Herve Boutemy updated MBUILDCACHE-16:
-------------------------------------
Description:
reported to me by someone trying to test:
I've noticed that all the docs state a file named maven-cache-config.xml but
the source suggests it should be called maven-build-cache-config.xml:
https://github.com/apache/maven-build-cache-extension/blob/c92e48ef924e0f67a0e1299[…]/main/java/org/apache/maven/buildcache/xml/CacheConfigImpl.java
Also maybe worth stating that the XXMM (memory mapped files) hash algorithm
seems to require JDK9+ as it uses ByteBuffer.clear() somewhere - or at least,
when I tried to use it, I saw a stacktrace with that - maybe some other
extension/plugin interacting badly. It only seemed to happen with XXMM.
