Hi,

Last year we mark all Maven versions 3.6.x and older as EOL [1]

But we still try to support minimal API version for Core Maven Plugins as
3.2.5

I would like to  propose to sich it for at least to 3.6.3

Reasonable reasons: (for me)
   - for standard CI build we use Maven 3.6.3 and newer
   - many of external plugins, like MojoHaus are switched to 3.6.3
   - we have a hacks in code to try support old version in plugin, like
in: EnhancedPluginDescriptorBuilder in plugin-tools [2], we can cleanup
such code
- I don't believe to someone want to do more fixes for EOL Maven version
in
plugins - so we should be a honest for users
- and we should go forward

[1] https://maven.apache.org/docs/history.html
[2]

https://github.com/apache/maven-plugin-tools/blob/master/maven-plugin-report-plugin/src/main/java/org/apache/maven/plugins/plugin/descriptor/EnhancedPluginDescriptorBuilder.java


I remember that we had a discussion that the next base/API version
should be 3.5.4 because it is the first version using
org.apache.maven.resolver:maven-resolver-api [1]. Please don't confuse
API compat with maintenance/support for a specific Maven version. I
believe that we have made this clear more than once.

Is thre anything specific fixed in 3.6.3 behavior you consider crucial
which makes maintenance easier than with 3.5.4?


I remember the discussion ... and next year we are still on 3.2.5

I can not a list what was exactly improved in 3.6.3 against to 3.5.4, but I
see in mentioned code

  // clear() is required for maven < 3.6.2
  mojoDescriptor.getParameters().clear();

This one is moot and incorrect. I will change the comment. The real improvement has been done by Tamás in 4.0.0-alpha-1: https://github.com/apache/maven/commit/cc51006f2973356a1046ae0757325d5e9be75327

So my question is:

Why should we use 3.5.4 instead of 3.6.4 as minimum in plugins?

If you can provide some real examples where 3.6.x is better/easier I will happily accept it.

Michael
