使用Parse.com的Android - 在Proguard上缺少课程

我在一个项目上使用Parse . 该项目使用我自己的Android库项目，其中包含Parse jar . 当我尝试生成签名的apk时，gradle会出现以下问题：

编辑：根据@ karama的建议，我将此添加到我的proguard规则中：

-keepattributes *Annotation*
-keepattributes Signature
-dontwarn com.squareup.**
-keep class com.squareup.** { *; }

-dontwarn com.parse.ParseOkHttpClient**
-keep class com.parse.ParseOkHttpClient** { *; }

# Proguard configuration for Jackson 2.x (fasterxml package instead of codehaus package)
-keep class com.fasterxml.jackson.databind.ObjectMapper {
    public <methods>;
    protected <methods>;
}
-keep class com.fasterxml.jackson.databind.ObjectWriter {
    public ** writeValueAsString(**);
}
-dontwarn org.w3c.dom.bootstrap.DOMImplementationRegistry

然而，现在我得到以下内容：

警告：com.fasterxml.jackson.databind.ext.DOMSerializer：找不到引用的类org.w3c.dom.bootstrap.DOMImplementationRegistry警告：com.fasterxml.jackson.databind.ext.DOMSerializer：找不到引用的类org.w3c.dom.bootstrap.DOMImplementationRegistry警告：com.fasterxml.jackson.databind.ext.DOMSerializer：找不到引用的类org.w3c.dom.bootstrap.DOMImplementationRegistry警告：com.fasterxml.jackson.databind.ext .

如果我通过添加来修复它：-dontwarn org.w3c.dom.bootstrap.DOMImplementationRegistry当应用程序运行时，它会崩溃 . 我在这里看到了这个问题，但没有解决方案：https://stackoverflow.com/a/11249755/197127

使用-dontobfuscate运行应用程序正常 .
