group = "com.github.sakebook"
version = "0.0.1"

@sakebook in the meantime, here’s a quick workaround:

diff --git a/build.gradle.kts b/build.gradle.kts
index d678bab..e012b4d 100644
--- a/build.gradle.kts
+++ b/build.gradle.kts
@@ -16,6 +17,17 @@ dependencies {

I’ll open an issue on distroless/java.

Hmm… I see.

Thank you for your workaround!

And distroless/java issue.
