Description

Most com.fasterxml.jackson occurrences were wrapped in mustache-variables as part of #23023. After this, most Java generators fail to populate this variable, leading to null/empty.

This results in java imports like;

// Expected
import com.fasterxml.jackson.databind.util.StdDateFormat;
// Actual
import .databind.util.StdDateFormat;

This also results in pom.xml dependency declarations like;

<!-- Expected -->
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>${jackson-version}</version>
</dependency>
<!-- Actual -->
<dependency>
  <groupId>.core</groupId>
  <artifactId>jackson-core</artifactId>
  <version>${jackson-version}</version>
</dependency>

See my comment here: #23023

There are also tests in openapi-generator itself that validate that the new flags work. If you can reproduce after using the latest snapshot version (you might need to build it locally) please provide an example project so we can see what's happening there.
