Java libGDX生成失败，错误为无法初始化类org.codehaus.groovy.reflection.ReflectionCache

我第一次尝试使用libGDX。我在macOS 10.15.5上运行java 14.0.1和gradle 6.5.1。在子项目和扩展下指定游戏名称、类文件、sdk位置等后，我检查Android和box2D。之后，我按generate，得到以下输出：

Generating app in /Users/davidhouse/Downloads/test
Executing '/Users/davidhouse/Downloads/test/gradlew clean --no-daemon'
To honour the JVM settings for this build a new JVM will be forked. Please consider using the daemon: https://docs.gradle.org/5.4.1/userguide/gradle_daemon.html.
Daemon will be stopped at the end of the build stopping after processing
