从 class net.fortuna.ical4j.model.ContentBuilder 非法调用 super 到 void groovy.lang.GroovyObjectSupport.setMetaClass(groovy.lang.MetaClass)

Question

我创建了一个 Android 应用程序，我在其中解析日历事件。如果 proguard 被禁用，一切正常。当我尝试通过启用混淆器来混淆我的代码时，我收到此错误并且构建失败。

从 class net.fortuna.ical4j.model.ContentBuilder 无效 groovy.lang.GroovyObjectSupport.setMetaClass(groovy.lang.MetaClass) 的非法调用

我搜索了很多，但找不到解决这个问题的方法。

我使用 Ical4j 库的代码片段

.
.
.
Date time = cal.getTime();
Period period = new Period(new net.fortuna.ical4j.model.DateTime(time), new Dur(20, 0, 0, 0));
Filter filter = new Filter(new PeriodRule(period));
.
.
.
if (component.getProperty("ATTENDEE") != null) {
    int attendeeSize = component.getProperties("ATTENDEE").size();
    for (int a = 0; a < attendeeSize; a++) {
        attendee = (net.fortuna.ical4j.model.property.Attendee) component.getProperties("ATTENDEE").get(a);
        if (attendee.getParameter("CN") != null)
            attendeeEmail = attendeeEmail + "\n" + attendee.getParameter("CN").getValue();
    }
} 
.
.
.

这是我的proguard-rules.pro

我已经通过从 proguard-rules.pro 中删除 -dontshrink 解决了我的问题。希望这会帮助其他人面临这个问题。
