Java 8 compatibility

[gigitalz]

I run into this issue in version 0.15.0 upon compilation. 0.14.0 works fine.

Any workaround to use 0.15.0 ?

[nsk90]

looks like a bug, I will check and rebuild if necessary to be compatible with java 8.

I reproduced this issue on a library from maven central. (using java8 for gradle in a sample project) Moreover artefact on maven central is not backward compatible with kotlin older than 1.7.

But my local builds of the same version are working as expected. And this issue is not reproduced. I'm confused.

[nsk90]

this issue is not resolved yet.

now artifacts from maven central and jitpack work the same way.

java8 + kotlin 1.6 and 1.7 works on my sample project (1.4 & 1.5 does not) (tested on library version 0.18.0)

Sure but the issue was with Java 8 in my case, so it should be gone.
