android - gradle任务将在使用AS同步时运行

Question

我在app / build.gradle中创建了一个像这样的代码的依赖项assembleRelease，当我使用AS同步时收到FileNotFoundException错误

task push(type: Exec, dependsOn: ['assembleRelease']) {
    println 'push invoke'
    def apkDir = "${project.projectDir.absolutePath}/build/outputs/plugin/release/"
    def apkName = ""
    fileTree(apkDir).visit { FileVisitDetails details ->
        println "${details.name}"
        //只取第一个apk
        if (apkName.endsWith(".apk")) {
            apkName = details.name
            details.stopVisiting()
        }
    }
    if (apkName.isEmpty()) throw new FileNotFoundException("apk file not found,please invoke 'assemblePlugin' first")
    workingDir project.projectDir
    commandLine 'adb', 'push', "${project.projectDir.absolutePath}/build/outputs/plugin/release/{$apkName}", '/sdcard/Demo_plugin_1.apk'
    ignoreExitValue true
}

当我同步gradle时代码将运行？
我希望代码在执行gradlew push时运行
我该怎么办

尝试在任务的第一部分使用doFirst {}块:

doFirst {
    println 'push invoke'
    def apkDir = "${project.projectDir.absolutePath}/build/outputs/plugin/release/"
    def apkName = ""
    fileTree(apkDir).visit { FileVisitDetails details ->
        println "${details.name}"
        //只取第一个apk
        if (apkName.endsWith(".apk")) {
            apkName = details.name
            details.stopVisiting()
        }
    }
    if (apkName.isEmpty()) throw new FileNotFoundException("apk file not found,please 
     invoke 'assemblePlugin' first")
}
