dependency-check-maven-plugin

Strictly check that dependencies were properly declared in a maven project. The project target classes are examined at the byte code level to determine which classes are required to compile the project. From the class dependencies, the jar level dependencies are found. This plugin detects "declared but unused" and "used but undeclared" dependencies.

Goals

There are two goals: main checks the main target classes; and test checks the test target classes.

Parameters

The followings parameters can be set with a maven property dependency-check.<parameter_name>. e.g. skip parameter can be set from command line -D dependency-check.skip=true

Parameter	Default	Description
fail	true	Fail build when incorrect declarations found
skip	false	Skip execution of plugin

The following parameters are sets of dependencies which are to be ignored in various ways. Each of these parameters are filters.

Parameter	Description
ignoreDependencies	Ignore incorrect declarations of these dependencies
ignoreUnusedDeclaredDependencies	Ignore dependencies if they are declared but unused
ignoreUsedUndeclaredDependencies	Ignore dependencies if they are used but undeclared

Filter Syntax

Dependency filters have multiple segments: [groupId]:[artifactId]:[type]:[version]. Each filter segment is optional and supports full and partial * wildcards. An empty pattern segment is treated as an implicit wildcard.

Requirements

• Maven 3.5 or later
• Java 11 or later
