:railcraft
- Gradle: appeng:mekanism
- Gradle: api:ic2
- Gradle: api:betterstorage
- Gradle: api:immibis
- Gradle: api:coloredlightscore
- Gradle: api:craftguide
- Gradle: api:rblocks
- Gradle: api:invtweaks
- Gradle: appeng:Waila
- Gradle: tconstruct:TConstruct
- Gradle: codechicken:NotEnoughItems
- Gradle: codechicken:CodeChickenLib
- Gradle: codechicken:ForgeMultipart
- Gradle: mantle:Mantle

Again, make sure you repeat this process for both `OpenComputers_api` as well as `OpenComputers_main`.

Close Project Structure window (press OK)

Open Run->Edit configurations, select Application on the left pane, and set `Use classpath of module` (left Alt+O) to `OpenComputers.main` for both `Minecraft Client` and `Minecraft Server`. This fixes the error `Error: Could not find or load main class GradleStart` if you forgot to do this step.

Build Project (Shift F9)

Make symlink called `assets` to `build\resources\main\assets` in folders `build\classes\java\main` and `build\classes\scala\main`. Otherwise textures and other assets won't work.

Select "Minecraft Client" as the run target, and run!

Keep in mind that if you want to build a .jar that can be used outside of the development environment, you need to run ./gradlew clean and then ./gradlew assemble to produce .jar with obfuscated names so that it works with normal minecraft.
