|---|---|---|---|---|---|
maven.build.timestamp.format |
String |

maven.consumer.pom |
Boolean |
User property for enabling/disabling the consumer POM feature. | true |
4.0.0 | User properties |
maven.deploy.snapshot.buildNumber |
Integer |
User property for overriding calculated “build number” for snapshot deploys. Caution: this property should be RARELY used (if used at all). It may help in special cases like “aligning” a reactor build subprojects build numbers to perform a “snapshot lock down”. Value given here must be maxRemoteBuildNumber + 1 or greater, otherwise build will fail. How the number to be obtained is left to user (ie by inspecting snapshot repository metadata or alike). Note: this feature is present in Maven 3.9.7 but with different key: maven.buildNumber. In Maven 4 as part of cleanup effort this key was renamed to properly reflect its purpose. |

maven.relocations.entries |
String |
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 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. |
- | 4.0.0 | User properties |
maven.repo.central |
String |
Maven central repository URL. The property will have the value of the MAVEN_REPO_CENTRAL environment variable if it is defined. |

maven.repo.local |
String |
Maven local repository. | ${maven.user.conf}/repository |
3.0.0 | User properties |
maven.repo.local.head |
String |
User property for chained LRM: the new “head” local repository to use, and “push” the existing into tail. Similar to maven.repo.local.tail, this property may contain comma separated list of paths to be used as local repositories (combine with chained local repository), but while latter is “appending” this one is “prepending”. |
- | 4.0.0 | User properties |
maven.repo.local.recordReverseTree |
String |
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. |
false |
3.9.0 | User properties |
maven.repo.local.tail |
String |
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. |
- | 3.9.0 | User properties |
maven.repo.local.tail.ignoreAvailability |
String |
User property for chained LRM: whether to ignore “availability check” in tail or not. Usually you do want to ignore it. This property is mapped onto corresponding Resolver 2.x property, is like a synonym for it. Default value: true. |
- | 3.9.0 | User properties |
maven.resolver.dependencyManagerTransitivity |
String |
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”. |
true |
4.0.0 | User properties |
maven.resolver.transport |
String |
Resolver transport to use. Can be default, wagon, apache, jdk or auto. |
default |
4.0.0 | User properties |
maven.session.versionFilter |
String |
User property for version filter expression used in session, applied to resolving ranges: a semicolon separated list of filters to apply. By default, no version filter is applied (like in Maven 3). Supported filters:
"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. Value in this property builds org.eclipse.aether.collection.VersionFilter instance. |
