Run/Debug configuration application main class GradleStart shows as red

[RexTheCapt]

When i add a new Run/Debug application configuration and set the "Main class" to "GradleStart" it shows up as red. I am following a tutorial on youtube and when they do this step it shows up as blue

Then i did try to follow this video i get the same red text. I did do what he did but with never version.

version= 1.12.2-14.23.4.2705 mappings= snapshot_20180716 did not upgrade wrapper

When it comes to run minecraft i press the green play button and "Edit configuration" pops up instead of a minecraft client and this is the window

The error is on the bottom, "Module not specified". Try number 5 here: https://mcforge.readthedocs.io/en/latest/gettingstarted/#terminal-free-intellij-idea-configuration

[RexTheCapt]

I only get two options in the "Use classpath of module" list. "" and "forge*mdk".

@derimagia i still can't find a sollution

If you try to run it what error do you get?

[RexTheCapt]

In the build console i get the error java: invalid source release: 9, i have no idea what that means. After i have run the gradle task genIntellijRuns and edit the configuration for "Minecraft Client" the main class is still red. Updated the gradle config to use the latest forge and yesterdays mappings. If you wan't i can make a little short video that shows what i do.

Sounds like you need to set your project to be using Java 8

[RexTheCapt]

sourceCompatibility and targetCompatibility is set to 1.8 in the gradle config. So it is already setup for java 8. It was the default settings too

[derimagia]

In your IDE, similar to https://stackoverflow.com/a/26009627/9741606

[RexTheCapt]

Followed the instructions in the link, ran the gradle task setupDecompWorkspace, ran genIntellijRuns, selected minecraft client and clicked play Error: java: invalid source release: 9, checked the config for the task and same as always.

[derimagia]

You changed all of these to 8 / 1.8 right? And the JDK you have setup for the project is 1.8? (Again, in IntelliJ)

[RexTheCapt]

I am pretty sure i have done that.

Actually just started to use intellij.
