Client Fails to Start When Space is in Project Path

[NovaMachina]

If the project folder is in a location with spaces in the path, the run configurations generated by NeoGradle will not start.

I was able to confirm this issue by pulling the base MDK without modifying it and placing it in the following location: /home/user/Projects/Minecraft Mods/TestProject After the project was synced and the run configuration TestProject: Client was run, the following error would occur:

Error: Could not find or load main class Mods.TestProject.build.neoForm.neoFormJoined1.20.2-20231019.002635.steps.writeMinecraftClasspath.classpath.txt
Caused by: java.lang.ClassNotFoundException: Mods.TestProject.build.neoForm.neoFormJoined1.20.2-20231019.002635.steps.writeMinecraftClasspath.classpath.txt

The actual command executed on the command line (formatted so its easier to read):

I was able to work around the issue by modifying the run configuration and putting quotes around the following arguments:

-DlegacyClassPath.file="/home/user/Projects/Minecraft Mods/TestProject/build/neoForm/neoFormJoined1.20.2-20231019.002635/steps/writeMinecraftClasspath/classpath.txt"

Confirmed for eclipse, not sure if this impacts IDEA as well

XFactHD ran into it as well: https://discord.com/channels/313125603924639766/801175194298744902/1168692397182566461, with what appears to be IDEA, though I'm not entirely certain

I have tested this myself and can confirm that it occurs in IntelliJ as well
