This should look something like this (if you installed it directly from Oracle): C:Program FilesJavajdk1.8.0191bin.

Next, click OK. Now, create the JAVAHOME system variable.

The path that goes into this one should be exactly the same as the last one, except for the lack of bin.

This is the latest and final version of mappings for 1.12.2.

These steps are technically optional, but it is good practice to keep up-to-date with mappings, and using a newer version of Gradle will help speed up the build process and setup commands.

The easiest way to do that is by importing the project as a Gradle project.

This allows you to run Gradle tasks directly from your IDE, meaning that you can build or set up your project, update the Forge version, and more, without touching the command line or leaving Eclipse.

Name this folder whatever you would like your project to be named.

Next, open up Eclipse and point the workspace to your workspace folder.

However, we need to make sure that Eclipse is configured to use the JDK, because it uses the JRE by default (for some reason).

To change this, go to Window Preferences Java Installed JREs.

Click Add. Standard VM and enter the path of the JDK (usually C:Program FilesJavajdk1.8.0191 ).

Click Finish to add the JDK and make sure it is selected.

Finally, select the project and press F5 to refresh it (or the run configurations wont show up).
