Cannot Kotlin bootRun on Windows due to long paths / No auto configuration classes found in META-INF/spring.factories

[psyanite]

When I run bootRun on Microsoft Windows [Version 10.0.17134.228], it throws the error 'CreateProcess error=206' when classpath too long on the cp, but I am able to start the application with no issues, if I run java -jar meow.jar on the jar produced by bootJar.

I have tried to enable long paths via the Enable NTFS long paths option and also in REGEDIT, and then restart my machine, but no luck.

This is a common issue with typical Java projects with bootRun for a long time as seen in this github issue

So I decided to write my custom bootRun like in this github issue but have encountered another issue.

My build.gradle:

Gradle version: gradle-4.5.1-all.zip

        kotlinVersion = '1.2.51'

:bootRun FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':bootRun'.
> Process 'command 'C:\Program Files\Java\jdk-10.0.1\bin\java.exe'' finished with non-zero exit value 1

My friend who runs bootRun do not have spring.factories in his jar, I assume this is supposed to be supplied by the plugin?

I have tried ./gradlew clean before I run every ./gradlew bootRun

Thank you for taking the time to read my issue and any help will be appreciated!

[wilkinsona]

Can you please provide a minimal sample that reproduces the auto-configuration failure?

[psyanite]

Hi @wilkinsona, by 'minimal sample' you mean project correct?

[wilkinsona]

Yes, something that we can build and run that contains just enough code to reproduce the problem. It appears that something is getting the classpath wrong so the spring.factories files can't be found or it's empty. Given that there's such a file in spring-boot-autoconfigure and classes from the module have been loaded, I can't tell why that's happening at the moment.

[psyanite]

Thank you for reviewing my issue. Feel free to close the issue and I will re-open or open a new one when I can make the configurations and push the code to a public repo.
