    • MAVEN_RELOCATIONS_ENTRIES

      @Config public static final String MAVEN_RELOCATIONS_ENTRIES
      User controlled relocations. This property is a comma separated list of entries with the syntax GAV>GAV. The first GAV can contain * for any elem (so *:*:* would mean ALL, something you don't want). The second GAV is either fully specified, or also can contain *, then it behaves as "ordinary relocation": the coordinate is preserved from relocated artifact. Finally, if right hand GAV is absent (line looks like GAV>), the left hand matching GAV is banned fully (from resolving).
      Note: the > means project level, while >> means global (whole session level, so even plugins will get relocated artifacts) relocation.
      For example, 
      maven.relocations.entries = org.foo:*:*>, \\
          org.here:*:*>org.there:*:*, \\
          javax.inject:javax.inject:1>>jakarta.inject:jakarta.inject:1.0.5
      means: 3 entries, ban org.foo group (exactly, so org.foo.bar is allowed), relocate org.here to org.there and finally globally relocate (see >> above) javax.inject:javax.inject:1 to jakarta.inject:jakarta.inject:1.0.5.

    • MAVEN_VERSION_FILTERS

      @Config public static final String MAVEN_VERSION_FILTERS
      User property for version filters expression, a semicolon separated list of filters to apply. By default, no version filter is applied (like in Maven 3).
      Supported filters:
      • "h" or "h(num)" - highest version or top list of highest ones filter
      • "l" or "l(num)" - lowest version or bottom list of lowest ones filter
      • "s" - contextual snapshot filter
      • "e(G:A:V)" - predicate filter (leaves out G:A:V from range, if hit, V can be range)
      Example filter expression: "h(5);s;e(org.foo:bar:1) will cause: ranges are filtered for "top 5" (instead full range), snapshots are banned if root project is not a snapshot, and if range for org.foo:bar is being processed, version 1 is omitted.

      4.0.0
      See Also:

    • MAVEN_REPO_LOCAL_TAIL

      @Config public static final String MAVEN_REPO_LOCAL_TAIL
      User property for chained LRM: list of "tail" local repository paths (separated by comma), to be used with org.eclipse.aether.util.repository.ChainedLocalRepositoryManager. Default value: null, no chained LRM is used.
      Since:
      3.9.0

    • MAVEN_REPO_LOCAL_RECORD_REVERSE_TREE

      @Config(defaultValue="false") public static final String MAVEN_REPO_LOCAL_RECORD_REVERSE_TREE
      User property for reverse dependency tree. If enabled, Maven will record ".tracking" directory into local repository with "reverse dependency tree", essentially explaining WHY given artifact is present in local repository. Default: false, will not record anything.
      Since:
      3.9.0
      See Also:

    • MAVEN_RESOLVER_DEPENDENCY_MANAGER_TRANSITIVITY

      @Config(defaultValue="true") public static final String MAVEN_RESOLVER_DEPENDENCY_MANAGER_TRANSITIVITY
      User property for selecting dependency manager behaviour regarding transitive dependencies and dependency management entries in their POMs. Maven 3 targeted full backward compatibility with Maven2, hence it ignored dependency management entries in transitive dependency POMs. Maven 4 enables "transitivity" by default, hence unlike Maven2, obeys dependency management entries deep in dependency graph as well.
      Default: "true".
      Since:
      4.0.0
      See Also:

    • MAVEN_RESOLVER_TRANSPORT
