gradle plugin baseExtension getCompileSdkVersion为null问题

自定义了一个gradle插件,在里面用如下代码获取compileSdkVersion

代码语言:javascript复制
val plugin = project.plugins.getPlugin(AppPlugin::class.java)
        val sdkDirectory = plugin.baseExtension.sdkDirectory
        println("androidExtension compileSdkVersion:${plugin.baseExtension.compileSdkVersion}")
        val androidJarPath = "platforms/${plugin.baseExtension.compileSdkVersion}/android.jar"

发现plugin.baseExtension.compileSdkVersion的值为null,然后换一种方式获取

代码语言:javascript复制
       val androidExtension = project.extensions.getByName("android") as BaseExtension

       val androidJarPath = "platforms/${androidExtension.compileSdkVersion}/android.jar"

一样为null,查来查去不知道为什么

后来发现是apply plugin: 的地方不对,必须下面代码之后,apply,因为的逻辑是在apply里面做的

代码语言:javascript复制
android {
    compileSdkVersion 29
    buildToolsVersion "29.0.2"


    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"

        consumerProguardFiles 'consumer-rules.pro'
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

}

因为gradle文件代码执行自上而下,必须先执行了设置compileSdkVersion,在apply插件,获取的值才没问题
