Android 如何解决gradle警告：忽略匿名内部类的InnerClasses属性

如何解决以下gradle警告？我通过以下行添加了库：

implementation 'org.apache.commons:commons-collections4:4.1'


Warning:warning: Ignoring InnerClasses attribute for an anonymous inner class
(org.apache.commons.collections.ReferenceMap$1) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.

尝试在ProGuard配置中添加

-keepattributes innerClass

编辑：尝试使用

-dontoptimize
