Built-In Rules

The following built-in rules ship along with the enforcer plugin:

• alwaysFail - Always fail... used to test plugin configuration.
• alwaysPass - Always passes... used to test plugin configuration.
• banDependencyManagementScope - bans all scope values except for 'import' from dependencies within the dependency management.
• banDistributionManagement - enforces that project doesn't have distributionManagement.
• banDuplicatePomDependencyVersions - enforces that the project doesn't have duplicate declared dependencies.
• banDynamicVersions - bans all dependencies requiring version resolution at build time (i.e. version ranges, placeholders RELEASE/LATEST or SNAPSHOT versions).
• bannedDependencies - enforces that excluded dependencies aren't included.
• bannedPlugins - enforces that specific plugins aren't included in the build.
• bannedRepositories - enforces to not include banned repositories.
• banTransitiveDependencies - enforces that project doesn't have transitive dependencies.
• dependencyConvergence - ensure all dependencies converge to the same version.
• evaluateBeanshell - evaluates a beanshell script.
• externalRules - evaluate rules from an external resource.
• reactorModuleConvergence - enforces that a multi module build follows best practice.
• requireActiveProfile - enforces one or more active profiles.
• requireEnvironmentVariable - enforces the existence of an environment variable.
• requireExplicitDependencyScope - enforces that all dependencies have an explicit scope.
• requireFileChecksum - enforces that the specified file has a certain checksum.
• requireFilesDontExist - enforces that the list of files does not exist.
• requireFilesExist - enforces that the list of files does exist.
• requireFilesSize - enforces that the list of files exists and is within a certain size range.
• requireJavaVendor - enforces the JDK vendor.
• requireJavaVersion - enforces the JDK version.
• requireMatchingCoordinates - enforces specific group ID and/or artifact ID patterns.
• requireMavenVersion - enforces the Maven version.
• requireNoRepositories - enforces to not include repositories.
• requireOS - enforces the OS / CPU Architecture.
• requirePluginVersions - enforces that all plugins have a specified version.
• requirePrerequisite - enforces that prerequisites have been specified.
• requireProfileIdsExist - enforces the existence of profiles specified on the commandline.
• requireProperty - enforces the existence and values of properties.
• requireReleaseDeps - enforces that no snapshots are included as dependencies.
• requireReleaseVersion - enforces that the artifact is not a snapshot.
• requireSnapshotVersion - enforces that the artifact is not a release.
• requireSameVersions - enforces that specific dependencies and/or plugins have the same version.
• requireTextFileChecksum - enforces that the specified text file has a certain checksum (after normalizing line separators).
• requireUpperBoundDeps - ensures that every (transitive) dependency is resolved to its specified version or higher.

You may also create and inject your own custom rules by following the maven-enforcer-rule-api instructions.
