Test Client not launching Linux

[Ilovecatfood]

In the terminal cd into my mods folder, and ran ./gradlew runClient, 

the window pops up for about half a second then shuts down again.

Can somebody please help me, I am a noob.

 

I am using ubuntu, forge mdk 1.16.5.

 

 this is the terminal output.

[main/FATAL] [ne.mi.fo.la.MavenVersionAdapter/]: Failed to parse version spec [1.16.5)
org.apache.maven.artifact.versioning.InvalidVersionSpecificationException: Single version must be surrounded by []: [1.16.5)

This is the line telling you the error, [1.16.5) is not a valid version range

 

Look at section 7.3 on the documentation: https://docs.oracle.com/middleware/1212/core/MAVEN/maven_version.htm#MAVEN402

it tells you how to write a semantically valid version range
