网上解决方案

Android SDK Build-tools版本不匹配，去AS的Settings下载自己需要的SDK相关配置，但对我不生效。

分享我的解决方法：

repositories {
        flatDir {
            dirs 'libs'
        }
//        maven {
//            url "http://dl.bintray.com/jlmd/maven"
//        }
    }

2、manifest merger failed with multiple errors see logs

去Terminal输入以下命令查看具体Log

 ./gradlew processReleaseManifest --stacktrace

解决：除了清单文件添加属性之外，请检查项目以及Model和三方依赖SdkVersion版本尽量保持一致

3、module java.base does not “opens java.io“ to unnamed module

添加以下代码

maven {
            url "https://jitpack.io"
        }
        mavenCentral()
