Can't compile gradle: asm-parent-4.0.jar is missing from

Caused by: org.gradle.api.UncheckedIOException: Could not HEAD ‘’. Received status code 503 from server: Service Unavailable

Sounds like the repository was down. This happens from time to time. Try again a bit later.

I can see the other files here: but not the jar…

There is no Jar for ‘asm-parent’, not even on Maven Central. However this is not the problem. The problem is that you got 503: service unavailable.

it finally compiled. thanks for the reply
