Overview

The plugin checks rules and warns or fails the build if conditions are not met.

The list of rules the plugin can enforce is specified here:

https://maven.apache.org/enforcer/enforcer-rules/index.html

The enforcer version range syntax is specified here:

https://maven.apache.org/enforcer/enforcer-rules/versionRanges.html

The enforcer plugin binds to the validate phase, which is the first phase in the lifecycle.

Examples

Fail if Files Do Not Exist

Works with both files and directories. For directories, use the same <requireFilesExist>.
