Invalid data: Minimum JRE version should be x.x.x[_xx]

[mbachinger]

I am attempting to use this plugin with my Java application using Java 11. I keep getting the error:
net.sf.launch4j.BuilderException: Invalid data: Minimum JRE version should be x.x.x[_xx]
Does this plugin not work with Java 11?

@mbachinger take a look at the documentation mentioning

<minVersion>, <maxVersion> format - Java >= 9
The new version format is xxx[.xxx[.xxx]] where only 1 part is required and the update version after the underscore is not allowed.

• 1.6
• 9
• 10.0.1

@TheBoegl
Thanks for the reply. I am not specifying the underscore or the portion after though. I have tried:

• 11
• 11.0
• 11.0.5

I also tried setting the targetCompatibility since this overrides it.

Versions 9 and under work but 10 and 11 don't.

This is the createExe.xml being created before running into that error:

@mbachinger I've edited your answer to display your xml output as code block.
I'm unable to reproduce your error. Please provide a minimal reproducible example. Creating the executable with your provided xml works for me.

[mbachinger]

@TheBoegl Changing the Launch4j version to 2.4.4 fixed the problem.

[Sebastian Bögl]

@mbachinger Are you referring to this plugin in version 2.4.4 from 2018? To really help you please attach a failing project configuration or a link to a repository. I'm still unable to reproduce this issue.
