class GrapeChecksumPolicyProvider
extends Object
implements ChecksumPolicyProviderSupplies the checksum policy Grape uses for remote artifact downloads.
Maven Resolver's stock CHECKSUM_POLICY_FAIL rejects a download both when a
published checksum does not match and when no checksum is published at all. Grape wants
only the first of those: a mismatch means the bytes are not what the repository said they
would be and must never reach the classpath, whereas a repository that simply publishes no
.sha1/.md5 is a common and legitimate situation, particularly for internal
and older repositories.
This provider therefore delegates to the stock org.eclipse.aether.spi.connector.checksum.ChecksumPolicyProvider for every
policy and wraps only the fail policy, relaxing its
org.eclipse.aether.spi.connector.checksum.ChecksumPolicy#onNoMoreChecksums() response. The result matches the semantics the
Ivy-backed engine has always had, so both Grape engines behave alike.
