Configuration Options

Key Type Description Default Value Since Source
maven.build.timestamp.format String Build timestamp format. yyyy-MM-dd'T'HH:mm:ssXXX 3.0.0 Model properties
maven.build.version String Maven build version: a human-readable string containing this Maven version, buildnumber, and time of its build. - 3.0.0 system_properties
maven.builder.maxProblems Integer Max number of problems for each severity level retained by the model builder. 100 4.0.0 User properties
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. - 4.0.0 User properties
maven.ext.class.path String Extensions class path. - User properties
maven.home String Maven home. - 3.0.0 system_properties
maven.installation.conf String Maven installation configuration directory. ${maven.home}/conf 4.0.0 User properties

maven.logger.cacheOutputStream Boolean If the output target is set to “System.out” or “System.err” (see preceding entry), by default, logs will be output to the latest value referenced by System.out/err variables. By setting this parameter to true, the output stream will be cached, i.e. assigned once at initialization time and re-used independently of the current value referenced by System.out/err. false 4.0.0 User properties
maven.logger.dateTimeFormat String The date and time format to be used in the output messages. The pattern describing the date and time format is defined by SimpleDateFormat. If the format is not specified or is invalid, the number of milliseconds since start up will be output. - 4.0.0 User properties
maven.logger.defaultLogLevel String Default log level for all instances of SimpleLogger. Must be one of (“trace”, “debug”, “info”, “warn”, “error” or “off”). If not specified, defaults to “info”. - 4.0.0 User properties
maven.logger.levelInBrackets Boolean Should the level string be output in brackets? Defaults to false. false 4.0.0 User properties
maven.logger.logFile String The output target which can be the path to a file, or the special values “System.out” and “System.err”. Default is “System.err”. - 4.0.0 User properties
maven.logger.showDateTime Boolean Set to true if you want the current date and time to be included in output messages. Default is false. false 4.0.0 User properties
maven.logger.showLogName Boolean Set to true if you want the Logger instance name to be included in output messages. Defaults to true. true 4.0.0 User properties
maven.logger.showShortLogName Boolean Set to true if you want the last component of the name to be included in output messages. Defaults to false. false 4.0.0 User properties

maven.modelBuilder.parallelism Integer ProjectBuilder parallelism. cores/2 + 1 4.0.0 User properties
maven.plugin.validation String Plugin validation level. inline 3.9.2 User properties
maven.plugin.validation.excludes String Plugin validation exclusions. - 3.9.6 User properties
maven.project.conf String Maven project configuration directory. ${session.rootDirectory}/.mvn 4.0.0 User properties
maven.project.extensions String Maven project extensions. ${maven.project.conf}/extensions.xml 4.0.0 User properties
maven.project.settings String Maven project settings. ${maven.project.conf}/settings.xml 4.0.0 User properties
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
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.		 - 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. https://repo.maven.apache.org/maven2 4.0.0 User properties
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” 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. Value in this property builds org.eclipse.aether.collection.VersionFilter instance.		 - 4.0.0 User properties
