In Maven repositories, changing versions are commonly referred to as link:https://maven.apache.org/guides/getting-started/index.html#what-is-a-snapshot-version[snapshot versions].
Snapshot versions contain the suffix `-SNAPSHOT`.
The following example demonstrates how to declare a snapshot version on the Spring dependency.

.Declaring a dependency with a changing version
====

        assertTrue(range.containsVersion(new DefaultArtifactVersion("1.1-SNAPSHOT")));
        assertTrue(range.containsVersion(new DefaultArtifactVersion("1.2-SNAPSHOT")));

        range = VersionRange.createFromVersionSpec("[1.0-SNAPSHOT,1.2]");

        assertTrue(range.containsVersion(new DefaultArtifactVersion("1.0-SNAPSHOT")));

        when(project.getPackaging()).thenReturn("jar");
        when(project.getName()).thenReturn("Apache Maven Embedder");
        when(project.getVersion()).thenReturn("3.5.4-SNAPSHOT");
        when(project.getFile()).thenReturn(new File(basedir, "maven-embedder/pom.xml"));
        when(event.getProject()).thenReturn(project);

        MavenProject rootProject = mock(MavenProject.class);
