There was a problem hiding this comment. Is it really implementation specific? Not just that there simply isn't a mask? How many implementations are there? There was a problem hiding this comment. Yes, it is. It is implementation-specific, because it depends on Plexus Archiver internals. Refer to that comment for details, please. |

Current implementation of Plexus Archiver (used by Maven Assembly Plugin) -
org.codehaus.plexus.archiver.AbstractArchiverclass - applies its default umask (which is022) only whenconfigureReproducibleBuildmethod is called. Current version of Maven Assembly Plugin invokes that method only whenproject.build.outputTimestampmaven property is specified. It means that0as value ofoverrideUmaskconfiguration option changes behavior of Maven Assembly Plugin only whenproject.build.outputTimestampmaven property is specified. It's sad (complicated for the users of Maven Assembly Plugin) behavior, but it's an issue of Plexus Archiver, which should not apply its default umask to file/directory permissions for the case when both conditions are met:fileMode/directoryModeare defined forfileSet(as far as I understand, bothfileModeanddirectoryModeoptions offileSethave default values -0644and0755respectively - so it means that this condition is always true).tar,zipandjar) supports configuration of file/directory permissions independent of OS.This is the reason
overrideUmaskconfiguration option of Maven Assembly Plugin is introduced:0asoverrideUmaskconfiguration option to explicitly override umask which is sometimes (see above) implicitly used by Plexus Archiver.dir- supports setting same permissions as defined in assembly descriptor or source file/directory has in an OS independent way).There was a problem hiding this comment.

I'm losing the plot here, but it sounds like maybe this is something that should be fixed in plexus-archvier instead? If a fix there could avoid adding extra complexity and API here that would be preferable.

Additional public API is too heavyweight a solution for a bug that can be fixed at the source.

Maven users use Assembly plugin and not Plexus Archiver, so for the users of Maven it is a bug of Assembly plugin introduced in 3.6.0 version (by migration to the new version of Plexus Archiver). We can provide a quick workaround. Changing Plexus Archiver is too complex. It can require Plexus Archiver API change and change of Assembly plugin. Unfortunately, I won’t be able to help with this kind of changes (I am even not the author of this pull request).
Assembly plugin already has
override*configuration options, which are close tooverrideUmaskconfiguration option (which are the same sort workaround). IMHO, it’s a trade-off which Maven maintainers decide if they agree or not. I tried my best to provide all details for making informed decision :)There was a problem hiding this comment.

I do not agree with new public API as a quick workaround. If the bug was introduced by a new version of plexus archiver, then revert to the old version as a workaround until plexus archiver is fixed.
New public API needs to be justified on its own merits.

I'm not sure "override" means the same thing in both cases. If I'm following this, in the other cases the override replaces the existing GIDs, UIDs, etc. set on the files being added to the assembly. In this case it's not doing that. Rather it's changing the behavior of the plugin.

Maven Assembly Plugin 3.6.0 is not compatible with older version of Plexus Archiver (that was the first thing I tried to workaround this bug), so there is no way to "revert to old version" of Plexus Archiver when using Maven Assembly Plugin 3.6.0. Instead my team has to stay on 3.5.0 version of Maven Assembly Plugin (which cases some "false" warnings when used with Maven 3.9.x).

I meant the following Assembly plugin configuration options:
overrideUidoverrideUserNameoverrideGidoverrideGroupNameare similar to this pull request, because instead of setting these values in Assembly plugin configuration, they had to be a part of respective sections of assembly descriptor - just like
fileModeanddirectoryModeare part offileSetsection of assembly descriptor. Unfortunately, that change was more complex and required changes in API of Plexus Archiver (which I was working on). It seems that maintainers of Assembly plugin decided to chose simpler (but less generic / agile) path, which is the same as this pull request suggests.
