Groovy не конвертирует замыкание в BiPredicate при использовании groovy-maven-plugin

У меня проблемы со следующим Groovy-кодом (я впервые попробовал без явных типов параметров замыкания): 

  Files.find(path, 4, { Path target, BasicFileAttributes attr ->
    def file = target.fileName
    file.toString().endsWith(".xml") && !file.toString().startsWith("_")
  },
    new FileVisitOption[0]
  ).collect(Collectors.toList())

Сбой Groovy-компилятора (2.4.15) с: 

No signature of method: static java.nio.file.Files.find() is applicable for argument types: (sun.nio.fs.UnixPath, java.lang.Integer, upgrade_bundles$_items_closure3, [Ljava.nio.file.FileVisitOption;) values: [/home/kkrason/dev/tpc2/zerocracy/farm/src/test/resources/com/zerocracy/bundles/understands_bug_label, ...]
Possible solutions: find(), find(java.nio.file.Path, int, java.util.function.BiPredicate, [Ljava.nio.file.FileVisitOption;), findAll(), any(), find(groovy.lang.Closure), wait()

Почемукомпилятор не конвертирует замыкание в BiPredicate?Существует только один метод find, поэтому я не понимаю, почему возникает конфликт.

РЕДАКТИРОВАТЬ: приведенный выше код выполняется с использованием maven:

org.codehaus.gmaven groovy-maven-plugin 2.1 upgrade-bundles process-test-resources execute compile $ {project.basedir} /upgrade_bundles.groovy

и в зависимостях проекта у меня есть: 

<dependency>
  <groupId>org.codehaus.groovy</groupId>
  <artifactId>groovy-all</artifactId>
  <version>2.4.15</version>
</dependency>

Я пытался добавить этозависимость от groovy-maven-plugin, но тогда я получаю:
