Maven check that all dependencies have been released

As part of my release process, I use mvn versions:use-releases goal to replace all -SNAPSHOT dependencies with released versions. After this, I want to check if all the SNAPSHOT dependencies have been replaced with releases or not.

Question: How can I check it?

I know, the maven release plugin performs such a check as part of release-prepare goal, but I don't want to use release plugin.

You can use the maven-enforcer-plugin to double check whether any SNAPSHOT dependency is still there or not.

From the official example of its requireReleaseDeps rule:

<project>
  [...]
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-enforcer-plugin</artifactId>
        <version>1.4.1</version>
        <executions>
          <execution>
            <id>enforce-no-snapshots</id>
            <goals>
              <goal>enforce</goal>
            </goals>
            <configuration>
              <rules>
                <requireReleaseDeps>
                  <message>No Snapshots Allowed!</message>
                </requireReleaseDeps>
              </rules>
              <fail>true</fail>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
  [...]
</project>

Note the fail element set to true, in this case the build would fail if any SNAPSHOT dependency was found.

You could place such configuration in a maven profile and activate it when required (hence whenever this check must be performed).
