Weird dependence version resolution (compare)

Tomas_Prochazka · May 7, 2020, 2:06pm

I found that Gradle consider 3.0.0-alpha49-SNAPSHOT as smaller than 3.0.0-alpha45.
It is very strange.

I tried use

apache/maven/blob/master/maven-artifact/src/main/java/org/apache/maven/artifact/versioning/ComparableVersion.java

package org.apache.maven.artifact.versioning;

And it compare it as I would expect

There are event able to compare alpha vs beta according

       private static final List<String> QUALIFIERS =
                Arrays.asList( "alpha", "beta", "milestone", "rc", "snapshot", "", "sp"  );

        private static final Properties ALIASES = new Properties();
        static
        {
            ALIASES.put( "ga", "" );
            ALIASES.put( "final", "" );
            ALIASES.put( "release", "" );
            ALIASES.put( "cr", "rc" );
        }

What Gradle is using for maven dependency compare?

I found this

github.com

gradle/gradle/blob/master/subprojects/dependency-management/src/main/java/org/gradle/api/internal/artifacts/ivyservice/ivyresolve/strategy/StaticVersionComparator.java

package org.gradle.api.internal.artifacts.ivyservice.ivyresolve.strategy;

import com.google.common.collect.ImmutableMap;

It looks much simpler.
Why are you not using algorithms compatible with maven, since it is using a better working concept?
