To check how "1.2.7" compares to "1.2-SNAPSHOT", for example, you can issue
java -jar ${maven.repo.local}/org/apache/maven/maven-artifact/${maven.version}/maven-artifact-${maven.version}.jar "1.2.7" "1.2-SNAPSHOT"command to command line. Result of given command will be something like this:
Display parameters as parsed by Maven (in canonical form) and comparison result: 1. 1.2.7 == 1.2.7 1.2.7 > 1.2-SNAPSHOT 2. 1.2-SNAPSHOT == 1.2-snapshot
args
- the version strings to parse and compare. You can pass arbitrary number of version strings and always
