Tamas Cservenak updated MNG-8238:
---------------------------------
Description:
Maven3 plugin using ModelBuilder gets this:
{noformat}
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal
eu.maveniverse.maven.plugins:toolbox:0.2.4-SNAPSHOT:gav-dm-tree (default-cli)
on project unused: Execution default-cli of goal
eu.maveniverse.maven.plugins:toolbox:0.2.4-SNAPSHOT:gav-dm-tree failed: An API
incompatibility was encountered while executing
eu.maveniverse.maven.plugins:toolbox:0.2.4-SNAPSHOT:gav-dm-tree:
java.lang.AbstractMethodError: Receiver class
eu.maveniverse.maven.mima.extensions.mmr.internal.ModelCacheImpl does not
define or inherit an implementation of the resolved method 'abstract
java.lang.Object computeIfAbsent(org.apache.maven.building.Source,
java.lang.String, java.util.function.Supplier)' of interface
org.apache.maven.model.building.ModelCache.
{noformat}
Fixing ModelCacheImpl to implement missing methods lead to another issue:
missing class {{org.apache.maven.building.Source}} (this class is used by new
methods on ModelCache interface). This class belongs to artifact
model-builder-support but this package was NEVER exported (nor in mvn3 nor in
mvn4).
Basically, we got to point, that Maven4 broke this compatibility, but there is
no way to fix it either, as required class is in not exported package.
