Re: [jakartaee-spec-project-leads] How to recognize the latest version of artifacts in central?
|
Lukas is right, using the maven-artifact tool it says 4.0.0.M1 > 4.0.0-RC1
java -jar %MAVEN_HOME%\lib\maven-artifact-3.6.3.jar 4.0.0.M1 4.0.0-RC1
Display parameters as parsed by Maven (in canonical form) and comparison result:
1. 4.0.0.M1 == 4.0.0.milestone-1
4.0.0.M1 > 4.0.0-RC1
2. 4.0.0-RC1 == 4-rc-1
java - jar %MAVEN_HOME%\lib\maven-artifact-3.6.3.jar 4.0.0-RC1 4.0.0.M1
Display parameters as parsed by Maven (in canonical form) and comparison result:
1. 4.0.0-RC1 == 4-rc-1
4.0.0-RC1 < 4.0.0.M1
2. 4.0.0.M1 == 4.0.0.milestone-1
We can conclude from above 4.0.0-RC1 becomes 4-rc-1 whereas 4.0.0.M1 becomes 4.0.0-milestone-1.
If we have 4.0.0-M1 and compare with 4.0.0-RC1 then it becomes 4-milestone-1 < 4-rc-1
If we have 4.0.0.RC1 and compare with 4.0.0-RC1 then it becomes 4.0.0-rc1 > 4-rc-1
Thanks
Hussain

I'm not talking about version number recognition, I'm talking about proper version ordering, so one can rely on available tooling to save some time and use automation to take care of updating dependencies.

https://apc01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fmaven.apache.org%2Fpom.html%23Version_Order_Specification&data=02%7C01%7Chussain.nm%40cognizant.com%7C8499180385e74d5e233d08d801bfe1ed%7Cde08c40719b9427d9fe8edf254300ca7%7C0%7C0%7C637261270941831432&sdata=oPPtZlzsOrVOHf3ytLeyX1rRdyyZrYd9wnOIz0hqIo0%3D&reserved=0 explains it
- '.' is a version number separator, while '-' is not, so:
4.0.0-RC1 has 3 parts - 4, 0, 0-RC1
4.0.0.M1 has 4 parts - 4, 0, 0, M1
and maven compares 3rd part - '.0-RC1' with '.0' and if I got it right, ".qualifier" < ".number" applies => '.0-RC1' < '.0', so in the end '4.0.0-RC1' < '4.0.0.M1'
