Mirko Friedenhagen commented on MNG-5728: ----------------------------------------- Hello Michael, I would recommend: * open an issue at OSSRH * download and check the corrupt artifacts and either * install them to your local cache or * deploy them to your local repository manager. > Switch the default checksum policy from "warn" to "fail" > -------------------------------------------------------- > > Key: MNG-5728 > URL: https://issues.apache.org/jira/browse/MNG-5728 > Project: Maven > Issue Type: Improvement > Components: Artifacts and Repositories > Reporter: Nicolas Juneau > Priority: Minor > > The default checksum policy when obtaining artifacts during a build is > currently, by default, "warn". This seems a bit odd for me since a checksum > is usually used to prevent the use of corrupted data. > Since Maven produces a lot of output (and some IDEs sometimes hide it), it is > easy to miss a bad checksum warning. I am aware that there is a > checksumPolicy setting in Maven, but, unless I am mistaken, it cannot be > defined for all repositories at once. It has to be done either on a > per-repository basis or by using the "strict-checksum" flag in the command > line. > After searching around a bit on the Web and with the help of a coworker, we > discovered that the default "warn" setting was mainly there because some > repositories were not handling checksums quite well. Issue MNG-339 contains > some information about this. > My colleague also chatted briefly with "trygvis" on IRC. Apparently, the > default "warn" setting is really there for historical reasons. > I believe that a default value of "fail" would greatly reduce the likelihood > of errors and also slightly increase the security of Maven. Corrupted > artifacts should not, by default, be used for builds. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
