java 7 j2html无法加载类

我试图在我的项目中使用j2html库，但我一直遇到这个编译错误

Java版本：1.7

Grails版本：2.4.3

添加了渐变依赖项：

compile'com.j2html:j2html:1.2.0'

进口：

import j2html.tags.ContainerTag
import static j2html.TagCreator.*

错误：

[groovyc] org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
  [groovyc] General error during semantic analysis: java.lang.NoClassDefFoundError: Unable to load class j2html.TagCreator due to missing dependency java/util/function/Predicate

如何解决这个问题？

谓词是在Java 1.8中添加的。那个版本的j2html支持1.7吗？根据官方网站，Java 6和7支持是从版本1.0.0开始添加的，我见过其他库也这样做，它们依赖于将目标版本设置为1.7，但这通常是针对ide的。你可能想朝那个方向看。我已经试过了，不幸的是没有运气/
