 ## Ignoring versions
 
 You can define which versions should be ignored using the
-`IGNORED_VERSIONS` OS environment variable which will be passed to the
-maven versions plugin as `maven.version.ignore` (see here for
-[details](https://www.mojohaus.org/versions/versions-maven-plugin/version-rules.html#Using_the_maven.version.ignore_property)).
-For example, you can set `IGNORED_VERSIONS` to
-`(?i).+-(alpha|beta).+,(?i).+-m\\d+,(?i).+-rc\\d+` to ignore alpha,
-beta, mark or release candidate versions.
+`maven.version.ignore` system property (see here for
+[details](https://www.mojohaus.org/versions/versions-maven-plugin/version-rules.html#Using_the_maven.version.ignore_property)). To
+set `maven.version.ignore` inside the Docker container, you need to
+override the default `MAVEN_CLI_OPTS` OS environment variable which
+will be passed to the maven CLI command. For example, you can set
+`MAVEN_CLI_OPTS` to `-DprocessDependencyManagementTransitive=false -Dmaven.version.ignore=(?i).+-(alpha|beta).+,(?i).+-m\\d+,(?i).+-rc\\d+`
+to ignore transitive dependencies and all alpha, beta, mark or release
+candidate versions.
