ERROR: Unable to load class 'org.gradle.api.internal.component.Usage'.

1.错误如下：

ERROR: Unable to load class 'org.gradle.api.internal.component.Usage'

2.解决方法：

将：

classpath 'com.novoda:bintray-release:0.3.4'

改为：

classpath 'com.novoda:bintray-release:0.5.0'

 然后同步一下

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }//必须添加这行
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.2'
//        classpath 'com.android.tools.build:gradle:3.5.1'
//        classpath 'com.novoda:bintray-release:0.3.4'
        classpath 'com.novoda:bintray-release:0.5.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }//必须添加这行
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
