Question

我想在Groovy中解析Json，但是它引发了异常，不知道我的代码出了什么问题，需要一些帮助

[ENV：]

jdk-9.0.4

ide：idea

lang：Groovy

异常如下：警告：发生了非法的反射访问操作警告：org.codehaus.groovy.reflection.CachedClass $ 3 $ 1的非法反射访问（文件：/ C：/Users/hhbst/.gradle/caches/modules-2/files-2.1/org.codehaus.groovy/groovy-all /2.3.11/f6b34997d04c1538ce451d3955298f46fdb4dbd4/groovy-all-2.3.11.jar）转换为方法java.lang.Object.finalize（）警告：请考虑将此报告给org.codehaus.groovy.reflection.CachedClass $ 3 $ 1的维护者警告：使用--illegal-access = warn启用有关进一步非法反射访问操作的警告警告：在将来的版本中，所有非法访问操作都将被拒绝

java.lang.ClassCastException：[B不能强制转换为[C

以退出代码-1完成的过程

@Test
void JsonParaTest(){
    def jsonSlurper = new JsonSlurper()
    def object = jsonSlurper.parseText('{ "name": "John Doe" }')

    assert object.name == 'John Doe'
}

Answer 1

这是Java 9发行时旧版本的groovy的错误

更新groovy依赖关系将对其进行修复
