如何解决以下gradle警告？我按这行添加了库：
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 InnerClasses
编辑：尝试使用-dontoptimize
