Checking for new dependency updates
# Checking for new dependency updates

The <<<display-dependency-updates>>> goal will check all the dependencies used in your project and display a list
of those dependencies with newer versions available.

Advancing dependency versions
=============================

There are a number of goals which can be used to advance dependency versions:

- [versions:use-next-releases](../use-next-releases-mojo.html) searches the pom for all non-SNAPSHOT versions which
have been a newer release and replaces them with the next release version.
- [versions:use-latest-releases](../use-latest-releases-mojo.html) searches the pom for all non-SNAPSHOT versions
which have been a newer release and replaces them with the latest release version.
- [versions:use-next-snapshots](../use-next-snapshots-mojo.html) searches the pom for all non-SNAPSHOT versions
which have been a newer -SNAPSHOT version and replaces them with the next -SNAPSHOT version.
- [versions:use-latest-snapshots](../use-latest-snapshots-mojo.html) searches the pom for all non-SNAPSHOT versions
which have been a newer -SNAPSHOT version and replaces them with the latest -SNAPSHOT version.
- [versions:use-next-versions](../use-next-versions-mojo.html) searches the pom for all versions which
have been a newer version and replaces them with the next version.
[versions:use-latest-versions](../use-latest-versions-mojo.html) searches the pom for all versions which
have been a newer version and replaces them with the latest version.

All of these goals share a common set of parameters.

Deciding which goal to use
--------------------------

The following matrix should help decide which goal(s) to use:

| Goal | Modifies Release dependencies | Modifies -SNAPSHOT dependencies | Considers releases | Considers -SNAPSHOTs | Picks Next | Picks Latest |
|----------------------|:-----------------------------:|:-------------------------------:|:------------------:|:------------------------:|:----------:|:------------:|
| use-next-releases | | Yes | Yes | | Yes | |
| use-latest-releases | | Yes | Yes | | | Yes |
| use-next-snapshots | Yes | | | Yes | Yes | |
| use-latest-snapshots | Yes | | | Yes | | Yes |
| use-next-versions | Yes | Yes | Yes | If -DallowSnapshots=true | Yes | |
| use-latest-versions | Yes | Yes | Yes | If -DallowSnapshots=true | | Yes |

The columns in the above goal matrix are as follows:

- *Modified Release dependencies* when scanning the `pom.xml` for dependency to update, include those dependencies which
are for release versions (i.e. non-SNAPSHOT versions).
- *Modified -SNAPSHOT dependencies* when scanning the `pom.xml` for dependency to update, include those dependencies which
are for -SNAPSHOT versions.
- *Considers releases* when building the list of newer versions of a dependency, include release versions (i.e. non-SNAPSHOT
versions) in the list.
- *Considers releases* when building the list of newer versions of a dependency, include -SNAPSHOT versions in the list.
- *Picks Next* when the list of newer versions is sorted in increasing order, pick the first newer version in the list, i.e.
the oldest newer version available, also known as the "next" version.
- *Picks Latest* when the list of newer versions is sorted in increasing order, pick the last newer version in the list, i.e.
the newest version available, also known as the "latest" version.

Controlling which dependencies are processed
--------------------------------------------

You can restrict which dependencies should be processed. For example,
the following will only match dependencies that match the groupId "org.codehaus.plexus" and artifactId
"plexus-utils"

```sh
mvn versions:use-next-releases -Dincludes=org.codehaus.plexus:plexus-utils
```

The `includes` and `excludes` parameters follow the format `groupId:artifactId:type:classifier`.
Use a comma separated separated list to specify multiple includes. Wildcards (\*) can also be used to match
multiple values.

This example will match anything with the groupId "org.codehaus.plexus" and anything with the groupId and
artifactId matching "junit".

```sh
mvn versions:use-next-releases -Dincludes=org.codehaus.plexus:*,junit:junit
```

You can pre-configure defaults for `includes` and `excludes` in your `pom.xml` if there is a specific
set of dependencies that you need to track on a regular basis, e.g.

```xml
<project>
...
<build>
...
<plugins>
...
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>versions-maven-plugin</artifactId>
<version>${pluginVersion}</version>
<configuration>
...
<includes>
<include>org.codehaus.plexus:*</include>
<include>junit:junit</include>
</includes>
...
<excludes>
<exclude>org.codehaus.plexus:plexus-utils</exclude>
</excludes>
...
</configuration>
</plugin>
...
</plugins>
...
</build>
...
</project>
```

By default, both the `project/dependencyManagment` and `project/dependencies` sections will be processed.
You can use the `processDependencies` and `processDependencyManagement` parameters to control which sections
are processed.

This example will only process the `project/dependencyManagment` section of your pom:

```sh
mvn versions:use-next-releases -DprocessDependencies=false
```

While this example will only process the `project/dependencies` section of your pom:

```sh
mvn versions:use-next-releases -DprocessDependencyManagement=false
```
