To check for plugin or dependency updates of a Maven project the
...
Versions Maven Plugin has two interesting mojos:
...
| Code Block | ||
|---|---|---|
| ||
mvn versions:display-plugin-updates |
...
mvn versions:display-dependency-updates |
...
Unfortunately the command line is a bit long. Cumbersome to type, not that easy to remember. Using the
...
Alias Maven Plugin the command line can be shortened to:
...
| Code Block | ||
|---|---|---|
| ||
pu du |
...
In addition to that checking a project for declaring all dependencies (that is not relying on transitive dependencies) or not declaring unused dependencies is a common task to keep the project dependencies clean. The
...
Maven Dependency Plugin provides the analyze mojo for this:
...
| Code Block | ||
|---|---|---|
| ||
mvn dependency:analyze |
...
In short this would be
...
| Code Block | ||
|---|---|---|
| ||
a |
The configuration to make this work looks like this:
...
| Code Block | ||
|---|---|---|

<comment> Analyzes the dependencies of this project and determines which are: used and declared; |

used and undeclared; unused and declared. This goal is intended to be used standalone, |

thus it always executes the test-compile phase - use the dependency:analyze-only |
...
goal instead when participating in the build lifecycle. |
