Maven 4 API - Plugin Descriptor Model

 This is the immutable model for Maven Plugin Descriptor in <<<org.apache.maven.api.plugin.descriptor>>> package.

 The following are generated from this model:

    @ParametricNullness final K key;
    int index;

    EntryForKey(int index) {
      // The cast is safe because we call forEntry only for indexes that contain entries.
      this.key = uncheckedCastNullableTToT(keys[index]);
      this.index = index;
    }

    void updateIndex() {
      if (index == ABSENT || index > size || !Objects.equals(keys[index], key)) {
        index = findEntryByKey(key);
      }
    }

        private int index = -1;
        private final int maxIndex = keyToIndex().size();

        @Override
        protected @Nullable Entry<K, V> computeNext() {
          for (index++; index < maxIndex; index++) {
            V value = getValue(index);
            if (value != null) {
              return immutableEntry(getKey(index), value);
            }
          }
