添加最后一个库，即实现文件('src/libs/selenium-server-standalone-3411.59.jar'(后，其显示如下错误，如果我删除此库，则它可以正常工作

添加库gradle后未正确同步，因此显示错误，"未找到class'.MainActivity'"：
主要问题是一些渐变文件有相同的内部文件，如：-
implementation files('src/libs/okhttp-3.11.0.jar')
implementation files('src/libs/okio-1.14.0.jar')或
implementation files('src/libs/commons-lang3-3.9.jar')
implementation files('src/libs/commons-lang3-3.9-sources.jar')
implementation files('src/libs/commons-lang3-3.9-tests.jar')
所以它没有成功同步，
或者第二种选择是使用像这样的渐变版本
implementation("com.squareup.okhttp3:okhttp:4.2.2")
implementation 'com.github.apache:commons-lang:LANG_3_8_1_RC1'
并根据您的需要放置版本。。。
主要问题是ClassNotFoundException，因此请查看此链接，并给出了许多解决方案。使用它，看看你的项目有什么用。
