JarTreeShakeBuildItem

public JarTreeShakeBuildItem(boolean classesShaken,
 Set<String> reachableClassNames,
 Map<io.quarkus.maven.dependency.ArtifactKey,List<String>> removedClasses)

Method Details

isClassesShaken

public boolean isClassesShaken()

getReachableClassNames

public Set<String> getReachableClassNames()

Returns:

dot-separated class names of all reachable classes

getRemovedClasses

public Map<io.quarkus.maven.dependency.ArtifactKey,List<String>> getRemovedClasses()

Returns:

sorted list of removed class resource paths (e.g. "com/example/Foo.class") per dependency

collectUnreachableEntries

public void collectUnreachableEntries(io.quarkus.maven.dependency.ResolvedDependency dep,
 Set<String> removedEntries)
                               throws IOException

Collects JAR entry paths of unreachable classes from a dependency into the given set. Handles multi-release JAR entries and preserves inner classes whose outer class is reachable.

Parameters:

dep - the dependency to scan

removedEntries - the set to add removed entry paths to

Throws:

IOException

computePedigree

public String computePedigree(io.quarkus.maven.dependency.ArtifactKey depKey)

Computes a pedigree string for the given dependency describing what was removed.

Returns:

pedigree text or null if nothing was removed
