Michael Osipov updated MRESOLVER-265:
-------------------------------------
Description:
In short: repository layout has member:
*
{{org.eclipse.aether.internal.impl.Maven2RepositoryLayoutFactory.Maven2RepositoryLayout#checksumAlgorithms}}
That is checksums (as configured by user of default) that will be consumed (on
fetch) or produced (publish).
Now, if we consider "default" configured resolver (checksumAlrgorithms=SHA1,
MD5) there is a discrepancy IF ANY OTHER supported but not configured checksum
comes in play:
If a Mojo attaches an artifact having extension ".zip.sha512", resolver will
checksum it (w/ {{checksumAlgorithms}} checksums) DESPITE it should know this
is a checksum, and "checksum of a checksum" is a nonsense, just makes noise.
Reason: method
{{org.eclipse.aether.internal.impl.Maven2RepositoryLayoutFactory.Maven2RepositoryLayout#isChecksum}}
works with preconfigured checksums only (in our example SHA1 and MD5) and will
respond "not a checksum" for SHA512.
Proposal to fix:
The method check should NOT be based on {{checksumAlgorithms}} but on "all
checksums supported by Resolver".
