Ok... I have researched a bit more... Since Minecraft Forge 1.13.2-25.0.28 (released 5 hours ago), after running gradlew eclipse, we shall run gradlew genEclipseRuns This new gradlew task will create "runClient.launch" and "runServer.launch" configurations. But it is not necessary to import them. The task already does this automatically, including them into the Eclipse project. I've just tried myself, and it works as it should: the mod is compiled/built, Minecraft runs, and the mod is loaded. I can't guarantee that it will be the same tomorrow (we had 8 Forge releases this Monday!)

What worked for me yesterday is already obsolete today. While we discuss here, the developers have been fixing and changing ForgeGradle and the Eclipse launch configurations code. If yesterday we had "client.launch" and "server.launch" files at project root... today we do not have them anymore! New related commits have been merged into Forge around 5 hours ago: https://github.com/MinecraftForge/ForgeGradle/pull/546 https://github.com/MinecraftForge/MinecraftForge/pull/5482 https://github.com/MinecraftForge/MinecraftForge/commit/2e2c57dbd104b24a2bfe15194231cf9f2ca904d9 https://github.com/MinecraftForge/MinecraftForge/commit/1a833a9267cb030dd1592d65b05337b6af968adb I will just wait a bit so new version(s) with these changes are released.

I've just completed my first Eclipse workspace setup for Minecraft mod development using Forge for Minecraft 1.13.2 I can successfully launch Minecraft 1.13.2 from inside Eclipse, with the mod properly loaded by Forge. You need to import the launch configurations in Eclipse. The launch configuration files, "client.launch" and "server.launch" can be found in the project root folder, after you ran "gradlew eclipse". To import then, go to File > Import... and then expand Run/Debug select Launch Configurations, and click Next. Browse and select your mod project root folder. Check the project checkbox in the left panel, and select the launch configurations in the right panel. Click Finish to import. Screenshots here: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0446g/CJADBBIA.html The imported launch configurations are available for usage now... go to Run > Run Configurations... and select the client configuration to launch Minecraft with your mod loaded.
