JarCastingDependency Version Maven Plugin
A plugin that sets properties to the resolved versions of project dependencies.
Use-case
Your project depends on something with a transitive dependency. You need to know the version of that transitive dependency, but you do not want to hard-code the version in your project as you are purely relying on it being controlled by the dependency that is pulling it in transitively.
For example, if you depend on jackson-dataformat-yaml that will pull in a transitive dependency on snakeyaml, your code’s sanity checks may want to complain if your code is run with a different version of snakeyaml.
How to use
Add an execution of the plugin to your project and the properties you define will be available for resource filtering as well as other Mojo executions after this plugin has executed, e.g.
...
<plugins>
<plugin>
<groupId>com.github.stephenc.continuous</groupId>
<artifactId>dependency-version-maven-plugin</artifactId>
<version>...</version> (1)
<executions>
<execution>
<goals>
<goal>set</goal>
</goals>
<configuration>
<properties>
<property> (2)
<name>snakeyamlVersion</name> (3)
<!-- groupId>org.yaml</groupId--> (4)
<artifactId>snakeyaml</artifactId> (5)
</property>
</properties>
</configuration>
</execution>
</executions>
</plugin>
</plugins>

You must specify the name of each property you want to set. Because you will most likely be using these properties in resource filtering, recommendation is not to use a name containing a

If there are multiple dependencies with the target
artifactIdand differentgroupIdthen you will need to specify the target groupId. -
You must specify the
artifactIdof the dependency who’s version you wish to capture.
