android - 错误：找不到 io.objectbox:objectbox-gradle-plugin:1.3.4

Question

请帮忙。我正在尽一切可能将objectbox集成到一个android项目中，每次尝试都会出错。我不确定 objectbox 版本和 android studio gradle 版本之间是否存在兼容性问题。我目前正在运行 gradle 4.3.1 并集成对象 1.3.4。

project.build gradle 文件

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




 buildscript {
        //ext.objectboxVersion = '1.3.4'
        repositories {
            google()
            jcenter()
            maven {
                url "http://objectbox.net/beta-repo/"
            }

            dependencies {
                // need to include in top build file
                // https://developer.android.com/studio/build/gradle-plugin-3-0-0.html#known_issues
                classpath 'com.android.tools.build:gradle:3.0.1'
                classpath "io.objectbox:objectbox-gradle-plugin:1.4.0"
            }
        }

        allprojects {
            repositories {
                maven { url "http://objectbox.net/beta-repo/" }
                google()
                jcenter()
                mavenCentral()
            }
        }

        repositories {
            //maven { url "http://objectbox.net/beta-repo/" }
            jcenter()
            mavenCentral()
            google()
        }
    }
