Hi Hanish, I see child1 in my Maven local repository cannot resolve the $version to refer to its parent, because $version is defined at the parent (the error message below).
How about specifying the concrete version when specifying parent? While you might not like that the version value will appear multiple places, you can update them by "mvn version:set" https://www.mojohaus.org/versions-maven-plugin/set-mojo.html [ERROR] Failed to execute goal on project child2: Could not resolve dependencies for project com.sample:child2:jar:1.1.0-SNAPSHOT: Failed to collect dependencies at com.sample:child1:jar:1.1.0-SNAPSHOT: Failed to read artifact descriptor for com.sample:child1:jar:1.1.0-SNAPSHOT: Could not find artifact com.sample:test-parent:pom:${revision} in central ( https://repo.maven.apache.org/maven2) -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
